AISynGAP1 missense variant D527Y is listed in ClinVar with an uncertain significance (ClinVar ID 1698369.0) and is not reported in gnomAD. Functional prediction tools cluster into two groups: the single benign prediction from premPS versus a consensus of pathogenic predictions from the remaining 12 tools (REVEL, SGM‑Consensus, PROVEAN, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, SIFT, ESM1b, FATHMM, AlphaMissense‑Default, AlphaMissense‑Optimized). High‑accuracy assessments further support a deleterious effect: AlphaMissense‑Optimized predicts pathogenic, the SGM Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) is likely pathogenic, and Foldetta (combining FoldX‑MD and Rosetta outputs) is inconclusive. Protein‑stability calculations from FoldX and Rosetta are also uncertain. Overall, the preponderance of evidence indicates that D527Y is most likely pathogenic, which does not contradict the current ClinVar uncertain status.

Gly502-Tyr518 and Ala533-Val560). In the WT simulations, the carboxylate group of the Asp527 side chain forms hydrogen bonds with the backbone atoms of loop residues (e.g., Ile529, Lys530) facing the membrane surface. In the variant simulations, Tyr527 is a bulkier residue that faces away from the loop and stacks with Phe646 in a nearby α-helix (res. Ser614-Ser668). Regardless, no negative structural effects are observed during the variant simulations. However, due to its location near the SynGAP-membrane interface, the effect of the residue swap cannot be fully addressed using the SynGAP solvent-only simulations.

AISynGAP1 missense variant F597L is listed in ClinVar with an uncertain significance (ClinVar ID 3658115.0) and is not reported in gnomAD. Prediction tools that classify the variant as benign include only SIFT, whereas the remaining tools—SGM‑Consensus, REVEL, Rosetta, premPS, PROVEAN, polyPhen‑2 (HumDiv and HumVar), ESM1b, FATHMM, AlphaMissense‑Default, and AlphaMissense‑Optimized—predict it to be pathogenic. The high‑accuracy AlphaMissense‑Optimized score is pathogenic, and the SGM‑Consensus (a majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN) also indicates likely pathogenic. Foldetta, which integrates FoldX‑MD and Rosetta stability outputs, is inconclusive. Overall, the preponderance of evidence points to a pathogenic effect for F597L, which is consistent with its ClinVar uncertain status rather than contradicting it.

AIThe SynGAP1 missense variant I589M is listed in ClinVar with an uncertain significance (ClinVar ID 964298.0) and is not reported in gnomAD. Functional prediction tools that provide a definitive call overwhelmingly predict a deleterious effect: REVEL, premPS, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, FATHMM, and AlphaMissense‑Default all indicate pathogenicity, and the SGM Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) also reports a likely pathogenic outcome. Tools that are inconclusive—FoldX, Rosetta, Foldetta, and AlphaMissense‑Optimized—are listed as uncertain and do not influence the overall assessment. High‑accuracy methods specifically show AlphaMissense‑Optimized as uncertain, SGM Consensus as likely pathogenic, and Foldetta as uncertain. Taken together, the majority of available predictions support a pathogenic effect, which is consistent with the ClinVar uncertain designation rather than contradicting it.

Glu582-Met603), is swapped for another hydrophobic residue, methionine. The sec-butyl hydrocarbon side chain of Ile589 packs favourably with multiple residues in the inter-helix hydrophobic space (e.g., Phe569, Ile667, and Leu664).Although the S-methyl thioether group of the Met589 side chain in the variant is longer than the branched side chain of isoleucine, it stacks favourably with the aromatic phenol ring. Additionally, the polar sulphur atom forms a weak hydrogen bond with the guanidinium group of Arg573, which in turn forms a salt bridge with the carboxylate group of Asp586.Overall, the hydrophobic packing in the inter-helix space does not appear to be disrupted in the variant simulations.

AIThe SynGAP1 missense variant G502D is listed in ClinVar with an “Uncertain” status and is not reported in gnomAD. Prediction tools that assess pathogenicity all converge on a deleterious effect: REVEL, FoldX, Rosetta, Foldetta, premPS, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, FATHMM, AlphaMissense‑Default, and AlphaMissense‑Optimized all report a pathogenic or likely pathogenic outcome. No tool in the dataset predicts a benign effect. High‑accuracy assessments reinforce this consensus: AlphaMissense‑Optimized is pathogenic; the SGM Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) is “Likely Pathogenic”; and Foldetta, which integrates FoldX‑MD and Rosetta stability calculations, is pathogenic. Based on the uniform predictions, the variant is most likely pathogenic, a conclusion that contradicts the current ClinVar “Uncertain” classification.

Leu489-Glu519). In the WT, Gly502 acts as an α-helix breaker due to its lack of a side chain, facilitating a bend in the middle of the α-helix. In the variant simulations, the carboxylate group of Asp502 forms hydrogen bonds with neighboring residues (e.g., Ser677, Lys504), disrupting the hinge. Additionally, Asp502 struggles to fit into the α-helix hinge and cannot generate a similar bend as Gly502, which would drastically affect the secondary structure during folding. Thus, the deleterious effect seen in the simulations is likely an underestimate of the impact of the residue swap on the protein structure during protein folding.

Prediction tools that assess pathogenicity all return a deleterious signal: REVEL, FoldX, Rosetta, Foldetta, premPS, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, FATHMM, AlphaMissense‑Default, and the SGM Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) all predict pathogenic. No tool reports a benign outcome. High‑accuracy assessments show AlphaMissense‑Optimized as “Uncertain,” SGM Consensus as “Likely Pathogenic,” and Foldetta (combining FoldX‑MD and Rosetta outputs) as “Pathogenic.” Overall, the variant is most likely pathogenic based on the consensus of predictive algorithms, which contradicts the current ClinVar “Uncertain” classification.

In the WT simulations, the phenol ring of Tyr497 hydrophobically packs with other residues in the inter-helix space (e.g., Leu465, Leu565, Val568). The hydroxyl group of Tyr497 also alternately forms hydrogen bonds with the carboxylate side chain of Gln456 and the backbone carbonyl of Glu564. Thus, Tyr497 plays a role in the folding and maintenance of the tertiary structure assembly between these four helices.In the variant simulations, the comparatively smaller residue, Cys497, cannot maintain any of the interactions seen with Tyr497 in the WT. Although no severe deleterious consequences are observed in the simulations, the structural effects could be more pronounced during actual protein folding. Indeed, the tertiary structure is seen to slightly break apart in the variant simulations.

In the variant simulations, the pyrrolidine side chain of Pro551 is not as optimal as leucine for hydrophobic packing with the nearby residues. Moreover, Pro551 lacks the amide group, and thus, it cannot form a hydrogen bond with the backbone carbonyl group of Cys547, which disrupts the continuity of the secondary structure element.

In the variant simulations, Pro489 is located near the beginning of the α-helix, so the residue swap with Leu489 does not affect the continuity of the secondary structure element. However, the side chain of proline is not as optimal as that of leucine for maintaining hydrophobic packing with nearby residues (e.g., Ala448, Lys444). Additionally, the consistently maintained hydrogen bond interaction between the backbone amide group of Leu489 and the carbonyl of Glu436 is lost due to the residue swap, potentially affecting the tertiary structure integrity.

In the variant simulations, the phenyl ring of the Phe489 side chain can also pack favorably in the hydrophobic region. However, due to the size difference, the aromatic side chain of Phe489 tends to reposition to escape the tight region to accommodate the larger side chain, stacking with Lys444. Although no apparent negative changes are observed during the variant simulation, the size difference between the swapped residues could affect the protein folding process.

High‑accuracy assessments further support this: AlphaMissense‑Optimized reports benign, whereas the SGM‑Consensus, derived from the majority of pathogenic predictions, indicates pathogenic. Foldetta, which integrates FoldX‑MD and Rosetta outputs, is inconclusive and therefore not considered evidence. Overall, the preponderance of computational evidence points to a pathogenic effect for L607V, a conclusion that contrasts with the current ClinVar uncertain status.

Glu666-Asp644). In the variant simulations, the pyrrolidine side chain of Pro544 cannot form any of the salt bridges that Arg544 does in the WT, potentially weakening the tertiary structure assembly. Additionally, Pro544 lacks the amide group, and thus, unlike Arg544 in the WT, is unable to form a hydrogen bond with the carbonyl of Gln540. This disruption breaks the continuity of the secondary structure element, causing the α-helix to bend slightly in the variant simulations. These negative structural effects could be more pronounced during protein folding and are likely to be undermined in the MD simulations.

Prediction tools that agree on a benign effect include only Foldetta, whereas the remaining tools (REVEL, PROVEAN, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, SIFT, ESM1b, FATHMM, AlphaMissense‑Default, AlphaMissense‑Optimized, and the SGM Consensus) uniformly predict a pathogenic impact; FoldX, Rosetta, and premPS are inconclusive. High‑accuracy assessments show AlphaMissense‑Optimized as pathogenic, the SGM Consensus as likely pathogenic, and Foldetta as benign. Overall, the majority of evidence points to a pathogenic effect, which does not contradict the ClinVar “Uncertain” classification but suggests that the variant is more likely pathogenic rather than benign.

Ala461-Phe476), stacks with the phenyl ring of Phe476 and forms a salt bridge with Glu472. Additionally, Arg475 occasionally forms another salt bridge with the carboxylate group of Glu486 on the α-α loop connecting the two α-helices (res. Ala461-Phe476 and Leu489-Glu519) at the GAP-Ras interface. Therefore, Arg475 potentially plays a key role in positioning the loop by interacting with Glu486, which is necessary for the positioning of the “arginine finger” (Arg485) and, ultimately, for RasGTPase activation.In the variant simulations, Trp475 moves and stacks with Arg479 on the proceeding α-α loop, disrupting the terminal end of the α-helix. Lastly, the potential effect of the residue swap on the SynGAP-Ras complex formation or GTPase activation cannot be fully addressed using the SynGAP solvent-only simulations.

AIThe SynGAP1 E496G missense variant is listed in ClinVar with an “Uncertain” status and is not reported in gnomAD. Prediction tools that assess the variant’s effect fall into two groups: no tool predicts a benign outcome, while eight tools (REVEL, PROVEAN, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, SIFT, ESM1b, FATHMM, AlphaMissense‑Default) all predict a pathogenic effect. The SGM‑Consensus, which is a majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN, also indicates a likely pathogenic outcome. High‑accuracy assessments are mixed: AlphaMissense‑Optimized is uncertain, the SGM‑Consensus remains likely pathogenic, and Foldetta (combining FoldX‑MD and Rosetta outputs) is uncertain. Overall, the preponderance of evidence points to a pathogenic effect, contradicting the current ClinVar “Uncertain” classification.

Glu496 also forms a hydrogen bond with Ser449 on an opposing helix (res. Val441-Ser457). In the variant simulations, Gly496 cannot form these salt bridges, which could weaken the secondary structure. Additionally, the loss of the hydrogen bond with Ser449 on the opposite helix can weaken the tertiary structure assembly. Moreover, glycine is an α-helix breaker, and it is seen to weaken the integrity of the helix as the hydrogen bonding between the backbone atoms of Gly496 and Ala493 breaks down. Also, due to its location at the GAP-Ras interface, the interaction of Glu496 with Arg499 and Lys492 might play a role in complex association and stability, which cannot be fully addressed using the SynGAP solvent-only simulations.

In the WT simulations, the sec-butyl side chain of Ile510 hydrophobically packs with other residues in the inter-helix space (e.g., Leu506, Leu610, Ile514, Ile602, Leu598). In the variant simulations, the hydroxyl group of Ser510 forms a hydrogen bond with the backbone atoms of Leu506 and Gly511 in the same α-helix, which could further weaken the α-helix integrity. This α-helix already shows weakness in the WT simulations due to Gly511. Although the simulations do not show large-scale effects, the residue swap could have a substantial impact due to the fundamental role of hydrophobic packing during protein folding.

Regardless, the potential negative effect is likely to be minor, with no deleterious effects observed on the protein structure during the simulations.

AIThe SynGAP1 missense variant S520F is listed in ClinVar with an uncertain significance and is not reported in gnomAD. Functional prediction tools that classify the variant as benign include Rosetta, Foldetta, and premPS. Those that predict pathogenicity are REVEL, PROVEAN, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, SIFT, ESM1b, FATHMM, AlphaMissense‑Default, and AlphaMissense‑Optimized. FoldX gives an uncertain result. High‑accuracy assessments further support a deleterious effect: AlphaMissense‑Optimized predicts pathogenicity, the SGM Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN) indicates likely pathogenic, whereas Foldetta, a protein‑folding stability method combining FoldX‑MD and Rosetta outputs, predicts a benign impact. Overall, the majority of evidence points to a pathogenic effect, which does not contradict the ClinVar uncertain status.

Ala533-Val560) next to an α-α loop between two α-helices (res. Gly502-Tyr518 and Ala533-Val560). In the WT simulations, the carboxamide group of the Asn542 side chain forms a hydrogen bond with the backbone carbonyl group of Asn523 and packs favourably against Glu522 from the loop. In contrast, in the variant simulations, the hydroxyl group of the Ser542 side chain is unable to maintain either the hydrogen bond with Asn523 or the packing against the Glu522 side chain. Instead, the hydroxyl group of Ser542 occasionally forms a hydrogen bond with the backbone carbonyl group of Glu538.Altogether, the residue swap results in a looser helix-loop association, which is especially evident in the third replica simulation, where Asn523 moves away from its initial placement next to the α-helix. In short, based on the simulations, the residue swap weakens the GAP domain tertiary structure assembly, which in turn could negatively affect protein folding.

AIThe SynGAP1 missense variant N556I is catalogued in ClinVar as benign (ClinVar ID 2692844.0) and is observed in gnomAD (ID 6‑33438910‑A‑T). Functional prediction tools cluster into two groups: benign predictions come from Rosetta, Foldetta, and premPS, while pathogenic predictions arise from REVEL, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, FATHMM, AlphaMissense‑Default, and the SGM‑Consensus score. Two tools report uncertainty: FoldX and AlphaMissense‑Optimized. High‑accuracy assessments show AlphaMissense‑Optimized as uncertain, the SGM‑Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) as pathogenic, and Foldetta (integrating FoldX‑MD and Rosetta outputs) as benign. Taken together, the majority of predictions favor a pathogenic effect, whereas the ClinVar annotation indicates benign. Thus, the computational evidence contradicts the ClinVar status, suggesting the variant is more likely pathogenic rather than benign.

AISynGAP1 missense variant R515H is listed in ClinVar with an uncertain significance (ClinVar ID 638438.0) and is present in gnomAD (variant ID 6‑33438787‑G‑A). Prediction tools that agree on a benign effect include AlphaMissense‑Default and AlphaMissense‑Optimized. Those that predict a pathogenic impact comprise REVEL, premPS, PROVEAN, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, SIFT, ESM1b, and FATHMM. The SGM Consensus, derived from a majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN, reports a likely pathogenic classification. High‑accuracy assessments show AlphaMissense‑Optimized as benign, while the SGM Consensus remains pathogenic; Foldetta, which integrates FoldX‑MD and Rosetta outputs, is inconclusive. Overall, the balance of evidence favors a pathogenic effect, which does not contradict the ClinVar uncertain status.

Gly502-Tyr518), forms salt bridges with the carboxylate groups of Glu512 on the same helix and Glu217 on a loop in the PH domain. Additionally, the positively charged Arg515 side chain forms hydrogen bonds with Leu610 and Gln612 in an opposing loop (res. Gly609-Asp616). In contrast, in the variant simulations, the imidazole ring of His515 cannot form salt bridges with either of the acidic residues, and its side chain is too short to form hydrogen bonds with the loop residues. Accordingly, the residue swap could weaken the tertiary structure assembly of the protein. Due to the missing N-terminal part of the SynGAP model, the effect could be largely underestimated or missing. Notably, the doubly protonated and positively charged form of histidine was not simulated here.

AIThe SynGAP1 missense variant S520P is listed in ClinVar with an “Uncertain” status and is not reported in gnomAD. Prediction tools that assess pathogenicity all converge on a deleterious effect: REVEL, FoldX, Rosetta, Foldetta, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, FATHMM, AlphaMissense‑Default, and AlphaMissense‑Optimized all report a pathogenic outcome, while premPS remains inconclusive. No tool predicts a benign effect. High‑accuracy assessments reinforce this view: AlphaMissense‑Optimized is pathogenic; the SGM Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) is “Likely Pathogenic”; and Foldetta, which integrates FoldX‑MD and Rosetta stability calculations, is pathogenic. Overall, the evidence strongly supports a pathogenic impact for S520P, and this conclusion does not contradict the ClinVar “Uncertain” classification.

AIThe SynGAP1 missense variant F569S is listed in ClinVar (ID 1878965.0) as Pathogenic and is not reported in gnomAD. Across the available in‑silico predictors, every tool examined (REVEL, FoldX, Rosetta, Foldetta, premPS, PROVEAN, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, SIFT, ESM1b, FATHMM, AlphaMissense‑Default, AlphaMissense‑Optimized) classifies the variant as pathogenic; no tool predicts a benign effect. High‑accuracy assessments reinforce this view: AlphaMissense‑Optimized predicts pathogenic, the SGM Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) indicates Likely Pathogenic, and Foldetta (combining FoldX‑MD and Rosetta outputs) also predicts pathogenic. Thus, the variant is most likely pathogenic, and this prediction aligns with its ClinVar status.

Ala533-Val560, res. Arg563-Glu578, and res. Ser641-Glu666). In the variant simulations, the acceptor/donor hydroxyl group of Ser569 forms hydrogen bonds with the carbonyl groups of Glu567 and Lys566 on the same α-helix, which could affect the α-helix integrity, although this is not observed in the simulations. While the simulations do not show large-scale effects, the residue swap could have a substantial impact on the protein structure due to the fundamental role of hydrophobic packing during protein folding.

In the variant simulations, the hydrophilic side chain of Thr468 does not pack favorably in the hydrophobic niche, and the methionine-aromatic stacking is lost. Although the hydroxyl group of Thr468 forms an H-bond with the backbone carbonyl group of Phe464, the integrity of the α helix is not affected in the simulations.

AISynGAP1 missense variant A537V is listed in ClinVar as Benign (ClinVar ID 766762.0) and is present in gnomAD (ID 6‑33438853‑C‑T). Functional prediction tools that agree on a benign effect include REVEL, Rosetta, Foldetta, premPS, PROVEAN, SIFT, ESM1b, AlphaMissense‑Default, and AlphaMissense‑Optimized. Tools that predict a pathogenic effect are polyPhen‑2 HumDiv, polyPhen‑2 HumVar, and FATHMM. High‑accuracy assessments further support a benign outcome: AlphaMissense‑Optimized is benign; the SGM Consensus, derived from the majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN, is benign; and Foldetta, which integrates FoldX‑MD and Rosetta stability calculations, is benign. FoldX alone is uncertain and therefore not considered evidence. Overall, the consensus of available predictions indicates that the variant is most likely benign, in agreement with its ClinVar classification.

In the WT simulations, the hydroxyl side chain of Ser535 forms hydrogen bonds with nearby residues (e.g., His539, Glu538) without any specific interactions. These hydrogen bonds disrupt the structure of the terminal end of the α-helix (Ala533-Ser535), causing it to weaken or unfold during the WT simulations. In the variant simulations, Thr535, a hydrophilic residue with a hydroxyl group of almost the same size as Ser, interacts more frequently with the preceding loop residues (e.g., Thr532, Cys531) due to its longer side chain. Regardless, the residue swap is tolerated in the simulations with no negative effects. However, due to its location near the SynGAP-membrane interface, the effect of the residue swap cannot be fully addressed using the SynGAP solvent-only simulations.10.1016/j.ajhg.2020.11.011

The high‑accuracy AlphaMissense‑Optimized score is benign, the SGM Consensus (majority vote from AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) is inconclusive due to a 2‑vs‑2 split, and Foldetta predicts a benign effect. No other high‑accuracy or folding‑stability methods provide additional evidence. Overall, the majority of predictions support a benign impact, which does not contradict the ClinVar Uncertain status.

Ala533-Val560). The carboxamide group of Asn556 forms hydrogen bonds with nearby residues such as Lys553 and Cys552. It also forms a hydrogen bond with the backbone carbonyl group of Cys552, which weakens the α-helix integrity. In the variant simulations, the hydroxyl group of Ser556 forms a more stable hydrogen bond with the backbone carbonyl oxygen of the same helix residue, Cys552, compared to Asn556 in the WT. Serine has a slightly lower propensity to reside in an α-helix than asparagine, which may exacerbate the negative effect on the α-helix integrity. However, the residue swap does not cause negative structural effects during the simulations.

AIThe SynGAP1 missense variant M468V is listed in ClinVar with an uncertain significance and is not reported in gnomAD. Functional prediction tools cluster into two groups: benign predictions come from PROVEAN, SIFT, and AlphaMissense‑Optimized, while pathogenic predictions are made by REVEL, FoldX, Rosetta, Foldetta, polyPhen‑2 (HumDiv and HumVar), ESM1b, and FATHMM. The remaining tools, premPS and AlphaMissense‑Default, return uncertain results. High‑accuracy assessments further clarify the variant’s impact: AlphaMissense‑Optimized predicts a benign effect; the SGM Consensus, derived from a majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN, indicates pathogenicity; and Foldetta, which integrates FoldX‑MD and Rosetta outputs, also classifies the variant as pathogenic. Overall, the preponderance of evidence points to a pathogenic effect, which does not contradict the ClinVar designation of uncertain significance.

AISynGAP1 missense variant R581Q is reported in ClinVar as benign (ClinVar ID 1388591.0) and is present in gnomAD (ID 6‑33440794‑G‑A). Prediction tools that agree on a benign effect include REVEL, Rosetta, Foldetta, SIFT, and AlphaMissense‑Optimized. Tools that predict a pathogenic effect are PROVEAN, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, FATHMM, AlphaMissense‑Default, and the SGM‑Consensus (majority vote from AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN). High‑accuracy assessments show AlphaMissense‑Optimized as benign, SGM‑Consensus as pathogenic, and Foldetta as benign. No other high‑confidence stability predictions are available. Overall, the predictions are mixed, with a slight bias toward benign outcomes from the majority of tools and the high‑accuracy AlphaMissense‑Optimized and Foldetta results. Therefore, the variant is most likely benign based on the current computational evidence, which is consistent with its ClinVar benign classification.

Gly341-Pro349) to have a slight twist. Within a β strand, side chains normally alternate between outward and inward positions, but glycine is an exception as it allows the alternating pattern to skip a residue. Introducing serine or any other residue with a side chain at position 344 prevents this unique skip in the alternating pattern, causing structural strain or likely preventing correct folding altogether. Additionally, Tyr342 shields Gly344 from the solvent, contributing to twist formation in the β sheet and stabilizing the β-strand.In the variant simulations, the side chain of Ser344 assumes the inward position. However, the hydrophobic niche formed by multiple C2 domain residues (e.g., Val365, Val343, Leu327) is not accommodating for its hydroxyl group. The outward position, not seen in the simulations, would be equally disadvantageous due to the presence of hydrophobic residues on that side as well (e.g., Leu345, Tyr342). Serine is also not well-suited for twist formation, as it tends to suppress twisting and bending in β sheets. At this position, the hydroxyl group of Ser344 could also form hydrogen bonds with the backbone atoms of the Gly-rich Ω loop in the C2 domain (e.g., Thr366, Leu367, Gly378; res. Pro364-Pro398), potentially adversely affecting membrane-loop dynamics and ultimately compromising the stability of the SynGAP-membrane association.

Glu273-Lys278) connecting two anti-parallel β sheet strands, packs against multiple hydrophobic residues facing the β sheet (e.g., Ala271, Leu327, Tyr280, Val306). The hydrophilic carboxamide group of the Gln274 side chain is not suitable for this hydrophobic niche, causing nearby residues to adjust to make room for the hydrophilic glutamine. Additionally, a new hydrogen bond forms with the backbone carboxyl group of Arg272 in another β strand (res. Glu273-Arg259).As a result, the backbone amide group of Ala399 and the carbonyl group of Arg272, which connect two β strands at the β sheet end, form fewer hydrogen bonds in the variant than in the WT simulations. Although no major secondary structure disruption is observed in the variant simulations, the residue swap could profoundly affect the C2 domain folding, as the hydrophobic packing of Leu274 is crucial for maintaining the loop's contact with the rest of the C2 domain. Lastly, because the Leu274-containing loop faces the membrane surface, the residue swap could also negatively impact the SynGAP-membrane association.

Thr305-Asn315), packs against multiple hydrophobic residues (e.g., Ile268, Val306, Cys282). The indole group of Trp308 also hydrogen bonds with the backbone atoms of the C2 domain residues forming the anti-parallel β sheet (e.g., Tyr280, Thr294). The introduced Cys308 is smaller than the tryptophan it replaced. The thiol group of the Cys308 side chain is well-suited for the inner hydrophobic part of the C2 domain. Although the negative effects are essentially missing from the simulations, the side chain size difference between the residues is likely to disrupt the hydrophobic packing during folding. At a minimum, the residue swap could affect the C2 domain stability and membrane association.

AIThe SynGAP1 missense variant L264Q is listed in ClinVar with an “Uncertain” status and is not reported in gnomAD. Prediction tools that assess pathogenicity all converge on a deleterious effect: REVEL, FoldX, Rosetta, Foldetta, premPS, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, FATHMM, AlphaMissense‑Default, and AlphaMissense‑Optimized all predict pathogenicity. No tool in the dataset predicts a benign outcome. High‑accuracy methods reinforce this view: AlphaMissense‑Optimized is pathogenic; the SGM Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) is “Likely Pathogenic”; and Foldetta, which integrates FoldX‑MD and Rosetta stability calculations, is pathogenic.

In the variant simulations, the hydrophilic carboxamide group of the Gln264 side chain is not suitable for the hydrophobic niche, causing the hydrophobic residues to make room for the swapped residue. Additionally, the carboxamide group of Gln264 forms hydrogen bonds with the backbone amide groups of Arg405 and Lys256 in the β sheet and the carbonyl group of Val350 in an α helical section of a nearby loop (res. Pro359-Phe358). The residue swap disrupts the packing of the C2 domain, which could adversely affect the C2 domain structure during folding. This disruption could potentially weaken the stability of the SynGAP-membrane association.

In the variant simulations, Leu562 packs more favorably with the nearby hydrophobic residues, and the backbone amide group of Leu562 (absent in proline) does not form any intra-protein hydrogen bonds. However, prolines are well-suited for unstructured regions like loops, and thus, Pro562 in the WT is necessary at the end of the helix to induce a tight turn during folding. Although no negative structural effects are observed during the simulations, the residue swap could potentially cause extensive damage to the protein structure during folding.10.1016/j.ajhg.2020.11.011

Thus, the variant is most likely pathogenic based on the prevailing predictions, and this assessment does not contradict the ClinVar uncertain status.

AIThe SynGAP1 D287Y missense variant is reported in ClinVar as Pathogenic (ClinVar ID 2263930.0) and is not found in gnomAD. Functional prediction tools show a split: benign calls come from FoldX, Rosetta, Foldetta, and premPS, whereas pathogenic calls are made by REVEL, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, FATHMM, AlphaMissense‑Default, AlphaMissense‑Optimized, and the SGM‑Consensus. High‑accuracy assessments give a pathogenic verdict from AlphaMissense‑Optimized, a Likely Pathogenic consensus from SGM, and a benign outcome from Foldetta. Overall, the majority of evidence points to a deleterious effect. Therefore, the variant is most likely pathogenic, in agreement with its ClinVar classification.

Arg279-Leu286, res. Met289-Pro298), maintains a salt bridge with the guanidinium group of Arg324 in the β sheet during the WT simulations. In the variant simulations, the phenol group of the Tyr287 side chain is unable to form a salt bridge with the guanidinium group of Arg324, which could weaken the tertiary structure assembly of the C2 domain. However, the phenol group of Tyr287 frequently stacks with the Arg324 guanidinium side chain, which could help maintain the tertiary structure, especially compared to the D287H variant. The destabilization of the C2 domain could adversely affect the stability of the SynGAP-membrane association.

AISynGAP1 missense variant S300F is listed in ClinVar with an uncertain significance and is not reported in gnomAD. Functional prediction tools that classify the variant as benign include REVEL, FoldX, Rosetta, Foldetta, premPS, and AlphaMissense‑Optimized. Those that predict pathogenicity are PROVEAN, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, SIFT, ESM1b, and FATHMM. The remaining tool, AlphaMissense‑Default, gives an uncertain result. High‑accuracy assessments show AlphaMissense‑Optimized as benign, the SGM Consensus (majority vote from AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN) as pathogenic, and Foldetta (combining FoldX‑MD and Rosetta outputs) as benign. Overall, the majority of predictions lean toward pathogenicity, while two high‑accuracy methods support a benign effect. Thus, the variant is most likely pathogenic based on the current computational evidence, which does not contradict its ClinVar status of uncertain significance.

Met289-Pro298, res. Thr305-Asn315), hydrogen bonds with the guanidinium group of Arg299 and the backbone amide group and side chain of Ser302. Thus, in the WT simulations, it contributes to the β hairpin stability. In the variant simulations, the phenol ring of Phe300 cannot form any side chain-related hydrogen bonds, and Arg299 is moved away from its central hairpin loop position.β hairpins are potential nucleation sites during the initial stages of protein folding, so even minor changes in them could be significant. Due to its location near the membrane surface, the residue swap could also affect the C2 loop dynamics and SynGAP-membrane association. However, this is beyond the scope of the solvent-only simulations to unravel.

AIThe SynGAP1 missense variant L327P (ClinVar ID 660421.0) is reported as Pathogenic and is not present in gnomAD.

No tool predicts a benign outcome. High‑accuracy assessments corroborate this: AlphaMissense‑Optimized predicts pathogenic; the SGM Consensus (majority vote from AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) yields a Likely Pathogenic verdict; and Foldetta, which integrates FoldX‑MD and Rosetta stability calculations, also reports pathogenic. Consequently, the variant is most likely pathogenic, and this prediction aligns with its ClinVar status.

In contrast, in the variant simulations, the introduction of Pro327 destabilizes the hydrogen bonding between the two anti-parallel β strands because proline lacks the backbone amide group altogether. Additionally, in the WT simulations, the iso-butyl side chain of Leu327 packs against multiple hydrophobic residues (e.g., Leu274, V400, Val343), whereas the less bulky cyclic five-membered pyrrolidine ring of Pro327 cannot fill the same space as effectively. Thus, although no large-scale unfolding is observed during the variant simulations, the residue swap is likely to cause severe problems for the correct C2 domain folding, which could also affect the SynGAP-membrane association.10.1016/j.ajhg.2020.11.011

High‑accuracy methods specifically show AlphaMissense‑Optimized as benign, Foldetta as benign, and the SGM Consensus is not available. With four benign and four pathogenic predictions, the evidence is evenly split, providing no definitive direction. Therefore, the variant is not clearly benign or pathogenic based on current predictions, and this lack of consensus does not contradict its ClinVar uncertain status.

In the variant simulations, the bulky side chain of Arg282 with its positively charged guanidinium group is not suitable for this hydrophobic niche. Consequently, the hydrophobic residues must either make room to accommodate Arg282 or it must escape the hydrophobic C2 domain core.As a result, new hydrogen bonds are formed with the backbone carbonyl groups of the surrounding β sheet residues Ala399, Leu325, and His326, which decreases the unity of the secondary structure elements. Notably, it is likely that the residue swap causes major problems during the C2 domain folding that are not visible in the variant simulations.

In the variant simulations, the hydroxyl-containing side chain of Ser282 is more hydrophilic and, hence, not as favorable as Cys282 for this hydrophobic niche. Due to this polarity difference, the residue swap could potentially weaken the hydrophobic packing of the C2 domain during the folding process.Moreover, because the C2 domain interacts with the membrane, there could also be a negative effect on the stability of the SynGAP-membrane association. However, no large-scale structural changes were observed during the variant simulations. The hydroxyl group of Ser282 forms a hydrogen bond with the backbone carbonyl group of His326 in another β strand (res.

Gly341-Pro349), allows the strand to end and make a tight turn before a short α helical section within a loop connecting to another β strand (res. Thr359-Pro364). In the variant simulations, the hydroxyl group of Ser349 forms a hydrogen bond with the backbone amide group of Ala351 in the short helical section. Conversely, the backbone amide group of Ser349 (absent in proline) does not form any intra-protein hydrogen bonds. However, the β strand end connects to the α helical section in a more stable and consistent manner compared to the WT. Although the residue swap does not cause major adverse effects on the protein structure in the simulations, it is possible that the tight turn at the β strand end could not be created during folding without the presence of proline.

AISynGAP1 missense variant R335C is listed in ClinVar with an uncertain significance (ClinVar ID 2835865.0) and is present in gnomAD (ID 6‑33437908‑C‑T). Functional prediction tools cluster into two groups: benign predictions come from REVEL and premPS, whereas pathogenic predictions are made by PROVEAN, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, SIFT, ESM1b, FATHMM, and AlphaMissense‑Default. Predictions that are inconclusive are AlphaMissense‑Optimized, FoldX, Rosetta, and Foldetta. High‑accuracy assessments show AlphaMissense‑Optimized as uncertain, the SGM Consensus (derived from the unanimous pathogenic vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN) as pathogenic, and Foldetta as uncertain. Overall, the majority of evidence points to a pathogenic effect. This conclusion aligns with the ClinVar designation of uncertain significance, which does not contradict the prediction that the variant is most likely pathogenic.

In the WT simulations, the Arg299 side chain hydrogen bonds with the loop backbone carbonyl groups (e.g., Ser302, Thr305, Leu274, Gly303), the hydroxyl group of Ser300, and even forms a salt bridge with the carboxylate group of Asp304.In the variant simulations, the imidazole ring of His299 (epsilon protonated state) hydrogen bonds with the carbonyl group of Asp304 and the hydroxyl group of Ser300. However, it does not form as many or as strong interactions as arginine, which could affect the initial formation of the secondary hairpin loop during folding. β hairpins are potential nucleation sites during the initial stages of protein folding, so even minor changes in them could be significant.Additionally, His299 prefers to hydrophobically interact with other hydrophobic residues inside the C2 domain core (e.g., Val306, Leu274), which destabilizes the C2 domain. Indeed, the β strand partially unfolds during the second simulation. Moreover, the positively charged Arg299 side chain faces the polar head group region of the inner leaflet membrane and could directly anchor the C2 domain to the membrane. In short, the residue swap could negatively affect both protein folding and the stability of the SynGAP-membrane association.

Additionally, it shields Gly344 from the solvent, reducing its exposure and providing stability for the β-sandwich. This motif also contributes to a twist formation in the β sheet.In the variant simulations, the Cys342 side chain cannot participate in the stack formation. Instead, its thiol group forms a hydrogen bond with the backbone carbonyl group of Leu327.

However, in the variant simulations, the negatively charged carboxylate group of the Asp306 side chain is not suitable for this hydrophobic niche. Consequently, the side chain moves out to interact with Ser300 in the β strand (res.

This drastic effect could potentially reflect the challenge presented by the residue swap during the C2 domain folding.

Due to its location near the membrane surface, the residue swap could also affect the C2 loop dynamics and SynGAP-membrane association. However, this is beyond the scope of the solvent-only simulations to unravel.

AIThe SynGAP1 missense variant V320I is listed in ClinVar with an “Uncertain” status and is not reported in gnomAD. Prediction tools that uniformly indicate a benign effect include REVEL, FoldX, premPS, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, AlphaMissense‑Default, and AlphaMissense‑Optimized. Only FATHMM predicts a pathogenic outcome, while Rosetta remains inconclusive. High‑accuracy assessments corroborate the benign trend: AlphaMissense‑Optimized is benign; the SGM Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) is “Likely Benign”; and Foldetta, which integrates FoldX‑MD and Rosetta outputs, also predicts benign. Overall, the preponderance of evidence points to a benign effect for V320I, and this conclusion does not conflict with the current ClinVar designation of uncertainty.

AISynGAP1 D288N is listed in ClinVar with an uncertain significance (ClinVar ID 2572204.0) and is present in gnomAD (6‑33437767‑G‑A). Computational predictors are divided: benign calls come from REVEL, FoldX, Rosetta, Foldetta, premPS, and AlphaMissense‑Optimized, while pathogenic calls come from PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, and FATHMM; AlphaMissense‑Default is uncertain. High‑accuracy assessments show AlphaMissense‑Optimized as benign, Foldetta as benign, and the SGM Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) as likely pathogenic. Because the majority of high‑accuracy tools predict benign and the overall split of predictions is even, the variant is most likely benign, which does not contradict the ClinVar status of uncertain.

Consequently, the Gln272 side chain is freer to interact with the loop residues than Arg272, potentially negatively affecting the dynamic SynGAP-membrane association.

In the WT simulations, Arg279 sporadically forms a salt bridge even with the carboxylate group of Glu613, loosely connecting the C2 domain and GAP domain. Meanwhile, the indole ring of the Trp279 side chain is unable to hydrogen bond with the loop residues in the variant simulations. The lack of hydrogen bond or salt bridge formation with the loop residues could be significant, as Arg279 and the loops face the polar head group region of the membrane. Thus, although Trp279 could interact with the membrane surface as a “lipid anchor,” any changes to the wider loop dynamics could still adversely affect the formation of a stable SynGAP-membrane association. However, no definite conclusions on the effect of the residue swap on the SynGAP-membrane association can be drawn from solvent-only simulations.

AIThe SynGAP1 missense variant R485S is listed in ClinVar with an “Uncertain” status and is not reported in gnomAD. Prediction tools that agree on a benign effect include only FoldX, which scores the variant as benign. In contrast, the majority of tools predict a pathogenic impact: REVEL, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, FATHMM, AlphaMissense‑Default, AlphaMissense‑Optimized, and the SGM‑Consensus (which is a majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN). Tools that return uncertain results are Rosetta, Foldetta, and premPS. High‑accuracy assessments show AlphaMissense‑Optimized as pathogenic, the SGM‑Consensus as likely pathogenic, and Foldetta as inconclusive. Overall, the preponderance of evidence points to a pathogenic effect for R485S, which is consistent with the ClinVar “Uncertain” classification rather than contradicting it.

AIThe SynGAP1 missense variant S296A (ClinVar ID 469166.0) is listed as ClinVar status Uncertain and is not present in gnomAD. Functional prediction tools largely agree on a benign effect: REVEL, Rosetta, Foldetta, premPS, PROVEAN, SIFT, ESM1b, AlphaMissense‑Default, and AlphaMissense‑Optimized all predict benign or neutral. In contrast, polyPhen‑2 (HumDiv and HumVar) and FATHMM predict pathogenic. Grouping by consensus, the benign‑predicting tools outnumber the pathogenic ones. High‑accuracy assessments reinforce this view: AlphaMissense‑Optimized is benign; the SGM Consensus, derived from a majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN, is also benign; and Foldetta, which integrates FoldX‑MD and Rosetta stability calculations, reports a benign effect. No evidence from the available tools suggests a deleterious impact. Therefore, the variant is most likely benign, and this conclusion is consistent with its ClinVar status of Uncertain rather than pathogenic.

The backbone carbonyl group of Ser296 also hydrogen bonds with the guanidinium group of Arg279 in another nearby β strand (res. Arg279-Cys285). In the variant simulations, the methyl group of the Ala296 side chain cannot hydrogen bond with Asp330, causing the carboxylate group positioning to fluctuate more than in the WT simulations.Although the residue swap does not seem to affect the anti-parallel β sheet assembly during the simulations, it is possible that the Ser296-Asp330 hydrogen bond plays a crucial role in maintaining the C2 domain fold. Notably, because Ser296 is located near the membrane interface, the potential effect of the residue swap on the SynGAP-membrane association cannot be addressed by solvent-only simulations.

Glu273-Lys278) that connects two anti-parallel β sheet strands, is replaced with another negatively charged residue, aspartate. Because the C2 domain loop faces the membrane surface, the potentially crucial role of the carboxylate group of Glu273 or Asp273 on SynGAP-membrane association cannot be fully explored via solvent-only simulations.As a minor note, the neighboring residue Arg272, which stacks with the indole ring of the Trp362 side chain and directly faces RasGTPase, forms a salt bridge more often with Asp273 than with the non-mutated Glu273 in the simulations. Regardless, due to the similar physicochemical properties of the WT and variant residues at the membrane interface, the residue swap is likely to be well tolerated.

AIThe SynGAP1 missense variant I721S is listed in ClinVar with an “Uncertain” status and is not reported in gnomAD. Prediction tools that assess the variant’s effect fall into two groups: the single benign prediction comes from REVEL, while all other evaluated algorithms (FoldX, Rosetta, Foldetta, premPS, PROVEAN, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, SIFT, ESM1b, FATHMM, AlphaMissense‑Default, AlphaMissense‑Optimized) predict a pathogenic outcome. High‑accuracy methods reinforce this view: AlphaMissense‑Optimized reports pathogenic, the SGM Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) is “Likely Pathogenic,” and Foldetta (combining FoldX‑MD and Rosetta outputs) also predicts pathogenic. No predictions are missing or inconclusive. Based on the overwhelming consensus of pathogenic predictions, the variant is most likely pathogenic, which does not contradict its current ClinVar “Uncertain” classification.

Leu714-Arg726), engages in hydrophobic packing with other residues in the hydrophobic inter-helix space, such as Phe420, Tyr417, His693, and Leu717. In the variant simulations, the hydroxyl side chain of Ser721 forms hydrogen bonds with nearby residues, such as Leu717 and His693. Although no major structural changes are observed during the variant simulations, the hydrophilic residue Ser721 could disrupt the hydrophobic packing during folding. However, because the model ends abruptly at the C-terminus, no definite conclusions can be drawn based on the simulations.

AISynGAP1 missense variant E1218V is listed in ClinVar with an uncertain significance (ClinVar ID 1015602.0) and is not reported in gnomAD. Functional prediction tools show a split opinion: benign predictions come from REVEL and ESM1b, whereas pathogenic predictions are made by PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, FATHMM, and AlphaMissense‑Default. When the high‑accuracy consensus is considered, AlphaMissense‑Optimized is uncertain, but the SGM‑Consensus—derived from a majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN—labels the variant as likely pathogenic. Foldetta, a protein‑folding stability method that integrates FoldX‑MD and Rosetta outputs, has no available result for this change. Overall, the majority of evidence points toward a pathogenic effect, which is consistent with the ClinVar designation of uncertain significance rather than a benign classification.

Ala461–Phe476), packs with hydrophobic residues (e.g., Phe464, Met468, Tyr497, Ile494) in an inter-helix space formed with two other α helices (res. Ala461–Phe476 and res. Thr488-Gly502). In the variant simulations, the cyclic five-membered pyrrolidine ring of Pro465 is not as optimal as the side chain of Leu465 for filling the three α helix hydrophobic niche. Although the residue swap does not cause a large-scale conformational shift during the simulations, the H-bond between the backbone amide group of Leu465 and the backbone carbonyl group of Ala461 is lost. This, in turn, breaks the continuity of the α helix secondary structure element.
