c.1003C>T	R335C 2D 3DClick to see structure in 3D Viewer AISynGAP1 missense variant R335C is listed in ClinVar with an uncertain significance (ClinVar ID 2835865.0) and is present in gnomAD (ID 6‑33437908‑C‑T). Functional prediction tools cluster into two groups: benign predictions come from REVEL and premPS, whereas pathogenic predictions are made by PROVEAN, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, SIFT, ESM1b, FATHMM, and AlphaMissense‑Default. Predictions that are inconclusive are AlphaMissense‑Optimized, FoldX, Rosetta, and Foldetta. High‑accuracy assessments show AlphaMissense‑Optimized as uncertain, the SGM Consensus (derived from the unanimous pathogenic vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN) as pathogenic, and Foldetta as uncertain. Overall, the majority of evidence points to a pathogenic effect. This conclusion aligns with the ClinVar designation of uncertain significance, which does not contradict the prediction that the variant is most likely pathogenic.

c.1004G>A	R335H 2D 3DClick to see structure in 3D Viewer AISynGAP1 missense variant R335H is listed in ClinVar with an uncertain significance and is present in gnomAD (variant ID 6-33437909‑G‑A). Functional prediction tools cluster into two groups: benign predictions come from REVEL, Rosetta, and Foldetta, while pathogenic predictions are made by PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, FATHMM, and AlphaMissense‑Default. Uncertain results are reported by FoldX, premPS, and AlphaMissense‑Optimized. High‑accuracy assessments show that the SGM Consensus—derived from a majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN—labels the variant as pathogenic, whereas Foldetta, a protein‑folding stability method combining FoldX‑MD and Rosetta outputs, predicts a benign effect. Overall, the preponderance of evidence points to a pathogenic impact, which does not contradict the ClinVar uncertain status.

Ala322-Asp330, res. Gly341-Pro349), faces the post-synaptic inner membrane surface. In the WT simulations, the Arg335 side chain dynamically forms salt bridges with the carboxylate groups of Asp322, Asp338, and Asp616. In contrast, the imidazole ring of His335, which is not double protonated and thus not positively charged in the variant simulations, continues to move dynamically without forming any lasting or strong interactions. Importantly, the positively charged arginine residues of the C2 domain are ideal membrane anchors for ensuring SynGAP-membrane association. However, this phenomenon cannot be addressed using solvent-only simulations.
c.103G>A	V35I 2D AIThe SynGAP1 missense variant V35I is listed in ClinVar with an “Uncertain” status and is present in gnomAD (ID 6‑33423512‑G‑A). Prediction tools that agree on a benign effect include REVEL, PROVEAN, polyPhen‑2 HumVar, ESM1b, FATHMM, AlphaMissense‑Default, and AlphaMissense‑Optimized. Tools that predict a pathogenic effect are polyPhen‑2 HumDiv and SIFT. High‑accuracy assessments show AlphaMissense‑Optimized as benign, and the SGM Consensus (majority vote from AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN) also indicates a benign outcome. No Foldetta stability data are available. Overall, the majority of evidence points to a benign impact, and this is consistent with the ClinVar “Uncertain” classification rather than contradicting it.

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 from 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 points to a benign effect, aligning with the ClinVar designation of uncertain significance.

c.1042G>A	V348M 2D 3DClick to see structure in 3D Viewer AISynGAP1 variant V348M is listed in ClinVar with an uncertain significance and is not reported in gnomAD. Functional prediction tools that report a clear outcome fall into two groups: benign calls come from REVEL, Foldetta, PROVEAN, and AlphaMissense‑Optimized; pathogenic calls come from polyPhen‑2 (HumDiv and HumVar), SIFT, and FATHMM. The remaining tools (FoldX, Rosetta, premPS, AlphaMissense‑Default, ESM1b) give uncertain results, and the SGM Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) is unavailable due to no majority. High‑accuracy methods specifically show AlphaMissense‑Optimized as benign, Foldetta as benign, and the SGM Consensus is not available. With four benign and four pathogenic predictions, the evidence is evenly split, providing no definitive direction. Therefore, the variant is not clearly benign or pathogenic based on current predictions, and this lack of consensus does not contradict its ClinVar uncertain status.

Gly341-Pro349), packs against multiple hydrophobic C2 domain residues (e.g., Leu353, Leu323, Leu402). In the variant simulations, the thioether side chain of Met348 can form similar interactions as valine due to its comparable hydrophobic profile. In fact, the thioether group of methionine can even stack favorably with the phenol ring of Tyr363 in the anti-parallel β sheet strand (res. Ala399-Ile411). Overall, the residue swap does not appear to cause negative effects on the protein structure based on the simulations.
c.1045C>T	P349S 2D 3DClick to see structure in 3D Viewer AIThe SynGAP1 P349S missense variant is listed in ClinVar with an “Uncertain” status and is not reported in gnomAD. Prediction tools that agree on a benign effect include REVEL, SIFT, AlphaMissense‑Default, and AlphaMissense‑Optimized. Those that predict a pathogenic impact are Rosetta, PROVEAN, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, and FATHMM. Predictions that are inconclusive or uncertain are FoldX, ESM1b, and premPS. High‑accuracy assessments show AlphaMissense‑Optimized as benign, the SGM Consensus (majority vote from AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) as pathogenic, and Foldetta (combining FoldX‑MD and Rosetta outputs) as pathogenic. Overall, the majority of tools, including the high‑accuracy methods, predict a pathogenic effect. Thus, the variant is most likely pathogenic, which does not contradict its current ClinVar “Uncertain” classification.

Gly341-Pro349), allows the strand to end and make a tight turn before a short α helical section within a loop connecting to another β strand (res. Thr359-Pro364). In the variant simulations, the hydroxyl group of Ser349 forms a hydrogen bond with the backbone amide group of Ala351 in the short helical section. Conversely, the backbone amide group of Ser349 (absent in proline) does not form any intra-protein hydrogen bonds. However, the β strand end connects to the α helical section in a more stable and consistent manner compared to the WT. Although the residue swap does not cause major adverse effects on the protein structure in the simulations, it is possible that the tight turn at the β strand end could not be created during folding without the presence of proline.
c.1055C>A	T352N 2D 3DClick to see structure in 3D Viewer AIThe SynGAP1 missense variant T352N is listed in ClinVar as Benign (ClinVar ID 590151.0) and is present in the gnomAD database (gnomAD ID 6‑33437960‑C‑A). Across the broad panel of in‑silico predictors, 13 tools (REVEL, FoldX, Rosetta, Foldetta, premPS, PROVEAN, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, SIFT, ESM1b, AlphaMissense‑Default, AlphaMissense‑Optimized, and the SGM‑Consensus) uniformly report a benign effect, whereas only FATHMM predicts pathogenicity. High‑accuracy assessments reinforce the benign consensus: AlphaMissense‑Optimized is benign; the SGM‑Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) is benign; and Foldetta, which integrates FoldX‑MD and Rosetta stability outputs, is also benign. No predictions or stability analyses are missing or inconclusive. Overall, the computational evidence strongly supports a benign classification, consistent with the ClinVar status.

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.
c.1058T>C	L353P 2D 3DClick to see structure in 3D Viewer AIThe SynGAP1 missense variant L353P is listed in ClinVar with an uncertain significance and is not reported in gnomAD. Functional prediction tools show a strong bias toward pathogenicity: REVEL predicts benign, whereas FoldX, Rosetta, premPS, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, FATHMM, and AlphaMissense‑Default all predict pathogenic. Two tools report uncertainty: ESM1b and AlphaMissense‑Optimized. High‑accuracy assessments further support a deleterious effect: AlphaMissense‑Optimized is inconclusive, SGM‑Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) predicts pathogenic, and Foldetta (combining FoldX‑MD and Rosetta outputs) also predicts pathogenic. Overall, the majority of evidence points to a pathogenic impact, which is consistent with the ClinVar designation of uncertain significance but leans toward pathogenicity rather than benign. Thus, the variant is most likely pathogenic, and this prediction does not contradict the ClinVar status.

Functional prediction tools cluster into two groups: benign predictions from REVEL and AlphaMissense‑Optimized, and pathogenic predictions from PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, FATHMM, AlphaMissense‑Default, and the SGM‑Consensus score. Uncertain results are reported by FoldX, Rosetta, Foldetta, and premPS. 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 evidence points to a pathogenic effect, contradicting the ClinVar benign classification.

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.
c.1067G>A	R356H 2D 3DClick to see structure in 3D Viewer AISynGAP1 missense variant R356H is recorded in ClinVar as benign (ClinVar ID 2984966.0) and is present in the gnomAD database (6‑33437972‑G‑A).

Functional prediction tools largely agree that the substitution is benign: REVEL, PROVEAN, polyPhen‑2 (HumDiv and HumVar), ESM1b, FATHMM, AlphaMissense‑Default, and AlphaMissense‑Optimized all report a benign effect. Only SIFT predicts a pathogenic outcome. High‑accuracy assessments reinforce the benign consensus: AlphaMissense‑Optimized is benign, and the SGM Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN) is labeled Likely Benign.

All other evaluated algorithms—FoldX, Rosetta, Foldetta, SGM‑Consensus, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, FATHMM, AlphaMissense‑Default, and AlphaMissense‑Optimized—predict a pathogenic impact.

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.

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 so they are rich in glycine residues, prolines, and to a lesser extent, small hydrophilic residues to ensure maximum flexibility. Thus, the variant’s Glu390 may not be as well tolerated in the Ω loop. Additionally, the carboxylate group of Glu390 occasionally forms H-bonds with other loop residues in the variant simulations. The interaction between the acidic carboxylate side chain and the acidic membrane lipids may further influence the SynGAP-membrane complex. However, 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.

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.

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.

In the variant simulations, the positively charged guanidinium group of the Arg402 side chain is not suitable for the hydrophobic niche. Consequently, the side chain moves outward from the hydrophobic C2 domain core and stacks with the phenol ring of Tyr363 or forms H-bonds with the carboxamide group of the Gln361 side chain in the β sheet strand (res.

The SGM consensus, which aggregates AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN, yields a pathogenic majority. 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.

The backbone amide group of Glu419 does not form H-bonds, resulting in a slight bend in the α helix. Thus, although glycine is known as an “α helix breaker,” the residue swap does not disrupt the continuity or integrity of the α helix. However, because Gly419 cannot form a salt bridge with the guanidinium group of the Arg716 side chain, the C2-GAP domain tertiary structure could be compromised during folding.

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.
c.1260T>G	F420L 2D 3DClick to see structure in 3D Viewer AIThe SynGAP1 missense variant F420L is listed in ClinVar (ID 1397885.0) with an “Uncertain” clinical significance and is not reported in gnomAD. Functional prediction tools that agree on a benign effect include REVEL, polyPhen‑2 (HumDiv and HumVar), SIFT, and FATHMM. Those that predict a pathogenic effect comprise premPS, PROVEAN, ESM1b, AlphaMissense‑Default, AlphaMissense‑Optimized, and the SGM Consensus (majority vote from AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN). Stability‑based methods (FoldX, Rosetta, Foldetta) yield inconclusive results. High‑accuracy assessments show AlphaMissense‑Optimized as pathogenic, the SGM Consensus also as pathogenic, while Foldetta remains uncertain. Overall, the majority of evidence points toward a pathogenic impact, which does not contradict the ClinVar “Uncertain” status but suggests the variant is more likely pathogenic rather than benign.

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.

All other evaluated tools—SGM‑Consensus, REVEL, FoldX, Rosetta, Foldetta, premPS, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, AlphaMissense‑Default, and AlphaMissense‑Optimized—predict it to be pathogenic. High‑accuracy assessments further support a deleterious effect: AlphaMissense‑Optimized predicts Pathogenic; the SGM Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) indicates Likely Pathogenic; and Foldetta (combining FoldX‑MD and Rosetta outputs) predicts Pathogenic.

While the backbone amide group of Leu431 forms an H-bond with the carbonyl group of His427, the cyclic five-membered pyrrolidine ring of Pro431, lacking the necessary amide group, cannot do the same. Thus, although the cyclic five-membered pyrrolidine ring of Pro431 packs almost as favorably as the side chain of Leu431 in the hydrophobic niche, the residue swap causes the α helix to partially unfold in the variant simulations.

In the variant simulations, the sec-butyl group of Ile434 is able to form the same hydrophobic interactions. Accordingly, the residue swap does not negatively affect the protein structure based on the simulations.

In the variant simulations, the indole ring of Trp435 fits into the same niche despite its considerably bulkier size. Additionally, the side chain forms an H-bond with the backbone carbonyl of Leu696 in an α helix (res. Asp684-Gln702). Although no apparent negative changes are observed during the variant simulation, the size difference between the swapped residues could affect the protein folding process.

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.

The iso-propyl side chain of Val464 is similarly hydrophobic but considerably smaller than the original phenyl ring of Phe464. To compensate for the size difference, neighboring residues need to fill in the gap in the variant simulations.The phenolic side chain of Tyr428, located at the middle bend of an α helix (res. Glu436-Pro413), assumes a new position in the inter-helix space or rotates inward next to the third α helix (res. Asn440-Lys460) when the stable H-bond between Tyr428 and Asp467 seen in the WT simulations breaks. The residue swap also leads to the loss of the methionine-aromatic interaction between the Met468 and Phe464 side chains, which could weaken the integrity of the parent α helix (res. Ala461-Phe476). Although the simulations likely underestimate the full adverse effect of the introduced mutation during folding, the two opposing α helices (res. Ala461–Phe476 and res. Glu436-Pro413) move substantially closer to each other in the variant simulations.

Prediction tools cluster into two groups: benign predictions come from REVEL and SIFT, while the remaining tools—FoldX, Rosetta, premPS, PROVEAN, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, ESM1b, FATHMM, and AlphaMissense‑Default—indicate pathogenicity. High‑accuracy assessments further support a deleterious effect: AlphaMissense‑Optimized is uncertain; the SGM Consensus, derived from a majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN, reports likely pathogenic; and Foldetta, which combines FoldX‑MD and Rosetta stability outputs, predicts pathogenic.

In the variant simulations, the iso-propyl side chain of Val465 is equally sized and similarly hydrophobic as the original side chain of Leu465. Hence, the mutation does not exert any negative effects on the protein structure based on the variant simulations.

In the variant simulations, the cyclic five-membered pyrrolidine ring of Pro465 is not as optimal as the side chain of Leu465 for filling the three α helix hydrophobic niche. Although the residue swap does not cause a large-scale conformational shift during the simulations, the H-bond between the backbone amide group of Leu465 and the backbone carbonyl group of Ala461 is lost. This, in turn, breaks the continuity of the α helix secondary structure element.

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.

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.

Glu496 also forms a hydrogen bond with Ser449 on an opposing helix (res. Val441-Ser457). In the variant simulations, Gly496 cannot form these salt bridges, which could weaken the secondary structure. Additionally, the loss of the hydrogen bond with Ser449 on the opposite helix can weaken the tertiary structure assembly. Moreover, glycine is an α-helix breaker, and it is seen to weaken the integrity of the helix as the hydrogen bonding between the backbone atoms of Gly496 and Ala493 breaks down. Also, due to its location at the GAP-Ras interface, the interaction of Glu496 with Arg499 and Lys492 might play a role in complex association and stability, which cannot be fully addressed using the SynGAP solvent-only simulations.

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.

High‑accuracy assessments show AlphaMissense‑Optimized as benign, the SGM Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN) as likely benign, and Foldetta (combining FoldX‑MD and Rosetta outputs) as pathogenic. Overall, the majority of predictions lean toward a benign effect, and this does not contradict the ClinVar uncertain status.

Leu489-Glu519). The sec-butyl side chain of Ile501 is hydrophobically packed with other residues in the inter-helix space (e.g., Leu500, Tyr497, Phe679) in the WT simulations. In the variant simulations, the hydroxyl group of Thr501 forms a hydrogen bond with the backbone atoms of Tyr497 on the same α-helix, which may weaken the α-helix integrity. Additionally, the polar hydroxyl group of Thr501 is not suitable for the hydrophobic inter-helix space, and thus, the residue swap could affect protein folding. However, Ile501 is followed by Gly502, which facilitates a hinge in the middle of the α-helix, making further weakening caused by Thr501 unlikely to be harmful to the α-helix integrity.

No tool in the dataset predicts a benign effect. High‑accuracy assessments reinforce this consensus: AlphaMissense‑Optimized is pathogenic; the SGM Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) is “Likely Pathogenic”; and Foldetta, which integrates FoldX‑MD and Rosetta stability calculations, is pathogenic. Based on the uniform predictions, the variant is most likely pathogenic, a conclusion that contradicts the current ClinVar “Uncertain” classification.

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.

In the variant simulations, the hydroxyl group of Ser510 forms a hydrogen bond with the backbone atoms of Leu506 and Gly511 in the same α-helix, which could further weaken the α-helix integrity. This α-helix already shows weakness in the WT simulations due to Gly511.

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.

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.

Additionally, the thiol side chain of Cys547 weakly hydrogen bonds with the carbonyl group of Leu543 in the same α-helix. In the variant simulations, the bulkier, positively charged guanidinium group of Arg547 must rotate out of the hydrophobic space. Consequently, it forms ionic interactions with the carboxylate groups of Glu548 in the same helix and Glu656 in the neighboring α-helix (res. Glu666-Asp644). This causes the two helices to slightly separate, significantly affecting the secondary structure integrity of the latter helix. These negative structural effects could be more pronounced during protein folding and are likely to be undermined in the MD simulations.

High‑accuracy assessments further support this: AlphaMissense‑Optimized is pathogenic; the SGM Consensus (majority vote from AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN) is Likely Pathogenic; and Foldetta, which integrates FoldX‑MD and Rosetta outputs, is pathogenic. Taken together, the overwhelming majority of computational evidence indicates a pathogenic effect, which is in agreement with the ClinVar classification.

Additionally, the thiol side chain of Cys weakly hydrogen bonds with the carbonyl group of Leu543 in the same α-helix. In the variant simulations, the bulkier phenol ring of Tyr547, with its polar hydroxyl group, is less suited for the hydrophobic space. Consequently, it moves outside and forms a hydrogen bond with the carbonyl group of Phe652 in the neighboring α-helix (res. Glu666-Asp644). This causes the two helices to slightly separate, negatively affecting the secondary structure integrity of the latter helix.

Prediction tools that classify the variant as benign include FoldX, Rosetta, Foldetta, PROVEAN, SIFT, and AlphaMissense‑Optimized, while those that predict pathogenicity are REVEL, polyPhen‑2 (HumDiv and HumVar), ESM1b, and FATHMM. Two tools report an uncertain outcome: premPS and AlphaMissense‑Default. High‑accuracy assessments show AlphaMissense‑Optimized as benign, Foldetta as benign, and the SGM Consensus (majority vote from AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) as pathogenic. Overall, the majority of predictions lean toward a benign effect, and this does not contradict the ClinVar “Uncertain” classification. Thus, the variant is most likely benign based on the current computational evidence. Disclaimer: This summary was generated using AI and should be interpreted alongside expert review.

In the variant simulations, the pyrrolidine side chain of Pro551 is not as optimal as leucine for hydrophobic packing with the nearby residues. Moreover, Pro551 lacks the amide group, and thus, it cannot form a hydrogen bond with the backbone carbonyl group of Cys547, which disrupts the continuity of the secondary structure element.

Uncertain results are reported by FoldX, Foldetta, and premPS. High‑accuracy assessments show AlphaMissense‑Optimized as pathogenic, the SGM‑Consensus as Likely Pathogenic, and Foldetta as inconclusive. Overall, the consensus of the available predictions indicates that K553T is most likely pathogenic, which does not contradict the current ClinVar status of uncertain significance.

In the WT simulations, Lys533 packs against Phe513, and its amino side chain occasionally forms an ionic interaction with the carboxylate group of Glu512 from an opposing α-helix (res. Gln503-Tyr518). In the variant simulations, Thr533 is unable to reproduce these interactions, potentially weakening the integrity of the tertiary structure. Additionally, Thr533 forms a hydrogen bond with the backbone carbonyl group of Leu549 in the same helix, which could potentially weaken the secondary structure.

It also forms a hydrogen bond with the backbone carbonyl group of Cys552, which weakens the α-helix integrity. In the variant simulations, the hydroxyl group of Ser556 forms a more stable hydrogen bond with the backbone carbonyl oxygen of the same helix residue, Cys552, compared to Asn556 in the WT. Serine has a slightly lower propensity to reside in an α-helix than asparagine, which may exacerbate the negative effect on the α-helix integrity.

In the variant simulations, Arg572 forms hydrogen bonds with other residues in the inter-helix space, such as Ser592 and the backbone carbonyl atom of Leu465. Additionally, Arg572 hydrophobically packs its carbon chain with surrounding residues such as Phe569 and Ile589.However, the introduced residue arginine is too hydrophilic and charged for the hydrophobic space, disrupting the hydrophobic packing of the inter-helix space. Indeed, in the second simulation, Arg572 successfully escapes the hydrophobic niche completely, causing the whole protein to partially unfold.Overall, the residue swap is highly likely to cause critical protein folding problems, as evidenced by the effects seen in the variant simulations.

In the variant simulations, all these favorable packing interactions are completely removed, as the introduced residue Gly572 essentially lacks a side chain altogether. Although not observed in the simulations, the residue swap could also weaken the integrity of the helix (res.

In the variant simulations, all these favorable packing interactions are completely removed, as the introduced residue Ser572 is too hydrophilic or small to fill the hydrophobic niche occupied by the indole ring. Moreover, the hydroxyl group of Ser572 forms hydrogen bonds with the carbonyl groups of Glu567 and Val568 within the same α-helix, potentially lowering its integrity. Overall, the residue swap is highly likely to cause critical protein folding problems that are underestimated based on the effects seen in the variant simulations.
c.1718G>A	R573Q 2D 3DClick to see structure in 3D Viewer AISynGAP1 missense variant R573Q is reported in ClinVar as Pathogenic (ClinVar ID 1176819.0) and is not present in gnomAD. Functional prediction tools largely agree on a deleterious effect: pathogenic predictions come from SGM‑Consensus, REVEL, FoldX, Foldetta, premPS, PROVEAN, polyPhen‑2 (HumDiv and HumVar), ESM1b, FATHMM, and AlphaMissense‑Default, while only SIFT predicts a benign outcome. Two tools give inconclusive results: Rosetta (Uncertain) and AlphaMissense‑Optimized (Uncertain). High‑accuracy assessments further support pathogenicity: AlphaMissense‑Optimized remains uncertain, the SGM Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) is Pathogenic, and Foldetta (combining FoldX‑MD and Rosetta outputs) is Pathogenic. Overall, the preponderance of evidence indicates the variant is most likely pathogenic, consistent with its ClinVar classification.

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, although the carboxamide group of the Gln573 side chain can hydrogen bond with the carboxylate group of Glu582 or the hydroxyl group of Ser668, these interactions are not as coordinated, stable, or strong as those of the positively charged Arg573. 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.

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.

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 on a slightly α-helical loop (res. Glu478-Thr488) preceding another α helix (res. Ala461-Phe476).In the variant simulations, the neutral carboxamide group of the Gln581 side chain cannot form any of these salt bridges. Instead, it packs hydrophobically against Met477 and Ile587 or forms hydrogen bonds sporadically with nearby residues (e.g., Asp583, Arg587). Thus, although no drastic changes are observed in the variant simulations, the residue swap could weaken the tertiary structure assembly.

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.

The protonated epsilon nitrogen forms a hydrogen bond with the backbone carbonyl group of Ala469, which can disrupt the continuity of the opposing α helix (res.

The sec-butyl hydrocarbon side chain of Ile589 packs favourably with multiple residues in the inter-helix hydrophobic space (e.g., Phe569, Ile667, and Leu664).Although the S-methyl thioether group of the Met589 side chain in the variant is longer than the branched side chain of isoleucine, it stacks favourably with the aromatic phenol ring. Additionally, the polar sulphur atom forms a weak hydrogen bond with the guanidinium group of Arg573, which in turn forms a salt bridge with the carboxylate group of Asp586.Overall, the hydrophobic packing in the inter-helix space does not appear to be disrupted in the variant simulations.

However, the polar nitrogen atoms introduce hydrogen bond donors and acceptors into the previously hydrophobic space. The epsilon protonated nitrogen of His593 forms a stable hydrogen bond with the phenol group of the Tyr505 side chain in an α helix (res. Gln503-Tyr518).While the residue swap could affect the tertiary assembly and the underlying protein folding process, it is difficult to determine if the mutation would be tolerated based solely on the variant simulations.

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.

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.

Instead, it interacts with the hydrophobic isopropyl side chain of Val555 from the opposing α-helix (res. Ala533-Val560). This residue swap may therefore cause issues during protein folding.

Ser641-Glu666), such as Ile589, Phe663, and Met660. In the variant simulations, the hydroxyl group of Ser664 forms hydrogen bonds with the backbone carbonyl oxygen of another helix residue, such as Met660 or Gln661. This interaction is known to destabilize hydrogen bonding in the α-helix, but this effect was not observed in the simulations. Additionally, Ser664 occasionally forms hydrogen bonds with the carboxylate group of Asp586 on another α-helix (res. Glu582-Met603), which could minimally influence the tertiary structure assembly. Despite these interactions, no major negative effects on the protein structure were observed during the simulations.

In the variant simulations, the carbonyl group of Gly666 occasionally forms hydrogen bonds with Lys566 and Asn669. However, Gly666 lacks a side chain and thus cannot maintain as well-coordinated a hydrogen-bond network as Glu666 in the WT, which may affect the tertiary structure assembly.

The SGM Consensus, derived from a majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN, is classified as likely pathogenic. High‑accuracy assessments give AlphaMissense‑Optimized a benign prediction, while the SGM Consensus remains pathogenic; Foldetta, which integrates FoldX‑MD and Rosetta stability outputs, is inconclusive. Overall, the balance of evidence slightly favors a pathogenic interpretation, but the predictions are not unequivocal.

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.

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.

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.

Only polyPhen‑2 HumDiv classifies the change as pathogenic. High‑accuracy assessments further support a benign outcome: AlphaMissense‑Optimized is benign, the SGM‑Consensus (majority vote) is benign, and Foldetta, which integrates FoldX‑MD and Rosetta stability predictions, is inconclusive and therefore not considered evidence.

Functional prediction tools cluster into two groups: benign predictions come from REVEL, Rosetta, Foldetta, FATHMM, and AlphaMissense‑Optimized, while pathogenic predictions arise from premPS, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, AlphaMissense‑Default, and the SGM‑Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN). High‑accuracy assessments show AlphaMissense‑Optimized labeling the variant as benign, SGM‑Consensus indicating pathogenicity, and Foldetta (integrating FoldX‑MD and Rosetta outputs) classifying it as benign. With three high‑accuracy tools giving benign or uncertain results and only one (SGM‑Consensus) suggesting pathogenicity, the overall evidence leans toward a benign effect. This prediction aligns with the ClinVar benign classification, indicating no contradiction. Disclaimer: This summary was generated using AI and should be interpreted alongside expert review.

In the variant simulations, the pyrrolidine side chain of Pro690 cannot form hydrogen bonds with the C2 domain residue, resulting in the loss of this inter-domain connection. Additionally, prolines lack a free amide group necessary for hydrogen bonding with the carbonyl group of Gly686, introducing a slight bend in the α-helix and compromising its integrity.

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.

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.
