| c.1436G>C | R479P 2D  3DClick to see structure in 3D Viewer AIClinVar lists the SynGAP1 R479P variant as Uncertain, and it is not reported in gnomAD. Prediction tools that agree on a benign effect include REVEL, SIFT, and FATHMM. Those that predict a pathogenic effect are FoldX, Rosetta, PROVEAN, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, AlphaMissense‑Default, and ESM1b. Predictions that are inconclusive are AlphaMissense‑Optimized and premPS. High‑accuracy assessments show AlphaMissense‑Optimized as uncertain, the SGM Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) as pathogenic, and Foldetta (combining FoldX‑MD and Rosetta) as pathogenic. Overall, the majority of tools and the high‑accuracy methods support a pathogenic classification, which is in contrast to the ClinVar designation of uncertain significance.

Prediction tools that agree on a benign effect include REVEL, FoldX, Rosetta, Foldetta, premPS, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, AlphaMissense‑Default, AlphaMissense‑Optimized, and the SGM Consensus (majority vote). Only FATHMM predicts a pathogenic outcome. High‑accuracy assessments—AlphaMissense‑Optimized, the SGM Consensus, and Foldetta (combining FoldX‑MD and Rosetta outputs)—all indicate a benign impact. No prediction or folding‑stability result is missing or inconclusive. Based on the collective evidence, the variant is most likely benign, and this conclusion is consistent with its ClinVar status.

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

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. | ||||||||

Functional prediction tools cluster into two groups: benign predictions come from FoldX, SIFT, and AlphaMissense‑Optimized; pathogenic predictions arise from REVEL, PolyPhen‑2 (HumDiv and HumVar), ESM1b, FATHMM, AlphaMissense‑Default, PROVEAN, and the SGM Consensus score (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN). The high‑accuracy AlphaMissense‑Optimized predicts benign, whereas the SGM Consensus predicts likely pathogenic; Foldetta, a folding‑stability method combining FoldX‑MD and Rosetta outputs, returns an uncertain result and is therefore not factored into the consensus. Overall, the majority of evidence supports a pathogenic effect, which contrasts with the ClinVar uncertain classification.

Ala461–Phe476), interacts with hydrophobic residues (e.g., Trp572, Leu588, Met470) in an inter-helix space formed by two other α helices (res. Glu582–Ser604, res. Arg563–Gly580). In the variant simulations, Asp469 introduces a negatively charged and bulky side chain into the hydrophobic niche. Consequently, the side chain of Asp469 rotates outward, allowing the carboxylate group to form a salt bridge with the guanidinium group of Arg575 on the protein surface. This interaction affects the continuity of the parent α helix (Ala461–Phe476). Due to the importance of hydrophobic packing, the structural effects could be more pronounced during actual protein folding. | ||||||||||

Met289-Pro298, res. Thr305-Asn315), points outward from the β hairpin loop, and its backbone atoms do not participate in the loop formation in the WT simulations. In the variant simulations, the hydroxyl group of the Thr301 side chain also mostly points outward; however, the guanidinium group of Arg299 is moved away from its central hairpin loop position.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.

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.

Prediction tools that uniformly indicate a benign effect include REVEL, FoldX, Rosetta, Foldetta, premPS, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, AlphaMissense‑Default, and AlphaMissense‑Optimized. Only FATHMM predicts a pathogenic outcome. The SGM‑Consensus, which aggregates the majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN, resolves to “Likely Benign” (3 benign vs. 1 pathogenic). High‑accuracy assessments are consistent: AlphaMissense‑Optimized is benign; the SGM‑Consensus is likely benign; and Foldetta, combining FoldX‑MD and Rosetta outputs, is benign. Overall, the collective evidence strongly supports a benign classification, and this does not contradict the ClinVar “Uncertain” designation.

Met414-Glu436), packs against hydrophobic residues in the interhelix area of the GAP domain (e.g., Leu689, Leu714, Leu717, Leu718). In the variant simulations, the iso-butyl side chain of Leu420 also packs into the hydrophobic inter-helix niche, but due to its smaller size, the resulting steric interactions are not as favorable as with phenylalanine. In short, the residue swap does not cause severe effects on the protein structure based on the variant simulations. | |||||||||||

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. | ||||||||

The backbone carbonyl group of Ser296 also hydrogen bonds with the guanidinium group of Arg279 in another nearby β strand (res. Arg279-Cys285). In the variant simulations, the methyl group of the Ala296 side chain cannot hydrogen bond with Asp330, causing the carboxylate group positioning to fluctuate more than in the WT simulations.Although the residue swap does not seem to affect the anti-parallel β sheet assembly during the simulations, it is possible that the Ser296-Asp330 hydrogen bond plays a crucial role in maintaining the C2 domain fold. Notably, because Ser296 is located near the membrane interface, the potential effect of the residue swap on the SynGAP-membrane association cannot be addressed by solvent-only simulations. | |||||||||||

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. | |||||||||

Ile205-Pro208), is replaced by another acidic residue, glutamate. The carboxylate groups of both Asp201 and Glu201 side chains form hydrogen bonds with the hydroxyl group of Ser221 in the simulations. 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. | ||||||||
| c.819G>T | E273D 2D 3DClick to see structure in 3D Viewer AIThe SynGAP1 missense variant E273D is listed in ClinVar as Benign (ClinVar ID 1471608.0) and is present in gnomAD (variant ID 6‑33437724‑G‑T). Prediction tools that agree on a benign effect include REVEL, FoldX, Rosetta, Foldetta, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, AlphaMissense‑Default, and AlphaMissense‑Optimized. Only FATHMM predicts a pathogenic outcome, while premPS is uncertain. The SGM‑Consensus, derived from a majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN, is Likely Benign. High‑accuracy assessments are consistent: AlphaMissense‑Optimized predicts benign, the SGM‑Consensus (majority vote) is benign, and Foldetta (combining FoldX‑MD and Rosetta outputs) also predicts benign. No prediction contradicts the ClinVar benign status; overall, the evidence strongly supports that E273D is most likely benign.

Glu273-Lys278) that connects two anti-parallel β sheet strands, is replaced with another negatively charged residue, aspartate. Because the C2 domain loop faces the membrane surface, the potentially crucial role of the carboxylate group of Glu273 or Asp273 on SynGAP-membrane association cannot be fully explored via solvent-only simulations.As a minor note, the neighboring residue Arg272, which stacks with the indole ring of the Trp362 side chain and directly faces RasGTPase, forms a salt bridge more often with Asp273 than with the non-mutated Glu273 in the simulations. Regardless, due to the similar physicochemical properties of the WT and variant residues at the membrane interface, the residue swap is likely to be well tolerated. | ||||||||
| c.865A>G | M289V 2D 3DClick to see structure in 3D Viewer AISynGAP1 missense variant M289V is reported in ClinVar as Benign (ClinVar ID 2122760.0) and is not present in gnomAD. Functional prediction tools largely agree on a benign effect: REVEL, Rosetta, Foldetta, premPS, PROVEAN, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, SIFT, ESM1b, AlphaMissense‑Default, AlphaMissense‑Optimized, and the SGM‑Consensus all predict benign, while only FATHMM predicts pathogenic. High‑accuracy assessments reinforce the benign consensus: AlphaMissense‑Optimized scores benign; the SGM‑Consensus, derived from a majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN, is benign; and Foldetta, which integrates FoldX‑MD and Rosetta stability outputs, also indicates benign. No prediction or stability result is inconclusive. Overall, the computational evidence strongly supports a benign classification, consistent with the ClinVar status and showing no contradiction.

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