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 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. | |||||||||||

Gly341-Pro349, res. Thr359-Pro364) originating from two different anti-parallel β sheets of the C2 domain. In the WT simulations, the side chain hydroxyl and backbone amide groups of Thr354 form hydrogen bonds with the backbone carbonyl group of Pro349 at the end of the preceding β strand. This arrangement likely stabilizes the α helical section and aids in folding, keeping the short secondary structure element intact in the variant simulations. However, the carboxamide group of the Asn352 side chain does not form hydrogen bonds with the backbone carbonyl group of Pro349. Instead, it packs against the cyclic ring and forms hydrogen bonds with the phenol group of the Tyr363 side chain in the other β strand. | ||||||||

Ala533-Val560) close to the membrane interface. In the WT simulations, the hydroxyl side chain of Ser535 forms hydrogen bonds with nearby residues (e.g., His539, Glu538) without any specific interactions. These hydrogen bonds disrupt the structure of the terminal end of the α-helix (Ala533-Ser535), causing it to weaken or unfold during the WT simulations. In the variant simulations, Thr535, a hydrophilic residue with a hydroxyl group of almost the same size as Ser, interacts more frequently with the preceding loop residues (e.g., Thr532, Cys531) due to its longer side chain. Regardless, the residue swap is tolerated in the simulations with no negative effects. However, due to its location near the SynGAP-membrane interface, the effect of the residue swap cannot be fully addressed using the SynGAP solvent-only simulations. | 10.1016/j.ajhg.2020.11.011 | |||||||

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

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

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. | |||||||||

Functional prediction tools largely agree on a deleterious effect: pathogenic predictions come from SGM‑Consensus, REVEL, FoldX, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, FATHMM, AlphaMissense‑Default, and AlphaMissense‑Optimized.

Ala533-Val560 and res. Arg563-Glu578). The cyclic pyrrolidine side chain of Pro562 hydrophobically packs with other residues in the inter-helix space, such as Leu565, Ile501, and Phe561. In the variant simulations, Leu562 packs more favorably with the nearby hydrophobic residues, and the backbone amide group of Leu562 (absent in proline) does not form any intra-protein hydrogen bonds. However, prolines are well-suited for unstructured regions like loops, and thus, Pro562 in the WT is necessary at the end of the helix to induce a tight turn during folding. Although no negative structural effects are observed during the simulations, the residue swap could potentially cause extensive damage to the protein structure during folding. | 10.1016/j.ajhg.2020.11.011 | |||||||||

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. | ||||||||

Prediction tools that classify the variant as benign include only SIFT, whereas the remaining tools—REVEL, FoldX, Rosetta, PROVEAN, polyPhen‑2 (HumDiv and HumVar), ESM1b, FATHMM, AlphaMissense‑Default, and AlphaMissense‑Optimized—predict it to be pathogenic. The SGM Consensus, derived from a majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN, also indicates likely pathogenic. High‑accuracy assessments further support a deleterious effect: AlphaMissense‑Optimized is pathogenic, the SGM Consensus is likely pathogenic, and Foldetta (combining FoldX‑MD and Rosetta outputs) predicts pathogenicity. No predictions are inconclusive or missing. Overall, the collective evidence points to a pathogenic effect for A541P, which is in contrast to the ClinVar designation of uncertain significance.

Ala533-Val560). The methyl group of Ala541 is on the surface and does not form any interactions. Proline lacks a free backbone amide group, and thus, Pro541 is unable to form a hydrogen bond with the carbonyl group of Ala537 in the variant simulations. Consequently, Pro541 disrupts the continuity of the secondary structure element, causing the α-helix to bend slightly in the variant simulations. | |||||||||||

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.

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. | |||||||

Prediction tools that agree on a benign effect include REVEL, PROVEAN, polyPhen‑2 HumVar, ESM1b, FATHMM, AlphaMissense‑Default, AlphaMissense‑Optimized, and the SGM‑Consensus (majority vote from AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN). Tools that predict a pathogenic effect are polyPhen‑2 HumDiv and SIFT. High‑accuracy methods both support a benign outcome: AlphaMissense‑Optimized is benign, and the SGM‑Consensus (majority vote) is benign; Foldetta results are unavailable.

Functional prediction tools cluster into two groups: benign predictions come from REVEL, SIFT, ESM1b, AlphaMissense‑Default, and AlphaMissense‑Optimized; pathogenic predictions come from PROVEAN, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, and FATHMM. High‑accuracy assessments show AlphaMissense‑Optimized as benign, while the SGM Consensus—derived from a majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN—yields a tie and is therefore inconclusive. Foldetta, which integrates FoldX‑MD and Rosetta stability calculations, has no reported result for this variant. Overall, the balance of evidence (five benign versus four pathogenic predictions) suggests the variant is most likely benign, and this conclusion does not contradict the ClinVar uncertain status.

Thr704-Gly712), which is connected via a tight turn or loop to another α-helix (res. Asp684-Gln702). The hydroxyl side chain of Ser704 occasionally forms a hydrogen bond with the amide group of Ala707. However, in the variant simulations, the carboxamide side chain of Asn704 achieves more lasting and numerous hydrogen-bonding interactions with the residues at the helix end, such as Glu706, Ala707, and Leu708. Consequently, the residue swap could strengthen the α-helix secondary structure integrity at the helix end, which could have either positive or negative effects on its function. | ||||||||

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.

Ser641-Glu666 and res. Leu685-Val699), is involved in a highly coordinated hydrogen-bonding network between residues from two α-helices (res. Ser641-Glu666 and res. Arg563-Glu578) and from the α-α loop itself, such as Lys566, Glu666, and Asn669. 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. | ||||||||||

Ala399-Ile411), hydrophobically packs against hydrophobic residues within the anti-parallel β sheet of the C2 domain (e.g., Ile268, Ala404, Leu325, Leu402). In the variant simulations, the negatively charged carboxylate group of the Glu400 side chain is not suitable for occupying the hydrophobic niche. Consequently, the side chain escapes the center of the C2 domain and interacts with the backbone amide groups of Leu402 in the same β strand and/or Ile269 and Glu270 in a neighboring β strand (res. Arg259-Arg272). This residue swap disrupts the hydrophobic packing and generally has extensive negative effects on the C2 domain structure.

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

Because, the Ω loop is assumed to be directly interacting with the membrane, it is only seen to move arbitrarily throughout the WT solvent simulations. The Ω loop is potentially playing a crucial loop in the SynGAP-membrane complex association, stability and dynamics, regardless, this aspect cannot be addressed through the solvent simulations only. The Ω-loops are known to have a major role in protein functions that requires flexibility and thus, they are rich in glycines, prolines and to a lesser extent, hydrophilic residues to ensure maximum flexibility.

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. | ||||||

Prediction tools that agree on a pathogenic effect include REVEL, FoldX, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, FATHMM, AlphaMissense‑Default, and AlphaMissense‑Optimized. Tools with uncertain or inconclusive results are Rosetta, Foldetta, and premPS. High‑accuracy assessments show AlphaMissense‑Optimized predicts pathogenicity, the SGM Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) indicates likely pathogenic, and Foldetta yields an uncertain stability change. Overall, the majority of evidence points to a pathogenic effect, which does not contradict the ClinVar uncertain 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 indole ring of the Trp573 side chain is unable to maintain the same level of coordination as the positively charged Arg573 side chain. Indeed, Trp573 is seen hydrogen bonding only briefly with the carboxylate group of Glu582. 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. | ||||||||||

Among the available in‑silico predictors, the majority (REVEL, FoldX, PROVEAN, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, ESM1b, FATHMM, AlphaMissense‑Default) indicate a pathogenic effect, whereas only SIFT predicts a benign outcome. Predictions that are inconclusive or uncertain include Rosetta, Foldetta, premPS, AlphaMissense‑Optimized, and the SGM‑Consensus (which is derived from the pathogenic majority of the four contributing tools). High‑accuracy assessments show AlphaMissense‑Optimized as uncertain, SGM‑Consensus as pathogenic (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN), and Foldetta as uncertain (combining a pathogenic FoldX result with an uncertain Rosetta result).

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. | ||||||||||

Glu582-Met603), packs against hydrophobic residues (e.g., Ile483, Phe484) of an opposing partially helical loop (res. Phe476-Asn487).In the variant simulations, the hydroxyl group of Thr591 can form hydrogen bonds with the backbone carbonyl of Ile843 in the opposing loop or the backbone carbonyl group of Arg587. These interactions could either reinforce the tertiary assembly or weaken the α helix unity. Additionally, the Thr591 side chain can hydrogen bond with the guanidinium group of the Arg587 side chain, potentially strengthening the α helix unity.Overall, the residue swap does not seem to cause any major negative effects on the protein structure. | ||||||||

c.2818G>A | G940S 2D ![]() AIThe SynGAP1 missense variant G940S is listed in ClinVar with an “Uncertain” status and is present in gnomAD (ID 6‑33443370‑G‑A). All available in silico predictors agree on a benign effect: REVEL, PROVEAN, PolyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, FATHMM, AlphaMissense‑Default, and AlphaMissense‑Optimized all return benign scores, and the SGM‑Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN) is “Likely Benign.” High‑accuracy tools reinforce this view: AlphaMissense‑Optimized predicts benign, and the SGM‑Consensus likewise indicates a benign outcome. Foldetta, a protein‑folding stability method combining FoldX‑MD and Rosetta, has no reported result for this variant, so its status is unavailable. Overall, the computational evidence strongly supports a benign classification, which does not contradict the ClinVar “Uncertain” designation.

c.2830G>A | G944S 2D ![]() AIThe SynGAP1 missense variant G944S is listed in ClinVar as a benign alteration (ClinVar ID 833552.0) and is present in the gnomAD database (gnomAD ID 6‑33443382‑G‑A). Prediction tools that agree on a benign effect include REVEL, PROVEAN, polyPhen‑2 (HumDiv and HumVar), ESM1b, FATHMM, AlphaMissense‑Default, AlphaMissense‑Optimized, and the SGM‑Consensus (majority vote from AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN). Only SIFT predicts a pathogenic outcome. High‑accuracy assessments show AlphaMissense‑Optimized as benign and the SGM‑Consensus as likely benign; Foldetta results are not available for this variant. Overall, the majority of computational evidence supports a benign classification, which aligns with the ClinVar status and does not contradict it.

c.2845G>A | G949S 2D ![]() AIThe SynGAP1 missense variant G949S is listed in ClinVar as a benign alteration (ClinVar ID 212352.0) and is present in the gnomAD database (6‑33443397‑G‑A). Prediction tools that agree on a benign effect include REVEL, PROVEAN, polyPhen‑2 HumVar, ESM1b, AlphaMissense‑Default, AlphaMissense‑Optimized, and the SGM‑Consensus (majority vote). Tools that predict a pathogenic effect are polyPhen‑2 HumDiv, SIFT, and FATHMM. High‑accuracy assessments show AlphaMissense‑Optimized as benign, the SGM‑Consensus (derived from AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN) as likely benign, and Foldetta results are unavailable. Overall, the majority of evidence points to a benign impact, aligning with the ClinVar classification and indicating no contradiction.
