AIThe SynGAP1 missense variant I510S is listed in ClinVar as Pathogenic (ClinVar ID 449946.0) and is not reported in gnomAD. Prediction tools that assess the variant’s effect all converge on a deleterious outcome: 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 indicate pathogenicity. No tool predicts a benign effect. High‑accuracy assessments further support this: AlphaMissense‑Optimized is uncertain, SGM‑Consensus is pathogenic, and Foldetta (combining FoldX‑MD and Rosetta outputs) is pathogenic. Based on the collective evidence, the variant is most likely pathogenic, and this prediction aligns with its ClinVar status.

Gly502-Tyr518) within the inter-helix space of three helices (res. Gly502-Tyr518, Ala533-Val560, and res. Glu582-Met603). 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.

AIThe SynGAP1 missense variant L664S is listed in ClinVar as Benign (ClinVar ID 2429773.0) and is present in gnomAD (ID 6‑33441250‑T‑C). Prediction tools that report a benign effect include only FATHMM; all other evaluated algorithms (REVEL, FoldX, Rosetta, Foldetta, premPS, PROVEAN, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, SIFT, ESM1b, AlphaMissense‑Default, AlphaMissense‑Optimized) predict a pathogenic impact, and the SGM‑Consensus score is “Likely Pathogenic.” High‑accuracy methods give the following results: AlphaMissense‑Optimized predicts Pathogenic; the SGM Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) also yields Pathogenic; and Foldetta (combining FoldX‑MD and Rosetta outputs) predicts Pathogenic. Based on the overwhelming majority of pathogenic predictions—including the high‑accuracy tools—the variant is most likely pathogenic, which contradicts its ClinVar benign classification.

Ser641-Glu666), hydrophobically interacts with residues in the inter-helix space between three helices (res. Glu617-Asn635, res. Glu582-Met603, and res. Ser641-Glu666), such as Ile589, Phe663, and Met660. In the variant simulations, the hydroxyl group of Ser664 forms hydrogen bonds with the backbone carbonyl oxygen of another helix residue, such as Met660 or Gln661. This interaction is known to destabilize hydrogen bonding in the α-helix, but this effect was not observed in the simulations. Additionally, Ser664 occasionally forms hydrogen bonds with the carboxylate group of Asp586 on another α-helix (res. Glu582-Met603), which could minimally influence the tertiary structure assembly. Despite these interactions, no major negative effects on the protein structure were observed during the simulations.

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 H1163D is listed in ClinVar with an uncertain significance and is not reported in gnomAD. Functional prediction tools show a split: benign calls come from REVEL, SIFT, ESM1b, and FATHMM, while pathogenic calls come from PROVEAN, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, and AlphaMissense‑Default. High‑accuracy assessments are inconclusive: AlphaMissense‑Optimized rates the variant as uncertain, the SGM Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) yields a tie and is therefore unavailable, and Foldetta folding‑stability analysis is not provided. With an equal number of benign and pathogenic predictions and no decisive high‑accuracy evidence, the variant remains ambiguous. Thus, it is most likely neither clearly benign nor pathogenic, and this uncertainty aligns with its ClinVar status of uncertain significance.

In contrast, the imidazole ring of His335, which is not double protonated and thus not positively charged in the variant simulations, continues to move dynamically without forming any lasting or strong interactions. Importantly, the positively charged arginine residues of the C2 domain are ideal membrane anchors for ensuring SynGAP-membrane association.

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.

In the variant simulations, the imidazole ring of His575 (in its neutral epsilon protonated form) cannot form the same salt bridges as the guanidinium group of the non-mutated Arg575. Instead, His575 only forms weak hydrogen bonds with the hydroxyl groups of Ser466 and Ser571.

In the WT simulations, the side chain of Arg596 hydrogen bonds with the backbone carbonyl groups of Asn487, Glu486, Arg485, and Phe484. Additionally, Arg596 can hydrogen bond with the carboxamide group of the Asn487 side chain on an opposing loop that links two α helices (res. Ala461-Arg475, res. Leu489-Glu519).In the variant simulations, the imidazole ring of His596 can form hydrogen bonds with the same residues as arginine; however, these interactions are not as coordinated or strong in comparison. Thus, the residue swap could affect the tertiary structure assembly more profoundly than observed in the simulations. Notably, Arg596 plays a key role in positioning the aforementioned loop, which is crucial for the placement of the “arginine finger” or the Arg485 side chain during RasGTPase activation.

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 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.

AISynGAP1 missense variant R321H is listed in ClinVar with an uncertain significance and is present in gnomAD (variant ID 6‑33437867‑G‑A). Functional prediction tools that agree on a benign effect include REVEL, FoldX, Rosetta, Foldetta, PROVEAN, SIFT, AlphaMissense‑Default, and AlphaMissense‑Optimized. Tools that predict a pathogenic outcome are polyPhen‑2 HumDiv, polyPhen‑2 HumVar, ESM1b, and FATHMM, while premPS remains uncertain. High‑accuracy assessments show AlphaMissense‑Optimized as benign, Foldetta as benign, and the SGM Consensus (majority vote from AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) is inconclusive due to a 2‑to‑2 split. Overall, the majority of predictions support a benign impact, and this consensus does not contradict the ClinVar uncertain status.

Similarly, in the variant simulations, the imidazole ring of His321 also points outward without making any stable intra-protein interactions. Thus, the residue swap does not seem to cause adverse effects on the protein structure based on the simulations. However, β hairpins are potential nucleation sites during the initial stages of protein folding, so even minor changes in them could be significant.

AISynGAP1 missense variant R329H is listed in ClinVar with an uncertain significance (ClinVar ID 2074400.0) and is present in gnomAD (ID 6‑33437891‑G‑A). Functional prediction tools that agree on a benign effect include REVEL, FATHMM, and AlphaMissense‑Optimized. Tools that agree on a pathogenic effect include FoldX, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, and AlphaMissense‑Default. High‑accuracy assessments show AlphaMissense‑Optimized predicts benign, while the SGM Consensus—derived from a majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN—predicts pathogenic. Foldetta, which integrates FoldX‑MD and Rosetta outputs, yields an uncertain result and is treated as unavailable evidence. Overall, the balance of predictions favors a pathogenic impact, which does not contradict the ClinVar uncertain status but suggests the variant is more likely deleterious.

Ala322-Asp330), faces the negatively charged lipid bilayer surface. 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. Notably, histidine can also be double protonated and positively charged, but this alternative protonation state was not considered in the variant simulations.

Arg279-Leu286), packs against multiple hydrophobic residues (e.g., Ile268, Leu284, Trp308, Leu327). 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. Ala322-Arg329), which competes directly with the backbone amide group of Glu283 within the secondary structure element.

AIThe SynGAP1 missense variant L353P is listed in ClinVar with an uncertain significance and is not reported in gnomAD. Functional prediction tools show a strong bias toward pathogenicity: REVEL predicts benign, whereas FoldX, Rosetta, premPS, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, FATHMM, and AlphaMissense‑Default all predict pathogenic. Two tools report uncertainty: ESM1b and AlphaMissense‑Optimized. High‑accuracy assessments further support a deleterious effect: AlphaMissense‑Optimized is inconclusive, SGM‑Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) predicts pathogenic, and Foldetta (combining FoldX‑MD and Rosetta outputs) also predicts pathogenic. Overall, the majority of evidence points to a pathogenic impact, which is consistent with the ClinVar designation of uncertain significance but leans toward pathogenicity rather than benign. Thus, the variant is most likely pathogenic, and this prediction does not contradict the ClinVar status.

While the backbone amide group of Leu431 forms an H-bond with the carbonyl group of His427, the cyclic five-membered pyrrolidine ring of Pro431, lacking the necessary amide group, cannot do the same. Thus, although the cyclic five-membered pyrrolidine ring of Pro431 packs almost as favorably as the side chain of Leu431 in the hydrophobic niche, the residue swap causes the α helix to partially unfold in the variant simulations.

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.

Functional prediction tools that agree on a benign effect include REVEL, PROVEAN, ESM1b, FATHMM, AlphaMissense‑Default, and AlphaMissense‑Optimized. In contrast, polyPhen‑2 (HumDiv and HumVar) and SIFT all predict a pathogenic impact. The SGM‑Consensus, which aggregates the majority vote from AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN, reports the variant as “Likely Benign.” High‑accuracy assessments further support a benign classification: AlphaMissense‑Optimized predicts benign, and the SGM‑Consensus (majority vote) also indicates benign. The Foldetta protein‑folding stability analysis is unavailable for this variant. Overall, the majority of evidence—including high‑accuracy tools—points to a benign effect, and this conclusion does not contradict the ClinVar “Uncertain” designation.

AISynGAP1 missense variant E495D is listed in ClinVar with an uncertain significance (ClinVar ID 2000233.0) and is not reported in gnomAD. Functional prediction tools cluster into two groups: benign predictions from SIFT and ESM1b, and pathogenic predictions from REVEL, PROVEAN, polyPhen‑2 (HumDiv and HumVar), FATHMM, AlphaMissense‑Default, and AlphaMissense‑Optimized. The high‑accuracy consensus (SGM Consensus) derived from AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN classifies the variant as likely pathogenic. AlphaMissense‑Optimized also predicts pathogenicity, whereas Foldetta, which integrates FoldX‑MD and Rosetta outputs, remains uncertain. Overall, the majority of evidence points to a pathogenic effect, which does not contradict the ClinVar uncertain status but suggests a higher likelihood of deleterious impact.

In the variant simulations, the acidic carboxylate side chain of Asp495 can also form salt bridges with both Lys492 and Arg596. However, the shorter side chain of aspartate tends to favor forming a salt bridge with the nearby Arg499 on the same α-helix instead. Asp495 might not maintain the salt bridge with Arg596 on the opposing α-helix as efficiently as Glu495 in the WT, potentially weakening the tertiary structure. Regardless, the potential negative effect is likely to be minor, with no deleterious effects observed on the protein structure during the simulations. However, due to its location at the GAP-Ras interface, the effect of the residue swap on SynGAP-Ras complex formation or GTPase activation cannot be fully addressed using the SynGAP solvent-only simulations.

Prediction tools that indicate a benign effect include REVEL, FATHMM, and AlphaMissense‑Optimized, whereas the majority of other in silico predictors (FoldX, Foldetta, premPS, PROVEAN, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, SIFT, ESM1b, AlphaMissense‑Default) report a pathogenic outcome; Rosetta remains inconclusive. High‑accuracy assessments further support a deleterious impact: AlphaMissense‑Optimized predicts benign, but the SGM Consensus—derived from a majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN—leans pathogenic, and Foldetta (combining FoldX‑MD and Rosetta outputs) also predicts pathogenic. Overall, the preponderance of evidence points to a pathogenic effect for the variant, which does not contradict the current ClinVar “Uncertain” classification.

Functional prediction tools that reach consensus classify the variant as benign: FoldX, Foldetta, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, FATHMM, and AlphaMissense‑Optimized. Tools that predict pathogenicity include REVEL, PROVEAN, and SIFT. Predictions that are inconclusive or uncertain are Rosetta, premPS, AlphaMissense‑Default, and ESM1b. High‑accuracy assessments further support a benign outcome: AlphaMissense‑Optimized is benign, Foldetta is benign, while the SGM Consensus (derived from AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN) is inconclusive due to a 1‑to‑1 split between benign and pathogenic calls. Overall, the majority of evidence points to a benign effect, which does not contradict the ClinVar designation of uncertain significance.

Cys219-Thr224). Its hydroxyl group forms hydrogen bonds with nearby residues Thr228 and Lys207 in the variant simulations, similar to the hydroxyl group of Thr223 in the WT simulations. These hydrogen-bonding interactions at the β sheet surface contribute to the stability of the secondary structure element and may prevent it from unfolding. However, since the model ends abruptly at the N-terminus, no definite conclusions can be drawn from the 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.

AISynGAP1 E310D is reported in ClinVar (ID 975473.0) as Pathogenic and is not found in gnomAD. Prediction tools that assess the variant’s effect all converge on a deleterious outcome: REVEL, FoldX (uncertain), Rosetta, Foldetta, premPS, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, FATHMM, AlphaMissense‑Default, and AlphaMissense‑Optimized all indicate pathogenicity, leaving no tool in the benign category. High‑accuracy methods reinforce this view: AlphaMissense‑Optimized predicts Pathogenic; the SGM Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) is Likely Pathogenic; and Foldetta, which integrates FoldX‑MD and Rosetta outputs, also reports Pathogenic. The single uncertain result from FoldX is treated as unavailable. Overall, the variant is most likely pathogenic, and this assessment is consistent with its ClinVar classification.

Because the carboxylate group can also interact with the GAP domain residues (e.g., Gln612, Tyr614), Glu310 potentially plays a key role in maintaining the tertiary assembly between the C2 and GAP domains. In the variant simulations, the carboxylate group of Asp310 can form the same interactions as glutamate; however, due to its one hydrocarbon shorter length, the connections are less stable or less optimal.

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.

The pyrrolidine side chain of Pro605 packs hydrophobically with nearby hydrophobic residues (e.g., Ile514, Leu623, Leu610) in the inter-helix space. Additionally, proline lacks a free backbone amide group, which breaks the α helix and facilitates the turn in the WT structure.In the variant simulations, the hydroxyl side chain of Ser605 forms hydrogen bonds with the backbone carbonyl groups of Ala601 and Ile602. Importantly, the helix end is more stable than with Pro605 in the WT. Indeed, proline is a more effective secondary structure breaker compared to serine.Thus, the residue swap could have a more profound effect on the actual folding process, for example, by preventing the bending at the α helix end, than what the simulations suggest. Moreover, due to its location at the GAP-Ras interface, the residue swap could affect the GAP-Ras association.

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.

P734S
2D
AIThe SynGAP1 missense variant P734S is listed in ClinVar with an uncertain significance (ClinVar ID 2283225.0) and is present in the gnomAD database (gnomAD ID 6‑33441665‑C‑T). Functional prediction tools uniformly classify the variant as benign: REVEL, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, FATHMM, AlphaMissense‑Default, and AlphaMissense‑Optimized all report benign effects. No tool predicts pathogenicity. The high‑accuracy consensus methods corroborate this benign assessment: AlphaMissense‑Optimized is benign, and the SGM Consensus (majority vote from AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN) indicates a likely benign outcome. Foldetta, a protein‑folding stability predictor combining FoldX‑MD and Rosetta outputs, did not provide a result for this variant, so its status is unavailable. Overall, the computational evidence strongly supports a benign classification, which is consistent with the ClinVar uncertain status rather than contradicting it.

AIThe SynGAP1 missense variant T532P is listed in ClinVar as Benign (ClinVar ID 1598909.0) and is not reported in gnomAD. Prediction tools that agree on a benign effect include REVEL, FoldX, Rosetta, Foldetta, premPS, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, AlphaMissense‑Default, AlphaMissense‑Optimized, and the SGM Consensus (majority vote). Only FATHMM predicts a pathogenic outcome. High‑accuracy assessments—AlphaMissense‑Optimized, the SGM Consensus, and Foldetta (combining FoldX‑MD and Rosetta outputs)—all indicate a benign impact. No prediction or folding‑stability result is missing or inconclusive. Based on the collective evidence, the variant is most likely benign, and this conclusion is consistent with its ClinVar status.

Gly502-Tyr518 and Ala533-Val560) facing the membrane. In the WT simulations, the hydroxyl group of Thr532 occasionally forms hydrogen bonds with the backbone atoms of other loop residues without any specific interaction. In the variant simulations, the Pro532 residue swap does not cause structural changes. Although hydrophilic residues seem more favorable in the loop, the pyrrolidine side chain of proline is well suited for unstructured protein regions such as loops. However, due to its location at the SynGAP-membrane interface, the effect of the residue swap cannot be fully addressed using the SynGAP solvent-only simulations.

AIThe SynGAP1 missense variant T691P is listed in ClinVar (ID 648126.0) as Pathogenic and is not reported in gnomAD. Across the broad panel of in‑silico predictors, three tools (REVEL, SIFT, FATHMM) classify the change as benign, whereas the remaining 11 predictors (FoldX, Rosetta, Foldetta, premPS, PROVEAN, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, ESM1b, AlphaMissense‑Default, and the SGM‑Consensus score) report it as pathogenic. High‑accuracy assessments further support a deleterious effect: the AlphaMissense‑Optimized model is inconclusive, the SGM‑Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) is pathogenic, and the Foldetta stability analysis (combining FoldX‑MD and Rosetta outputs) is pathogenic. Taken together, the preponderance of evidence indicates that T691P is most likely pathogenic, which is consistent with its ClinVar classification and does not contradict the database status.

This interaction facilitates the simultaneous formation of salt bridges between Arg687 and Glu688 on the same α-helix. Additionally, Thr691 occasionally interacts with the thioether side chain of Met409 in an anti-parallel β-sheet of the C2 domain (res. Ile411-Ala399), although this interaction is not consistently maintained throughout the WT simulations. In the variant simulations, the pyrrolidine side chain of Pro691 lacks hydrogen bond donors, making a similar setup impossible. Moreover, proline lacks a free amide group necessary for hydrogen bonding with the carbonyl group of Arg687, introducing a slight bend in the α-helix and compromising its integrity.

In the variant simulations, the positively charged side chain of Lys468 rotates outward to escape the hydrophobic niche, forming an H-bond with the hydroxyl group of the Ser471 side chain and a salt bridge with the carboxylate group of the Glu472 side chain. This residue swap also disrupts the methionine-aromatic stacking with the phenyl ring of the Phe464 side chain. Although no large-scale structural changes are observed during the variant simulations, the importance of hydrophobic packing suggests that the effects could be more pronounced during 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 E706K is listed in ClinVar with an uncertain significance and is not reported in gnomAD. Functional prediction tools largely agree on a benign effect: REVEL, premPS, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, and FATHMM all classify the change as benign. In contrast, ESM1b and AlphaMissense‑Default predict a pathogenic impact. Tools that return uncertain results—FoldX, Rosetta, Foldetta, and AlphaMissense‑Optimized—do not provide decisive evidence. The SGM Consensus, derived from a majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN, is inconclusive (two pathogenic versus two benign calls). High‑accuracy assessments are likewise ambiguous: AlphaMissense‑Optimized is uncertain, Foldetta is uncertain, and the SGM Consensus remains inconclusive. Overall, the preponderance of evidence points to a benign effect, which does not contradict the ClinVar uncertain status.

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 E310K is listed in ClinVar with an “Uncertain” status and is not reported in gnomAD.

No tool in the dataset 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 outputs, is pathogenic. Consequently, the variant is most likely pathogenic based on the available predictions, and this conclusion does not contradict the ClinVar “Uncertain” classification.

Thr305-Asn315), is ideally positioned to interact with the side chain hydroxyl and backbone amide groups of Thr295 on a twisted anti-parallel β strand (res. Met289-Arg299). Because the carboxylate group can also interact with the GAP domain residues (e.g., Gln612, Tyr614), Glu310 plays a key role in maintaining the tertiary assembly between the C2 and GAP domains. In the variant simulations, the amino group of the Lys310 side chain hydrogen bonds with the GAP domain residues and forms a salt bridge with Glu613. Although no apparent negative effects are seen due to the residue swap, it is possible that the loss of hydrogen bonding with the hydroxyl group of the Thr295 side chain causes problems during folding, potentially compromising the twisting of the β sheet.
