AIThe SynGAP1 R10W missense variant is listed in ClinVar with an “Uncertain” status and is present in gnomAD (ID 6‑33420292‑C‑T). Prediction tools that agree on a benign effect include REVEL, PROVEAN, polyPhen‑2 HumVar, ESM1b, FATHMM, AlphaMissense‑Optimized, and the SGM‑Consensus (which itself is “Likely Benign”). Tools that predict a pathogenic effect are polyPhen‑2 HumDiv and SIFT; AlphaMissense‑Default remains uncertain. High‑accuracy assessments show AlphaMissense‑Optimized as benign, and the SGM‑Consensus (majority vote from AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) also indicates benign. Foldetta, a protein‑folding stability method combining FoldX‑MD and Rosetta outputs, has no available result for this variant. Overall, the majority of evidence points to a benign impact, and this conclusion does not contradict the ClinVar “Uncertain” classification.

AISynGAP1 variant V348M is listed in ClinVar with an uncertain significance and is not reported in gnomAD. Functional prediction tools that report a clear outcome fall into two groups: benign calls come from REVEL, Foldetta, PROVEAN, and AlphaMissense‑Optimized; pathogenic calls come from polyPhen‑2 (HumDiv and HumVar), SIFT, and FATHMM. The remaining tools (FoldX, Rosetta, premPS, AlphaMissense‑Default, ESM1b) give uncertain results, and the SGM Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) is unavailable due to no majority. 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.

Pro364-Pro398) between two anti-parallel β sheet strands (res. Thr359-Pro364 and res. Ala399-Ile411). The Ω loop is assumed to directly interact with the membrane, and it is observed to move arbitrarily throughout the WT solvent simulations. Although the residue swap does not influence the nearby secondary structure elements, proline is often found at the ends of β sheets due to its disfavored status during folding.Additionally, the Ω loop potentially plays a crucial role in the SynGAP-membrane complex association, stability, and dynamics. However, this aspect cannot be fully addressed through solvent simulations alone. Ω loops are known to play significant roles in protein functions that require flexibility, and thus hydrophobic residues like leucine are rarely tolerated. Although no negative structural effects are visualized in the variant’s simulations, Leu398 may exert drastic effects on the SynGAP-membrane complex dynamics and stability. Since the effects on the Gly-rich Ω loop dynamics can only be well studied through the SynGAP-membrane complex, no definite conclusions can be drawn.

Glu480-Leu482) within an α-α loop connecting the two α-helices (res. Ala461-Phe476 and Leu489-Glu519) at the GAP-Ras interface. In the WT simulations, His481 alternately stacks against Arg485, Arg587, and Glu480 without a definite role. In the variant simulations, Tyr481 also alternately stacks with nearby arginine residues, including Arg485, Arg587, and Arg479. The interaction between Tyr481 and Arg479 affects the α-α loop, causing it to fold into a distorted helical structure, an effect that might be more pronounced during protein folding. Finally, the potential effect of the residue swap on SynGAP-Ras complex formation or GTPase activation cannot be fully addressed using the SynGAP solvent-only simulations.

Met289-Pro298, res. Thr305-Asn315), forms hydrogen bonds that stabilize the tight turn. 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 thiol group of the Cys299 side chain is unable to form any of these well-coordinated or strong interactions, 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. 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.

Thr619-Ala634).The residue swap could weaken the integrity of the α helix, as glycine is known as an “α helix breaker.” However, no discernible difference was observed between the WT and variant simulations in this regard. Importantly, Gly590 cannot form hydrogen bonds with the opposing helix in the same way that serine can, which could weaken the tertiary structure assembly between the two helices.

In the variant simulations, the thiol group of the Cys575 side chain, which is neither positively charged nor particularly hydrophilic, packs against the hydrophobic Met470 on an opposing α-helix (res. Ala461-Arg475). Additionally, although the thiol group is not an effective hydrogen bonder, the Cys575 side chain rotates to hydrogen bond with the backbone carbonyl group of Ser571 in the same α-helix, which could theoretically lower the helix integrity. Overall, the residue swap has the potential to substantially affect the tertiary structure assembly during the protein folding process.

Pro364-Pro398) between two anti-parallel β sheet strands (res. Thr359-Pro364 and res. Ala399-Ile411). The Ω loop is assumed to directly interact with the membrane, and it is observed to move arbitrarily throughout the WT solvent simulations. This loop potentially plays a crucial role in the SynGAP-membrane complex association, stability, and dynamics. However, this aspect cannot be fully addressed through solvent simulations alone.Ω loops are known to play significant roles in protein functions that require flexibility, and so they are rich in glycine residues, prolines, and to a lesser extent, small hydrophilic residues to ensure maximum flexibility. Thus, the variant’s Glu390 may not be as well tolerated in the Ω loop. Additionally, the carboxylate group of Glu390 occasionally forms H-bonds with other loop residues in the variant simulations. The interaction between the acidic carboxylate side chain and the acidic membrane lipids may further influence the SynGAP-membrane complex. However, since the effects on the Gly-rich Ω loop dynamics can only be well studied through the SynGAP-membrane complex, no definite conclusions can be drawn.

AIThe SynGAP1 missense variant M1211K is listed in ClinVar (ID 834052.0) as benign and is not reported in gnomAD. Functional prediction tools cluster into two groups: benign predictions come from FATHMM and AlphaMissense‑Optimized, while the remaining seven tools—REVEL, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, and AlphaMissense‑Default—classify the change as pathogenic. High‑accuracy assessments further clarify the picture: AlphaMissense‑Optimized predicts a benign effect, whereas the SGM Consensus (a majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN) indicates a likely pathogenic outcome; Foldetta data are unavailable. Overall, the preponderance of evidence from standard predictors and the SGM Consensus supports a pathogenic interpretation, which contradicts the benign classification reported in ClinVar.

Arg563-Glu578 and res. Glu582-Ser604). In the WT simulations, the guanidinium group of Arg581 forms salt bridges with the carboxylate groups of Asp583 within the same helix, as well as with Glu478 and/or Glu480 on a slightly α-helical loop (res. Glu478-Thr488) preceding another α helix (res. Ala461-Phe476).In the variant simulations, the neutral carboxamide group of the Gln581 side chain cannot form any of these salt bridges. Instead, it packs hydrophobically against Met477 and Ile587 or forms hydrogen bonds sporadically with nearby residues (e.g., Asp583, Arg587). Thus, although no drastic changes are observed in the variant simulations, the residue swap could weaken the tertiary structure assembly.

AISynGAP1 missense variant Q612P is listed in ClinVar (ID 3660462.0) with an uncertain significance annotation and is not reported in gnomAD. Functional prediction tools cluster into two groups: benign predictions come from FoldX, SIFT, and AlphaMissense‑Optimized; pathogenic predictions arise from REVEL, PolyPhen‑2 (HumDiv and HumVar), ESM1b, FATHMM, AlphaMissense‑Default, PROVEAN, and the SGM Consensus score (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN). The high‑accuracy AlphaMissense‑Optimized predicts benign, whereas the SGM Consensus predicts likely pathogenic; Foldetta, a folding‑stability method combining FoldX‑MD and Rosetta outputs, returns an uncertain result and is therefore not factored into the consensus. Overall, the majority of evidence supports a pathogenic effect, which contrasts with the ClinVar uncertain classification.

Gly341-Pro349), faces outward in the C2 domain. This phenol ring contributes to a triple tyrosine stack (Tyr342, Tyr328, and Tyr281) that links together three anti-parallel β sheet strands. 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. Although these changes in surface interactions could weaken the characteristic twist that strengthens the β sheet fold, no major structural effects are observed in the variant simulations. The residue swap could also affect the SynGAP-membrane association; however, this phenomenon cannot be addressed using solvent-only simulations. Notably, the thiol group of cysteine is not a particularly strong hydrogen-bonding partner, which could mitigate the negative effects of the residue swap.

AISynGAP1 missense variant R324W is listed in ClinVar with an uncertain significance (ClinVar ID 845180.0) and is present in gnomAD (ID 6‑33437875‑C‑T). Functional prediction tools cluster into two groups: benign predictions come from REVEL, SIFT, and AlphaMissense‑Optimized; pathogenic predictions come from PROVEAN, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, ESM1b, FATHMM, and AlphaMissense‑Default. The SGM Consensus, derived from a majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN, is pathogenic. High‑accuracy assessments show AlphaMissense‑Optimized as benign, SGM Consensus as pathogenic, and Foldetta (combining FoldX‑MD and Rosetta outputs) as uncertain. No other stability or functional scores are available. Overall, the preponderance of evidence points to a pathogenic effect, which does not contradict the ClinVar uncertain status but suggests a leaning toward pathogenicity.

Prediction tools that agree on a benign effect include REVEL, FoldX, polyPhen‑2 HumVar, SIFT, FATHMM, and AlphaMissense‑Optimized. Those that predict a pathogenic effect are SGM‑Consensus, PROVEAN, polyPhen‑2 HumDiv, ESM1b, and AlphaMissense‑Default. Uncertain predictions come from Foldetta, premPS, and Rosetta. High‑accuracy assessments show AlphaMissense‑Optimized as benign, the SGM Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) as pathogenic, and Foldetta as inconclusive. Overall, the majority of tools lean toward a benign interpretation, but the high‑accuracy consensus is split, leaving the variant’s impact uncertain. Thus, the variant is most likely benign based on the bulk of predictions, and this does not contradict its ClinVar status of uncertain significance.

In the variant simulations, Lys672 can only form a hydrogen bond with the amino group of the Lys566 side chain via its backbone carbonyl group. Consequently, it cannot maintain the Lys566-Glu666 salt bridge through hydrogen bonding. However, the amino group of Lys periodically forms a salt bridge with the carboxylate group of Glu666, which prevents a drastic disruption of the hydrogen-bond network that keeps the loop close to the helices.

In the variant simulations, Asn475 forms a hydrogen bond with Arg479 on the proceeding α-α loop. The absence of Phe476/Arg475 stacking and the Arg475-Glu472 salt bridge weakens the integrity of the terminal end of the α-helix during the variant simulations.

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.

While the residue swap does not cause any apparent negative effects on the protein structure in the variant simulations, it could adversely affect the SynGAP-membrane association in reality. The positively charged Arg329 side chain forms hydrogen bonds with other loop residues (e.g., Ser371, Asp338) that are expected to dynamically interact with the membrane head group region. However, this phenomenon is beyond the scope of the solvent-only simulations to unravel.

AIThe SynGAP1 missense variant R587T is listed in ClinVar with an “Uncertain” status and is not reported in gnomAD. Prediction tools that agree on a benign effect include SIFT and AlphaMissense‑Optimized, whereas a majority of tools (REVEL, PROVEAN, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, ESM1b, FATHMM, AlphaMissense‑Default, and the SGM‑Consensus) predict a pathogenic outcome. Uncertain predictions from FoldX, Rosetta, Foldetta, and premPS are treated as unavailable. High‑accuracy assessments show AlphaMissense‑Optimized as benign, the SGM‑Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) as pathogenic, and Foldetta as uncertain. Overall, the preponderance of evidence points to a pathogenic effect for R587T, which does not contradict the ClinVar “Uncertain” classification but suggests that the variant is more likely pathogenic rather than benign.

Glu582-Met603), is constantly rotating and breaking/forming multiple hydrogen bonds and/or salt bridges at the surface intersection of α helices in the WT simulations. The positively charged Arg587 side chain can form a salt bridge with either the carboxylate group of Asp583 or Asp586 in the same helix, or with Glu480 on the opposing short helical loop structure (res. Glu480-Leu482).Importantly, the Arg587 side chain also hydrogen bonds with the backbone carbonyl groups of Ala634 and Asn635, as well as the carboxamide group of Asn635 at the end of another α helix (res. Asp616-Phe636). However, in the variant simulations, the neutral hydroxyl group of the Thr587 side chain is unable to form these salt bridges. Due to its smaller size, it also does not form the hydrogen bonds that the Arg587 side chain could. Instead, the hydroxyl group of Thr587 hydrogen bonds with the backbone carbonyl group of Asp583, which could weaken the integrity of the α helix, although this is not observed in the simulations.Overall, the residue swap could weaken the tertiary structure assembly and negatively affect the overall protein folding process.

Lys705-Leu725). In the WT simulations, the pyrrolidine side chain of Pro715, lacking the backbone amide groups altogether, forces the tight helix turn to take place while also hydrophobically packing with nearby residues (e.g., Leu700, Leu708, Leu714, and Leu718). Leu715, with a normal amide backbone, could potentially affect protein folding and turn formation, although this was not observed in the variant simulations. Additionally, the hydroxyl group of the Ser715 side chain can form hydrogen bonds with the backbone carbonyl group of Gly712 and disrupt the hydrophobic packing arrangement of the leucine residues from the neighboring α-helices, impacting the GAP domain tertiary assembly.

Thr704-Gly712), forms a salt bridge with Lys710 and a hydrogen bond with its own backbone amino group at the helix end in the WT simulations. Although Lys706 is unable to make these transient interactions in the variant simulations, there is no apparent negative effect on the protein structure due to the residue swap. However, because the model ends abruptly at the C-terminus, no definite conclusions can be drawn based on the simulations.

AIThe SynGAP1 missense variant L465V is listed in ClinVar with an uncertain significance and is not reported in gnomAD. Prediction tools cluster into two groups: benign predictions come from REVEL and SIFT, while the remaining tools—FoldX, Rosetta, premPS, PROVEAN, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, ESM1b, FATHMM, and AlphaMissense‑Default—indicate pathogenicity. High‑accuracy assessments further support a deleterious effect: AlphaMissense‑Optimized is uncertain; the SGM Consensus, derived from a majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN, reports likely pathogenic; and Foldetta, which combines FoldX‑MD and Rosetta stability outputs, predicts pathogenic. Overall, the majority of evidence points to a pathogenic impact, which is consistent with the ClinVar uncertain status and does not contradict it.

AIThe SynGAP1 Y820N variant is listed in ClinVar with an “Uncertain” significance and is not reported in gnomAD. Prediction tools that agree on a benign effect include REVEL, PROVEAN, SIFT, and FATHMM, whereas polyPhen‑2 (HumDiv and HumVar), ESM1b, and AlphaMissense‑Default all predict a pathogenic outcome. AlphaMissense‑Optimized returns an “Uncertain” result. The SGM Consensus, derived from a majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN, is inconclusive (two benign vs. two pathogenic votes). Foldetta, a protein‑folding stability method combining FoldX‑MD and Rosetta outputs, has no available result for this variant. Overall, the predictions are evenly split between benign and pathogenic, with no high‑confidence pathogenic or benign signal. Thus, the variant is most likely of uncertain significance, which is consistent with its ClinVar status.

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 guanidinium group of Arg581 forms salt bridges with the carboxylate groups of Asp583 within the same helix, as well as with Glu478 and/or Glu480 in a slightly α-helical loop (res. Glu478-Thr488) preceding another α helix (res. Ala461-Phe476).In the variant simulations, the neutral indole ring of the Trp581 side chain cannot form any of these salt bridges. Instead, it packs hydrophobically against Met477 and Ile587 without forming any direct hydrogen bonds. The tendency of the loop (res. Asp477-Thr488) to acquire an α-helical structure seems to marginally increase, potentially due to Trp581's inability to coordinate stable hydrogen bonds with the loop residues (e.g., Glu478-Arg581 salt bridge).

High‑accuracy assessments show AlphaMissense‑Optimized as uncertain, the SGM‑Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) as pathogenic, and Foldetta (combining FoldX‑MD and Rosetta stability outputs) as benign. Overall, the preponderance of evidence points to a pathogenic impact, which does not contradict the ClinVar “Uncertain” classification.

AISynGAP1 missense variant R573Q is reported in ClinVar as Pathogenic (ClinVar ID 1176819.0) and is not present in gnomAD. Functional prediction tools largely agree on a deleterious effect: pathogenic predictions come from SGM‑Consensus, REVEL, FoldX, Foldetta, premPS, PROVEAN, polyPhen‑2 (HumDiv and HumVar), ESM1b, FATHMM, and AlphaMissense‑Default, while only SIFT predicts a benign outcome. Two tools give inconclusive results: Rosetta (Uncertain) and AlphaMissense‑Optimized (Uncertain). High‑accuracy assessments further support pathogenicity: AlphaMissense‑Optimized remains uncertain, the SGM Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) is Pathogenic, and Foldetta (combining FoldX‑MD and Rosetta outputs) is Pathogenic. Overall, the preponderance of evidence indicates the variant is most likely pathogenic, consistent with its ClinVar classification.

Additionally, the Arg573 side chain stacks planarly with the aromatic phenol ring of Tyr665 and hydrogen bonds with the hydroxyl group of Ser668 from another α-helix (res. Ser641-Ser668). In the variant simulations, although the carboxamide group of the Gln573 side chain can hydrogen bond with the carboxylate group of Glu582 or the hydroxyl group of Ser668, these interactions are not as coordinated, stable, or strong as those of the positively charged Arg573. Consequently, the integrity of the opposing α-helix end (res. Glu582-Met603) is weakened. Overall, the residue swap has the potential to substantially affect the tertiary structure assembly during the protein folding process.

Gly341-Pro349), faces outward in the C2 domain. In the WT simulations, the phenol ring of Tyr342 contributes to a triple tyrosine stack (Tyr342, Tyr328, and Tyr281) that links together three anti-parallel β sheet strands. 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 Ser342 side chain cannot participate in the stack formation. Instead, the hydroxyl group of the Ser342 side chain forms a hydrogen bond with the imidazole ring of His326 in a neighboring β strand (res. Ala322-Asp330). This disrupts the formation of a hydrogen bond between His326 and the carboxylate group of the Glu283 side chain from another β strand (res. Arg279-Cys285). Although these changes in surface interactions could weaken the characteristic twist that strengthens the β sheet fold, no major structural effects are observed in the variant simulations. The residue swap could also affect the SynGAP-membrane association, as the hydroxyl group of Ser342 could form hydrogen bonds with membrane-facing loop residues. However, this phenomenon cannot be addressed using solvent-only simulations.

However, similar to Trp697 in the WT, Arg697 does not form any long-lasting interactions and thus does not induce any negative structural effects in the simulations.

AIThe SynGAP1 missense variant R279W is listed in ClinVar with an uncertain significance (ClinVar ID 1204186.0) and is not reported in gnomAD. Prediction tools that indicate a benign effect include only REVEL, whereas the remaining pathogenic‑predicating tools—FoldX, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, FATHMM, AlphaMissense‑Default, and the SGM‑Consensus—consistently predict a deleterious impact. Uncertain or inconclusive results come from Rosetta, Foldetta, premPS, 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 as uncertain. Overall, the preponderance of evidence points to a pathogenic effect for R279W, which contrasts with the ClinVar designation of uncertain significance.

Arg279-Leu286), can form hydrogen bond with the backbone carbonyl groups of nearby loop residues (e.g., Ser296, Ser331, and As332) and form salt bridges with the carboxylate groups of Asp330 and Asp332. 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.

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.
