Functional prediction tools show a split opinion: benign predictions come from REVEL, PROVEAN, ESM1b, and FATHMM, whereas pathogenic predictions are reported by polyPhen‑2 HumDiv, polyPhen‑2 HumVar, SIFT, and AlphaMissense‑Default. The SGM‑Consensus, which aggregates AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN, is classified as Likely Benign. High‑accuracy assessments further support a benign interpretation: AlphaMissense‑Optimized predicts benign, and the SGM‑Consensus (majority vote) also favors benign. No Foldetta stability analysis is available for this variant.

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 valine are rarely tolerated. Although no negative structural effects are observed in the variant simulations, Val373 may exert drastic effects on the SynGAP-membrane complex dynamics and stability. However, since the effect on the Gly-rich Ω loop dynamics can only be studied through the SynGAP-membrane complex, no definite conclusions can be drawn. | |||||||||

Ala399-Ile411), forms a salt bridge with the carboxylate group of the Glu446 side chain from an opposing α helix (res. Val441-Ser457) in the GAP domain. The positively charged Arg405 side chain also stacks with the aromatic ring of the Phe358 side chain from a loop preceding the β strand (res. Thr359-Thr366), which could assist in maintaining the anti-parallel strand arrangement.In the variant simulations, the thiol-containing side chain of Cys405 is neutral and smaller compared to the arginine side chain. The lack of Arg405-Phe358 stacking affects the loop structure, causing it to assume a β strand form—an effect that could be exacerbated during protein folding. Moreover, the inability of Cys405 to form a salt bridge with Glu446 could affect the tertiary structure assembly, although this is not apparent based on the variant simulations. | |||||||

All other evaluated algorithms—REVEL, FoldX, Foldetta, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, FATHMM, AlphaMissense‑Default, AlphaMissense‑Optimized, and the SGM‑Consensus—classify the variant as pathogenic or likely pathogenic, while Rosetta remains inconclusive. High‑accuracy assessments further support a deleterious impact: AlphaMissense‑Optimized predicts pathogenic; the SGM‑Consensus (majority vote from AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) indicates likely pathogenic; and Foldetta, which integrates FoldX‑MD and Rosetta outputs, also predicts pathogenic. **Thus, the variant is most likely pathogenic based on the collective predictions, which does not contradict the ClinVar uncertain status.** Disclaimer: This summary was generated using AI and should be interpreted alongside expert review. | Likely Pathogenic | GAP | Conflicting | 2 | 6-33440838-C-T | 6 | 3.72e-6 | -10.805 | Likely Pathogenic | 0.972 | Likely Pathogenic | Likely Pathogenic | 0.633 | Likely Pathogenic | 2.94 | Destabilizing | 0.0 | 1.49 | Ambiguous | 2.22 | Destabilizing | -0.03 | Likely Benign | -7.96 | Deleterious | 1.000 | Probably Damaging | 1.000 | Probably Damaging | 2.41 | Pathogenic | 0.00 | Affected | 3.37 | 35 | -4 | -3 | 7.0 | -53.05 | 230.7 | 97.9 | -0.1 | 0.0 | -0.3 | 0.4 | X | X | Potentially Pathogenic | The guanidinium group of Arg596, located in an α helix (res. Glu582-Met603), forms a salt bridge with the carboxylate group of Glu495 from another α helix (res. Leu489-Glu519). 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 thiol group of the Cys596 side chain is unable to form salt bridges or any of the hydrogen bonds that the Arg596 side chain can. 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. | |||||||

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 report benign include polyPhen‑2 HumVar, FATHMM, AlphaMissense‑Default, and AlphaMissense‑Optimized. Tools that predict pathogenicity are REVEL, PROVEAN, polyPhen‑2 HumDiv, SIFT, and ESM1b. Four tools give uncertain or inconclusive results: FoldX, Rosetta, Foldetta, and premPS. The SGM Consensus, derived from a majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN, is inconclusive because the votes are evenly split. High‑accuracy assessments show AlphaMissense‑Optimized as benign, Foldetta as uncertain, and the SGM Consensus as unavailable. Consequently, the overall prediction profile is mixed, but the most reliable high‑accuracy evidence points toward a benign effect. Therefore, the variant is most likely benign, which aligns with its ClinVar classification and does not contradict the reported status.

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 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. However, since the effects on Gly-rich Ω loop dynamics can only be studied through the SynGAP-membrane complex, no definite conclusions can be drawn. | |||||||||

| c.1286G>A | R429Q 2D 3DClick to see structure in 3D Viewer AIThe SynGAP1 missense variant R429Q is listed in ClinVar with an “Uncertain” status and is present in gnomAD (variant ID 6‑33438191‑G‑A). Functional prediction tools that agree on a benign effect include REVEL, FoldX, Rosetta, Foldetta, PROVEAN, SIFT, FATHMM, AlphaMissense‑Default, and AlphaMissense‑Optimized. Tools that predict a pathogenic effect are polyPhen‑2 HumDiv, polyPhen‑2 HumVar, and ESM1b, while premPS is inconclusive. The high‑accuracy consensus (SGM Consensus) – a majority vote among AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN – yields a “Likely Benign” result. AlphaMissense‑Optimized itself predicts benign, and Foldetta (combining FoldX‑MD and Rosetta outputs) also predicts benign. 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. | ||||||||

Glu617-Asn635), forms hydrogen bonds with Gln631 on the same α helix and with the hydroxyl side chain of Ser590 on an opposing α helix (res. Glu582-Met603).In the variant simulations, the side chain of Ser635 is shorter than asparagine and thus prefers to hydrogen bond with the carbonyl group of Gln631 on the same helix and, to a lesser extent, with Ser590 compared to Asn635 in the WT. Ser635 forms hydrogen bonds with the backbone atoms of the same helix, which may destabilize the helix, although this is not clearly evident in the simulations. The weakening of the hydrogen bond between Ser635 and Ser590 in the variant may also weaken the tertiary structure assembly between the helices.Additionally, Asn635 is at the GTPase interface. However, the implication of the residue swap on the complex formation with the GTPase cannot be investigated using solvent-only simulations. | |||||||||

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. | |||||||||

In the variant simulations, the methyl group of the Ala305 side chain cannot hydrogen bond with either of the acidic residues, which could weaken the integrity of the tertiary structure and the β hairpin loop. Indeed, the guanidinium group of Arg299 does not acquire its central hairpin loop position due to the residue swap.β hairpins are potential nucleation sites during the initial stages of protein folding, so even minor changes in them could be significant. Due to its location near the membrane surface, the residue swap could also affect the C2 loop dynamics and SynGAP-membrane association.

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 | |||||||

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. | |||||||||

Pro364- Pro398) between two anti-parallel β sheet strands (res. Thr359-Pro364, res. Ala399-Ile411). 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. Thus, Ser370 in the variant is potentially tolerated in the Ω loop. However, since the effect on the Gly-rich Ω loop dynamics can only be well-studied through the SynGAP-membrane complex, no definite conclusions can be withdrawn. | |||||||||

Functional prediction tools largely agree on a deleterious effect: REVEL, FoldX, premPS, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, FATHMM, AlphaMissense‑Default, and the SGM‑Consensus all report pathogenicity, while only Rosetta predicts a benign outcome. Two tools are inconclusive: AlphaMissense‑Optimized and Foldetta. High‑accuracy assessments show AlphaMissense‑Optimized as uncertain, SGM‑Consensus (derived from the four pathogenic votes) as pathogenic, and Foldetta as uncertain.

Glu582-Met603), forms a salt bridge with the carboxylate group of Glu495 from another α helix (res. Leu489-Glu519). 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. | |||||||

Functional prediction tools that agree on a benign effect include only FATHMM, whereas the remaining tools—REVEL, premPS, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, and AlphaMissense‑Default—consistently predict a pathogenic impact. High‑accuracy assessments show AlphaMissense‑Optimized as uncertain, SGM‑Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) as pathogenic, and Foldetta (combining FoldX‑MD and Rosetta outputs) as uncertain. No evidence from FoldX, Rosetta, or Foldetta supports a benign outcome. Overall, the preponderance of predictions indicates a likely pathogenic effect, which contradicts the benign classification reported in ClinVar.

Glu617-Asn635), forms a salt bridge with Glu525 in a nearby loop and stacks with Leu635. In the variant simulations, the carboxamide side chain of Gln621, which can act as both a hydrogen bond acceptor and donor, also stacks with Leu635 but can only sporadically hydrogen bond with Glu525.Accordingly, the residue swap could affect the tertiary structure integrity by disrupting the salt bridge formation. Additionally, due to its location at the GAP-Ras interface, the residue swap could impact the complex formation with the GTPase, but this cannot be investigated using solvent-only simulations. | |||||||

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. Met672 can only form a hydrogen bond with the amino group of the Lys566 side chain via its backbone carbonyl group. Nevertheless, the Lys566-Glu666 salt bridge forms intermittently. This is possible because Asn669 keeps the carboxylate group of Glu666 in the vicinity through hydrogen bonding, and the hydrophobic side chain of Met stays mostly rotated away from the salt bridge. Consequently, no drastic disruption of the hydrogen-bond network that keeps the loop close to the helices occurs in the variant simulations. | ||||||||

Gly341-Pro349), faces outward in the C2 domain. This phenol ring contributes to a triple tyrosine stack (Tyr342, Tyr328, and Tyr281) that links together three anti-parallel β sheet strands. Additionally, it shields Gly344 from the solvent, reducing its exposure and providing stability for the β-sandwich. This motif also contributes to a twist formation in the β sheet.In the variant simulations, the Cys342 side chain cannot participate in the stack formation. Instead, its thiol group forms a hydrogen bond with the backbone carbonyl group of Leu327. Although these changes in surface interactions could weaken the characteristic twist that strengthens the β sheet fold, no major structural effects are observed in the variant simulations. The residue swap could also affect the SynGAP-membrane association; however, this phenomenon cannot be addressed using solvent-only simulations. Notably, the thiol group of cysteine is not a particularly strong hydrogen-bonding partner, which could mitigate the negative effects of the residue swap. | |||||||||

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, Val387 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. | |||||||||

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. | ||||||||

| c.1888A>G | I630V 2D 3DClick to see structure in 3D Viewer AIThe SynGAP1 missense variant I630V is listed in ClinVar as Benign and is present in gnomAD (variant ID 6‑33440940‑A‑G). Functional prediction tools that agree on a benign effect include REVEL, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, AlphaMissense‑Default, and AlphaMissense‑Optimized. Only FATHMM predicts a pathogenic outcome; all other tools (FoldX, Rosetta, Foldetta, premPS, ESM1b) return uncertain or inconclusive results. The high‑accuracy consensus (SGM Consensus) derived from AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN yields a benign majority (2 benign vs. 1 pathogenic, 1 uncertain). AlphaMissense‑Optimized also predicts benign. Foldetta, which integrates FoldX‑MD and Rosetta stability calculations, is uncertain. Taken together, the overwhelming majority of predictions support a benign effect, and this conclusion aligns with the ClinVar designation. Thus, the variant is most likely benign, with no contradiction to the ClinVar status.
