AIThe SynGAP1 missense variant A1341T is listed in ClinVar (ID 837815.0) with an “Uncertain” clinical significance and is present in gnomAD (variant ID 6‑33451895‑G‑A). Functional prediction tools largely agree on a benign effect: REVEL, PROVEAN, polyPhen‑2 (HumDiv and HumVar), ESM1b, FATHMM, AlphaMissense‑Default, and AlphaMissense‑Optimized all report benign or likely benign. Only SIFT predicts a pathogenic effect. The SGM‑Consensus, derived from a majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN, also indicates a likely benign outcome. High‑accuracy assessments confirm this: AlphaMissense‑Optimized is benign, and the SGM‑Consensus is likely benign; Foldetta results are unavailable. Overall, the preponderance of evidence points to a benign impact for A1341T, which is consistent with the ClinVar “Uncertain” status rather than contradicting it.

Prediction tools cluster into two groups: benign predictions come from premPS and AlphaMissense‑Optimized, while the remaining nine tools—SGM‑Consensus, REVEL, PROVEAN, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, SIFT, ESM1b, FATHMM, and AlphaMissense‑Default—indicate pathogenicity. High‑accuracy assessments further show AlphaMissense‑Optimized as benign, SGM‑Consensus as pathogenic (a majority vote of pathogenic predictions from AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN), and Foldetta as uncertain due to conflicting FoldX‑MD and Rosetta outputs.

Glu582-Met603) and a short α helical section (res. Ser606-Phe608). In the WT simulations, the hydroxyl side chain of Ser604 periodically hydrogen bonds with the backbone carbonyl groups of other α helix residues (e.g., Pro600, Met603). Serine weakens the α helix secondary structure, and thus, Ser604 along with Pro605 breaks the α helix, facilitating the turn in the WT structure.In contrast, in the variant simulations, Leu604 forms a few hydrophobic interactions (e.g., Leu607, Phe608). More importantly, the helix end is more stable than with Ser604 in the WT. 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, Ser604 directly hydrogen bonds with Ras residues Ser65 and Ala66 in the WT SynGAP-Ras complex. The hydrophobic leucine cannot maintain these interactions with Ras at the GAP-Ras interface. Thus, the effect of the residue swap on the complex formation with the GTPase cannot be fully explored in the solvent-only simulations.

AIThe SynGAP1 E221V missense variant is reported in ClinVar as Pathogenic (ClinVar ID 2413181.0) and is not found in gnomAD. Functional prediction tools largely agree on a deleterious effect: pathogenic calls come from REVEL, PROVEAN, polyPhen‑2 HumDiv, SIFT, ESM1b, AlphaMissense‑Default, AlphaMissense‑Optimized, and the SGM‑Consensus (majority vote). Benign predictions are limited to premPS, polyPhen‑2 HumVar, and FATHMM. Uncertain results are reported by FoldX, Rosetta, and Foldetta. High‑accuracy assessments reinforce the pathogenic interpretation: AlphaMissense‑Optimized predicts Pathogenic, the SGM‑Consensus also indicates Likely Pathogenic, while Foldetta remains Uncertain. Taken together, the preponderance of evidence supports a pathogenic effect for E221V, and this conclusion aligns with the ClinVar classification, showing no contradiction.

Because the Ω loop is assumed to directly interact with the membrane, it moves arbitrarily throughout the WT solvent simulations. 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 major 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 Pro385 is potentially tolerated in the Ω loop. However, since the effects on Gly-rich Ω loop dynamics can only be well studied through the SynGAP-membrane complex, no definite conclusions can be drawn.

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 major roles in protein functions that require flexibility, and thus hydrophobic residues like leucine are rarely tolerated. Although no negative structural effects are observed in the variant simulations, Leu385 may exert drastic effects on the SynGAP-membrane complex dynamics and stability.

High‑accuracy assessments further support a pathogenic interpretation: AlphaMissense‑Optimized predicts benign, but SGM Consensus is pathogenic, and Foldetta (combining FoldX‑MD and Rosetta) predicts benign. Overall, the majority of tools favor pathogenicity, and the high‑accuracy consensus leans pathogenic, indicating the variant is most likely pathogenic, which is consistent with the ClinVar uncertain status rather than contradicting it.

The sec-butyl hydrocarbon side chain of Ile584 packs hydrophobically with residues in an inter-helix hydrophobic space (e.g., Leu588, Met477, Val473, and Ile483).In the variant simulations, the thioether hydrophobic side chain of Met584 maintains similar interactions as Ile584 in the WT, as it is roughly the same size and fits well within the hydrophobic space. Thus, the residue swap does not appear to cause any negative effects on the protein structure.

Met289-Arg299, res. Arg272-Leu286), is swapped for another hydrophobic residue, valine. In the variant simulations, the branched hydrocarbon side chain of Val289 packs against the phenol group of the Tyr291 side chain but is unable to form methionine-aromatic interactions. β hairpins are potential nucleation sites during the initial stages of protein folding, so even minor changes in them could be significant. However, based on the simulations, the residue swap does not cause adverse effects on the structure.

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, 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. 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.

In the WT simulations, Arg272 forms hydrogen bonds with the glycine-rich Ω loop residues (res. Val365-Pro398, e.g., Gly380) and creates a salt bridge with the carboxylate group of the Asp304 side chain.In the variant simulations, the carboxamide group of the Gln272 side chain does not stack with the indole ring of Trp362 as stably as the guanidinium group of Arg272 in the WT. Consequently, the Gln272 side chain is freer to interact with the loop residues than Arg272, potentially negatively affecting the dynamic SynGAP-membrane association. Additionally, Arg272 faces the RasGTPase interface, so the residue swap could impact the SynGAP-Ras complex formation and GTPase activation.

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.

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 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). Additionally, the residue swap could weaken the tertiary structure assembly and negatively affect the overall protein folding process.

Because the Ω loop is assumed to directly interact with the membrane, it moves arbitrarily throughout the WT solvent simulations. 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 major roles in protein functions that require flexibility, and thus hydrophobic residues like tryptophan are rarely tolerated. Although no major negative structural effects are observed in the variant simulations, Trp385 may exert drastic effects on the SynGAP-membrane complex dynamics and stability.

AISynGAP1 missense variant R579Q is listed in ClinVar with an uncertain significance (ClinVar ID 3964539.0) and is present in gnomAD (variant ID 6‑33440788‑G‑A). Prediction tools that classify the variant as benign include SIFT and AlphaMissense‑Optimized, whereas the majority of other in‑silico predictors (SGM‑Consensus, REVEL, premPS, PROVEAN, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, ESM1b, FATHMM, AlphaMissense‑Default) predict it to be pathogenic. High‑accuracy assessments further support this view: AlphaMissense‑Optimized reports a benign effect, SGM‑Consensus (derived from a majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN) predicts pathogenicity, and Foldetta, which integrates FoldX‑MD and Rosetta outputs, yields an inconclusive result. FoldX and Rosetta individually report uncertain effects. Overall, the preponderance of evidence from both general and high‑accuracy tools indicates that R579Q is most likely pathogenic, which is consistent with its ClinVar status of uncertain significance rather than a benign classification.

Pro364-Pro398) between two anti-parallel β sheet strands (res. Thr359-Pro364, res. Ala399-Ile411). Because the Ω loop is assumed to directly interact with the membrane, it moves arbitrarily throughout the WT solvent simulations. 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 major roles in protein functions that require flexibility, and thus, large and relatively hydrophobic residues like tyrosine are rarely tolerated. Additionally, the hydroxyl group of Tyr374 frequently forms various hydrogen bonds with other loop residues in the variant simulations. Although no negative structural effects are observed in the variant simulations, Tyr374 may exert drastic effects on the SynGAP-membrane complex dynamics and stability. However, since the effect on Gly-rich Ω loop dynamics can only be studied through the SynGAP-membrane complex, no definite conclusions can be drawn.

Taken together, the preponderance of evidence points to a pathogenic effect for P318L, which does not contradict the ClinVar uncertain status.

Asp330-Ala322, res. Thr305-Asn315), packs against the hydrophobic side chain of Ile205 at the end of the anti-parallel β sheet in the PH domain. In the variant simulations, the iso-butyl side chain of Leu318 is unable to do the same, potentially weakening the PH and C2 domain association. Importantly, the residue swap could also affect loop formation during folding, as proline can make tighter turns than leucine. Because the residue swap could affect the C2 domain stability, it could also negatively impact the SynGAP-membrane association.

Gly341-Pro349, res. Thr359-Pro364). In the WT simulations, the guanidinium group of Arg356 alternately forms salt bridges with the carboxylate groups of the GAP domain residues, Glu446 and Glu698. Arg356 also forms hydrogen bonds with the hydroxyl group of the GAP domain residue Thr691 and interacts with Met409 at the C2-GAP interface.In the variant simulations, the Cys356 mutation fails to maintain any of the Arg356 interactions and only occasionally forms weak hydrogen bonds with nearby C2 domain residues (e.g., Gln407). Although no negative structural effects are observed during the simulations, Arg356 is located at the C2 and GAP domain interface, making the residue swap potentially detrimental to the tertiary structure assembly.

AISynGAP1 missense variant S590G is listed in ClinVar (ID 1721675.0) with an uncertain significance status and is present in gnomAD (6‑33440820‑A‑G). Functional prediction tools that report a benign effect include REVEL, SIFT, FATHMM, and AlphaMissense‑Optimized. Those that predict a pathogenic effect are PROVEAN, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, AlphaMissense‑Default, and ESM1b. The high‑accuracy consensus (SGM Consensus) derived from AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN yields a pathogenic majority. Foldetta, which integrates FoldX‑MD and Rosetta outputs, is inconclusive, as are FoldX, Rosetta, and premPS. Overall, the majority of evidence points toward a pathogenic impact, which does not contradict the ClinVar uncertain status but suggests a higher likelihood of pathogenicity.

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.

Functional prediction tools that agree on a benign effect include REVEL and FATHMM, whereas a majority of tools predict a pathogenic impact: premPS, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, AlphaMissense‑Default, and the SGM‑Consensus score. Predictions that are inconclusive or unavailable are FoldX, Rosetta, Foldetta, and AlphaMissense‑Optimized. High‑accuracy assessments show AlphaMissense‑Optimized as uncertain, the SGM‑Consensus (majority vote from AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) as pathogenic, and Foldetta (combining FoldX‑MD and Rosetta outputs) as uncertain. Overall, the preponderance of evidence from multiple pathogenic‑predicting tools suggests that the variant is most likely pathogenic, which contradicts its current ClinVar benign classification.

Leu685-Val699), is not involved in any long-lasting interactions in the WT simulations. In the variant simulations, the positively charged guanidinium side chain of Arg697 occasionally forms hydrogen bonds with nearby residues, such as Ser722 and Asn719. 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.

AISynGAP1 missense variant L607V is listed in ClinVar with an uncertain significance (ClinVar ID 1450275.0) and is present in gnomAD (ID 6‑33440871‑C‑G). Prediction tools that agree on a benign effect include only AlphaMissense‑Optimized. All other evaluated algorithms—REVEL, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, FATHMM, AlphaMissense‑Default, and the SGM‑Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN)—predict a pathogenic impact. 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.

In the WT simulations, the iso-butyl side chain of Leu607 does not interact with any other residues, but it could potentially interact directly with Ras due to its location at the GAP domain.In the variant simulations, Val607, which has similar size and physicochemical properties to leucine, does not cause any negative effects on the protein structure. However, due to its location at the GAP-Ras interface, the residue swap could affect the complex formation with the GTPase, but this cannot be investigated using solvent-only simulations.

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.

Leu489-Glu519), and its carboxylate group forms salt bridges with the neighboring Lys492 and with Arg596 on an opposing α-helix (res. Glu582-Met603) in the WT simulations. 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.

AIThe SynGAP1 missense variant R573L is listed in ClinVar as Pathogenic (ClinVar ID 521291.0) and is not reported in gnomAD. Functional prediction tools that assess sequence conservation and structural impact uniformly indicate a deleterious effect: REVEL, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, FATHMM, AlphaMissense‑Default, and AlphaMissense‑Optimized all classify the substitution as pathogenic. No tool in the dataset predicts a benign outcome. Predictions that rely on protein‑folding stability (FoldX, Rosetta, Foldetta, premPS) are inconclusive and are therefore treated as unavailable. High‑accuracy assessments further support pathogenicity: AlphaMissense‑Optimized is pathogenic; the SGM Consensus, derived from the majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN, also reports pathogenic; Foldetta remains uncertain. Based on the collective evidence, the variant is most likely pathogenic, which is consistent with its ClinVar status.

Arg563-Glu578), forms a salt bridge with the carboxylate groups of Glu582 and/or Asp586 from a nearby α-helix (res. Glu582-Met603) in the WT simulations. 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, the aliphatic iso-butyl group of the Leu573 side chain fails to establish any of these interactions, which, in turn, lowers the integrity of the opposing α-helix end (res. Glu582-Met603). Overall, the residue swap has the potential to substantially affect the tertiary structure assembly during the protein folding process.10.1016/j.ajhg.2020.11.011

Only polyPhen‑2 HumDiv predicts a pathogenic outcome, while Rosetta, Foldetta, and AlphaMissense‑Default are uncertain. High‑accuracy assessments show AlphaMissense‑Optimized as **Benign**, the SGM‑Consensus as **Likely Benign**, and Foldetta as **Uncertain**. Taken together, the overwhelming majority of evidence points to a benign impact, and this conclusion aligns with the ClinVar designation. Thus, the variant is most likely benign, with no contradiction to its ClinVar status.

Due to its shorter side chain, Asp201 can also hydrogen bond with the backbone amide groups of neighboring loop residues Ser204 and Asp203. However, since the model ends abruptly at the N-terminus, no definite conclusions can be drawn from the simulations.
