AIThe SynGAP1 missense variant D987G (ClinVar ID 1061058.0) is listed as ClinVar status Uncertain and is not reported in gnomAD. Functional prediction tools show a split: benign predictions come from REVEL, SIFT, and ESM1b, whereas pathogenic predictions are reported by PROVEAN, polyPhen‑2 (HumDiv and HumVar), FATHMM, and AlphaMissense‑Default. The SGM‑Consensus, which aggregates majority votes from AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN, classifies the variant as Likely Pathogenic. High‑accuracy assessments further indicate that AlphaMissense‑Optimized is uncertain, while Foldetta data are unavailable. Overall, the majority of evidence points toward a pathogenic effect, aligning with the SGM‑Consensus but contradicting the ClinVar Uncertain designation. Therefore, the variant is most likely pathogenic based on current predictions, and this assessment is in conflict with the ClinVar status.

AIThe SynGAP1 missense variant R884W is listed in ClinVar with an “Uncertain” status and is present in the gnomAD database (gnomAD ID 6‑33443202‑C‑T). 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, derived from a majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN, reports a “Likely Benign” classification. High‑accuracy assessments further support a benign outcome: AlphaMissense‑Optimized is benign, and the SGM‑Consensus is also benign. No Foldetta (protein‑folding stability) result is available for this variant. Overall, the majority of computational predictions, including the high‑accuracy tools, indicate that R884W is most likely benign, which is consistent with the ClinVar “Uncertain” status rather than contradicting it.

Ser641-Glu666), is not involved in any interactions in the WT simulations. In the variant simulations, the shorter side chain of Thr642 forms hydrogen bonds with Glu643 and Thr640 on the same α helix.Regardless, Lys642 is positioned directly at the GAP-Ras interface, and in the SynGAP-Ras WT simulations, its amino side chain forms salt bridges with the carboxylate groups of Ras residues Asp33 and Asp38. The shorter Thr642 is more likely to prefer hydrogen bonding with Glu643 and Thr640 on the same α helix, even in the Ras complex. Thus, the effect of the residue swap on the complex formation with the GTPase cannot be explored using solvent-only simulations.

Those that predict a pathogenic impact comprise REVEL, FoldX, Rosetta, Foldetta, polyPhen‑2 (HumDiv and HumVar), SIFT, and ESM1b. The SGM Consensus, derived from a majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN, yields a benign outcome. High‑accuracy assessments show AlphaMissense‑Optimized as benign, Foldetta as pathogenic, and the SGM Consensus as benign. Because the majority of conventional tools favor pathogenicity while the high‑accuracy subset is split, the overall evidence leans toward a pathogenic effect. This conclusion does not contradict the ClinVar uncertain status, which remains unresolved.

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 hydrophobic residues like tryptophan are rarely tolerated. Although no major negative structural effects are observed in the variant simulations, Trp379 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

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.

AISynGAP1 missense variant A591P is listed in ClinVar with an uncertain significance and is not reported in gnomAD. Functional prediction tools largely converge on a pathogenic effect: pathogenic predictions come from FoldX, Rosetta, Foldetta, premPS, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, AlphaMissense‑Default, and the SGM‑Consensus (Likely Pathogenic). Benign predictions are limited to REVEL and FATHMM. High‑accuracy assessments reinforce the pathogenic view: 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) also indicates pathogenic. Consequently, the variant is most likely pathogenic, a conclusion that contrasts with its ClinVar uncertain status.

Prediction tools that classify the variant as benign include premPS, PROVEAN, SIFT, ESM1b, AlphaMissense‑Default, AlphaMissense‑Optimized, and the SGM‑Consensus. Tools that predict pathogenicity are REVEL, FoldX, Rosetta, Foldetta, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, and FATHMM. High‑accuracy assessments show AlphaMissense‑Optimized as benign, the SGM‑Consensus (majority vote from AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) as benign, and Foldetta (combining FoldX‑MD and Rosetta outputs) as pathogenic. With two high‑accuracy tools supporting benign and one supporting pathogenic, the overall prediction leans toward a benign effect. This conclusion aligns with the ClinVar benign classification, so there is no contradiction with the existing clinical annotation.

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 thus hydrophobic residues like valine are rarely tolerated. Although no negative structural effects are visualized in the variant’s simulations, Val391 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.

In the variant simulations, the positively charged guanidinium group of Arg702 forms a salt bridge with the negatively charged carboxylate group of Glu698 on the same helix and/or hydrogen bonds with the backbone carbonyl group of Ala438 on an opposite α-helix (res. Tyr428-Glu436). Consequently, the residue swap could strengthen the tertiary structure assembly, which could have either positive or negative effects on its function.

AISynGAP1 missense variant R732T is listed in ClinVar with an uncertain significance and is not reported in gnomAD. Functional prediction tools cluster into two groups: benign (REVEL, PROVEAN, SIFT, FATHMM, AlphaMissense‑Optimized) and pathogenic (polyPhen‑2 HumDiv, polyPhen‑2 HumVar, ESM1b). AlphaMissense‑Default remains uncertain. The high‑accuracy AlphaMissense‑Optimized predicts a benign effect, and the SGM Consensus—derived from a majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN—also favors a benign outcome. Foldetta, a protein‑folding stability method that integrates FoldX‑MD and Rosetta outputs, has no available result for this variant. Overall, the preponderance of evidence from both general and high‑accuracy predictors points to a benign impact, which does not contradict the current ClinVar designation of uncertain significance.

Glu582-Met603), forms hydrogen bonds with the backbone carbonyl of Ala634 and/or the carboxamide group of the Asn635 side chain at the end of the opposing α helix (res. 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.

AISynGAP1 missense variant I584M is listed in ClinVar with an uncertain significance (ClinVar ID 1301269.0) and is present in gnomAD (6‑33440804‑C‑G). Consensus from multiple in‑silico predictors shows a split: benign calls come from REVEL, FoldX, Rosetta, Foldetta, SIFT, and AlphaMissense‑Optimized, whereas pathogenic calls arise from premPS, PROVEAN, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, ESM1b, and FATHMM. The SGM Consensus, derived from a majority vote of AlphaMissense‑Default (uncertain), ESM1b, FATHMM, and PROVEAN, is pathogenic. 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.

AIThe SynGAP1 missense variant S668F is reported in ClinVar as Pathogenic (ClinVar ID 1309930.0) and is not found in gnomAD. Functional prediction tools largely agree on a deleterious effect: benign predictions come from premPS and FATHMM, while the remaining 12 tools (REVEL, FoldX, Rosetta, Foldetta, PROVEAN, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, SIFT, ESM1b, AlphaMissense‑Default, AlphaMissense‑Optimized, and the SGM Consensus) predict pathogenicity. High‑accuracy assessments reinforce this view: AlphaMissense‑Optimized is Pathogenic; the SGM Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) is Pathogenic; and Foldetta, which integrates FoldX‑MD and Rosetta outputs, is also Pathogenic. No predictions are inconclusive. Overall, the computational evidence strongly supports a pathogenic effect, consistent with the ClinVar classification. Therefore, the variant is most likely pathogenic based on the consensus of prediction tools, and this assessment aligns with its ClinVar status.

Ser641-Glu666 and res. Leu685-Val699), forms hydrogen bonds with the backbone carbonyl groups of Leu664, Tyr665, and Glu666, as well as the guanidinium group of Arg573 on a nearby α-helix (res. Arg563-Glu578). In the variant simulations, the side chain of Phe668 cannot maintain the same hydrogen-bond network. Due to its larger size, it moves away to avoid steric hindrance. In the WT simulations, a network of hydrogen bonds between several residues (e.g., Asn669, Lys566, and Glu666) keeps both α-helices and the proceeding loop (res. Asn669-Asp684) tightly connected, but this setup is not present in the variant simulations. Additionally, in the variant simulations, the side chain of Arg573 shifts to form a more stable salt bridge with the carboxylate group of Glu582 instead of hydrogen bonding with Ser668 as in the WT simulations.

AIThe SynGAP1 missense variant F420S (ClinVar ID 981441.0) is reported as Pathogenic in ClinVar and is not present in gnomAD. Prediction tools largely agree on a deleterious effect: all listed predictors except FATHMM return a pathogenic or likely pathogenic call. The single benign prediction comes from FATHMM. High‑accuracy assessments reinforce this view: AlphaMissense‑Optimized predicts Pathogenic; the SGM Consensus (majority vote from AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN) yields Likely Pathogenic; and Foldetta, which integrates FoldX‑MD and Rosetta stability outputs, also predicts Pathogenic. No predictions or folding‑stability results are missing or inconclusive. Based on the consensus of these tools, the variant is most likely pathogenic, consistent with its ClinVar status.

Met414-Glu436), packs against hydrophobic residues in the interhelix area of the GAP domain (e.g., Leu689, Leu714, Leu717, Leu718). Although no large-scale adverse effects are seen in the variant simulations, the polar hydroxyl group of Ser420 is not suitable for the hydrophobic inter-helix space. Thus, the residue swap could affect protein folding. In theory, the introduced hydroxyl group could also lower the α helix integrity by H-bonding with the backbone atoms of neighboring residues in the same α helix. However, no such effect is seen in the variant simulations.

Met414-Glu436), forms a salt bridge with the amino group of the Lys444 side chain on an opposing α helix (res. Val441-Ser457). The backbone carbonyl of Glu436 also H-bonds with the Lys444 side chain, which helps keep the ends of the two α helices tightly connected. In contrast, in the variant simulations, the salt bridge formation with Lys444 is not possible. Instead, the repelled Lys436 side chain rotates outward, causing a change in the α helix backbone H-bonding: the amide group of Lys444 H-bonds with the carbonyl of Ala433 instead of the carbonyl of Cys432.

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.

Leu696-Leu685), can form hydrogen bonds with the backbone carbonyl and the side chain guanidinium group of Arg687. 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.

AIThe SynGAP1 missense variant I494R is listed in ClinVar as Pathogenic (ClinVar ID 1685460.0) and is not reported in gnomAD. Prediction tools that assess functional impact all converge on a pathogenic outcome: REVEL, FoldX, Rosetta, Foldetta, premPS, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, FATHMM, AlphaMissense‑Default, and AlphaMissense‑Optimized all indicate pathogenicity. 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 (combining FoldX‑MD and Rosetta outputs) is pathogenic. Thus, the variant is most likely pathogenic, and this prediction aligns with its ClinVar status.

In the variant simulations, the bulkier and positively charged residue, Arg494, weakens the integrity of the opposing helix. Additionally, the bulkier Arg494 stacks with Phe484, causing the α-helices to move farther apart to accommodate it. This mutation could have substantial negative effects due to the fundamental role of hydrophobic packing, which is disrupted by Arg494 during protein folding.

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 glycines, prolines, and, to a lesser extent, small hydrophilic residues to ensure maximum flexibility. Thus, the variant’s Ser384 is potentially tolerated in the Ω loop, although the hydroxyl group of Ser384 forms various hydrogen bonds with several other loop residues in the variant simulations.

AISynGAP1 missense variant L711V is listed in ClinVar with an uncertain significance and is present in gnomAD (ID 6‑33441596‑C‑G). Prediction tools that indicate a benign effect include REVEL, FATHMM, and AlphaMissense‑Optimized. The majority of other in silico predictors—FoldX, Rosetta, Foldetta, premPS, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, and AlphaMissense‑Default—classify the change as pathogenic, and the SGM‑Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) reports it as likely pathogenic. High‑accuracy assessments further show AlphaMissense‑Optimized as benign, SGM‑Consensus as likely pathogenic, and Foldetta (combining FoldX‑MD and Rosetta outputs) as pathogenic. Overall, the preponderance of evidence points to a pathogenic effect, which does not conflict with the ClinVar designation of uncertain significance.

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.

Taken together, the preponderance of evidence points to a benign impact for R429Q, which does not contradict the current ClinVar “Uncertain” classification.

Met414-Glu436), either forms a salt bridge with the carboxylate group of an acidic residue (Asp474, Asp467) or an H-bond with the hydroxyl group of Ser471 in an opposing α helix (res. Ala461-Phe476). In the variant simulations, Gln429 cannot form ionic interactions with the acidic residues; however, the carboxamide group can form multiple H-bonds. The H-bonding coordination of the Asn429 side chain varied between the replica simulations. In one simulation, three H-bonds were formed simultaneously with the Asp467 side chain, the backbone carbonyl group of Asn426, and the amide group of Met430 at the end of the same α helix. The residue swap could affect the tertiary structure assembly during folding due to weaker bond formation, but no large-scale negative effects were seen during the simulations.

AISynGAP1 missense variant H481Y is listed in ClinVar as benign (ClinVar ID 1543764.0) and is present in the gnomAD database (gnomAD ID 6‑33438473‑C‑T). Prediction tools that classify the variant as benign include REVEL, Rosetta, premPS, SIFT, FATHMM, and AlphaMissense‑Optimized. Those that predict pathogenicity are PROVEAN, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, ESM1b, and AlphaMissense‑Default. FoldX and Foldetta report uncertain stability effects. High‑accuracy assessments show AlphaMissense‑Optimized as benign, the SGM Consensus (majority vote from AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) as likely pathogenic, and Foldetta as uncertain. Taking all available evidence together, the variant is most likely benign, which is consistent with its ClinVar benign annotation.

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.

High‑accuracy assessments give AlphaMissense‑Optimized benign, SGM consensus pathogenic, and Foldetta uncertain. Because the high‑accuracy predictions are divided and the overall tool set is evenly split, there is no definitive evidence for pathogenicity or benignity. Thus, the variant is most likely inconclusive, and this lack of consensus does not contradict the ClinVar uncertain status.

Functional prediction tools that agree on a benign effect include REVEL, PROVEAN, SIFT, ESM1b, AlphaMissense‑Default, and AlphaMissense‑Optimized. Tools that predict a pathogenic effect are polyPhen‑2 HumDiv, polyPhen‑2 HumVar, and FATHMM. The SGM‑Consensus, derived from a majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN, reports a likely benign outcome. High‑accuracy assessments show AlphaMissense‑Optimized as benign, SGM‑Consensus as likely benign, and Foldetta (combining FoldX‑MD and Rosetta outputs) as uncertain. No other high‑confidence stability predictions are available. Overall, the consensus of the available predictions indicates that the variant is most likely benign, which aligns with its ClinVar classification and does not contradict the reported status.

Functional prediction tools show a split assessment: benign predictions come from REVEL and FATHMM, whereas pathogenic predictions are reported by PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, and AlphaMissense‑Default. High‑accuracy analyses further refine the picture: AlphaMissense‑Optimized classifies the variant as benign, whereas the SGM Consensus—derived from a majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN—deems it likely pathogenic. No Foldetta stability assessment is available for this residue. Overall, the majority of computational evidence points toward a pathogenic effect, which is consistent with the ClinVar designation of uncertain significance rather than a definitive benign classification.

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.

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.

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.

Overall, the balance of evidence favors a pathogenic interpretation, which does not contradict the current ClinVar designation of Uncertain.

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.

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.

High‑accuracy assessment shows AlphaMissense‑Optimized predicts a benign outcome; the SGM Consensus, derived from a majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN, is inconclusive, and Foldetta results are unavailable. Consequently, the overall computational evidence leans toward a pathogenic interpretation, but the presence of a single high‑accuracy benign prediction and the inconclusive SGM Consensus leave the variant’s effect uncertain. This computational assessment does not contradict the ClinVar status, which remains Uncertain.

High‑accuracy assessments reinforce the pathogenic prediction: AlphaMissense‑Optimized reports a benign outcome, but the SGM‑Consensus (derived from a majority of pathogenic calls among AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN) and Foldetta (combining pathogenic FoldX with uncertain Rosetta) both predict pathogenicity. Overall, the preponderance of evidence supports a likely pathogenic classification, which does not conflict with the ClinVar uncertain status.

Arg259-Arg272), forms salt bridges with the carboxylate groups of Asp684 at the end of an α helix (res. Ile683-Gln702, GAP domain) and Asp261 on the same β strand. The Arg259 side chain also frequently forms hydrogen bonds with the backbone carbonyl groups of Ser257, Asn256, and Asp255. In the variant simulations, the indole ring of the Trp259 side chain cannot form salt bridges or maintain hydrogen bonding with the carboxylate group of Asp684 or other nearby residues. Notably, the amino group of the Lys254 side chain maintains a salt bridge with Asp684 and Glu244 throughout the variant simulations, while it forms a cation-π bond with the indole ring of Trp259 in the variant. This salt bridge is not maintained in the WT simulations. Additionally, the partially or loosely α helical conformation of a lysine-containing loop (res. Lys251-Ser257), which extends to a nearby α helix (res. Met414-Asn426), could be stabilized due to the residue swap. Moreover, the bulky size of the Trp259 side chain requires nearby residues to adjust their positioning to accommodate the introduced residue, weakening the tertiary structure assembly between the C2, PH, and GAP domains. The residue swap potentially causes more severe effects during protein folding or for the SynGAP-membrane interaction than the solvent-only simulations imply.

Arg259-Arg272), is stably maintained in an upright and outward position via stacking with the indole ring of the Trp362 side chain in another β strand (res. Thr359-Pro364). 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.

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 R475W is listed in ClinVar with an “Uncertain” status and is present in gnomAD (variant ID 6‑33438455‑C‑T). 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 missense variant Y497C is listed in ClinVar with an “Uncertain” status and is not reported in gnomAD. 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.

Leu489-Glu519) within the inter-helix space of four α-helices (res. Leu489-Ile501, res. Val441-Ser457, res. Arg563-Glu578, res. Ala461-Val473). 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.

AISynGAP1 missense variant A541G is listed in ClinVar with an uncertain significance and is present in gnomAD (ID 6‑33438865‑C‑G). Prediction tools that agree on a benign effect include REVEL, PROVEAN, SIFT, and AlphaMissense‑Optimized. Those that predict a pathogenic effect are polyPhen‑2 HumDiv, polyPhen‑2 HumVar, and FATHMM. The remaining tools (FoldX, Rosetta, Foldetta, premPS, AlphaMissense‑Default, and ESM1b) return uncertain or inconclusive results. High‑accuracy assessments show AlphaMissense‑Optimized as benign, the SGM Consensus (majority vote from AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) is inconclusive, and Foldetta is also inconclusive. Overall, the balance of evidence leans toward a benign impact, which does not contradict the ClinVar uncertain status.

Ala533-Val560). The methyl group of Ala541 is on the surface and does not form any interactions. Glycine, known as an “α-helix breaker,” weakens the integrity of the helix. Indeed, in the variant simulations, the hydrogen bond formation between Gly541 and the backbone carbonyl of Ala537 is disrupted.
