c.2075T>C | L692P 2D ![]() 3DClick to see structure in 3D Viewer AIThe SynGAP1 missense variant L692P is listed in ClinVar with an “Uncertain” status (ClinVar ID 847082.0) and is not reported in gnomAD. Prediction tools that agree on a benign effect are limited to FATHMM, while the remaining tools (REVEL, FoldX, Rosetta, Foldetta, premPS, PROVEAN, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, SIFT, ESM1b, AlphaMissense‑Default, AlphaMissense‑Optimized) uniformly predict a pathogenic impact. High‑accuracy assessments further support this: AlphaMissense‑Optimized predicts pathogenic; the SGM Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) indicates “Likely Pathogenic”; and Foldetta, which integrates FoldX‑MD and Rosetta outputs, also predicts pathogenic. Based on the overwhelming consensus of pathogenic predictions, the variant is most likely pathogenic, which does not contradict its current ClinVar “Uncertain” classification.

Leu685-Gln702), engages in hydrophobic packing with nearby residues (e.g., Leu441, Leu431, Leu696) in the inter-helix space. Prolines lack a free amide group necessary for hydrogen bonding with the carbonyl group of Glu688 in the same manner as Leu692 in the WT. Consequently, the residue swap with proline disrupts the continuity of the secondary structure element in the variant simulations. Additionally, the side chain of Pro692 is not as optimal as Leu692 for hydrophobic packing in the inter-helix space. | |||||||||||
c.1873C>G | L625V 2D ![]() AISynGAP1 missense variant L625V is listed in ClinVar with an uncertain significance (ClinVar ID 3392716.0) and is not reported in gnomAD. Functional prediction tools cluster into two groups: benign predictions come from REVEL and FATHMM, while pathogenic predictions are made by premPS, PROVEAN, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, SIFT, ESM1b, and AlphaMissense‑Default. Four tools (FoldX, Rosetta, Foldetta, AlphaMissense‑Optimized) give inconclusive results. High‑accuracy assessments show AlphaMissense‑Optimized as uncertain, SGM Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) as likely pathogenic, and Foldetta as uncertain. Overall, the majority of evidence points toward a pathogenic effect, which does not contradict the ClinVar uncertain status but suggests a higher likelihood of pathogenicity.

c.1259T>C | F420S 2D ![]() 3DClick to see structure in 3D Viewer AIThe SynGAP1 missense variant F420S (ClinVar ID 981441.0) is reported as Pathogenic in ClinVar and is not present in gnomAD. Prediction tools largely agree on a deleterious effect: all listed predictors except FATHMM return a pathogenic or likely pathogenic call. The single benign prediction comes from FATHMM. High‑accuracy assessments reinforce this view: AlphaMissense‑Optimized predicts Pathogenic; the SGM Consensus (majority vote from AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN) yields Likely Pathogenic; and Foldetta, which integrates FoldX‑MD and Rosetta stability outputs, also predicts Pathogenic. No predictions or folding‑stability results are missing or inconclusive. Based on the consensus of these tools, the variant is most likely pathogenic, consistent with its ClinVar status. Disclaimer: This summary was generated using AI and should be interpreted alongside expert review. | Likely Pathogenic | GAP | Likely Pathogenic | 1 | -13.231 | Likely Pathogenic | 1.000 | Likely Pathogenic | Likely Pathogenic | 0.544 | Likely Pathogenic | 5.34 | Destabilizing | 0.1 | 5.73 | Destabilizing | 5.54 | Destabilizing | 2.14 | Destabilizing | -7.43 | Deleterious | 0.998 | Probably Damaging | 0.938 | Probably Damaging | 3.09 | Benign | 0.00 | Affected | 3.37 | 29 | -3 | -2 | -3.6 | -60.10 | 213.3 | 57.8 | 0.0 | 0.0 | -0.4 | 0.1 | X | Potentially Pathogenic | In the WT, the phenyl ring of the Phe420 side chain, located on an α helix (res. 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.1811C>T | S604L 2D ![]() 3DClick to see structure in 3D Viewer AIThe SynGAP1 missense variant S604L is listed in ClinVar with an “Uncertain” status (ClinVar ID 1055027.0) and is present in gnomAD (ID 6‑33440863‑C‑T). Prediction tools that agree on a benign effect are premPS and FATHMM. Tools that predict a pathogenic effect include REVEL, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, AlphaMissense‑Default, and AlphaMissense‑Optimized. FoldX, Rosetta, and Foldetta give uncertain results. High‑accuracy assessments show AlphaMissense‑Optimized as pathogenic, the SGM Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) as Likely Pathogenic, and Foldetta as uncertain. Overall, the majority of evidence points to a pathogenic impact, which does not contradict the ClinVar “Uncertain” classification.

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. | |||||||
c.1304T>G | L435W 2D ![]() 3DClick to see structure in 3D Viewer AISynGAP1 missense variant L435W is listed in ClinVar with an uncertain significance and is not reported in gnomAD. Prediction tools that agree on a benign effect include only FATHMM. The majority of other in silico predictors (REVEL, FoldX, premPS, PROVEAN, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, SIFT, ESM1b, AlphaMissense‑Default, AlphaMissense‑Optimized) classify the change as pathogenic, and the SGM‑Consensus score is “Likely Pathogenic.” High‑accuracy assessments further support a deleterious impact: AlphaMissense‑Optimized predicts pathogenicity, the SGM‑Consensus (majority vote from AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) also indicates likely pathogenic, while Foldetta’s stability analysis is inconclusive. Overall, the computational evidence strongly favors a pathogenic effect, which does not contradict the ClinVar uncertain status.

Met414-Glu436), packs against other hydrophobic residues in an interhelix space (e.g., Val699, Val447, Leu489, Leu439) in the WT 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. | |||||||||||

High‑accuracy assessments further support a deleterious impact: AlphaMissense‑Optimized predicts benign, but the SGM Consensus—derived from a majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN—leans pathogenic, and Foldetta (combining FoldX‑MD and Rosetta outputs) also predicts pathogenic. Overall, the preponderance of evidence points to a pathogenic effect for the variant, which does not contradict the current ClinVar “Uncertain” classification.

Functional prediction tools largely agree on a deleterious effect: benign predictions come from premPS and FATHMM, while the remaining 12 tools (REVEL, FoldX, Rosetta, Foldetta, PROVEAN, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, SIFT, ESM1b, AlphaMissense‑Default, AlphaMissense‑Optimized, and the SGM Consensus) predict pathogenicity. High‑accuracy assessments reinforce this view: AlphaMissense‑Optimized is Pathogenic; the SGM Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) is Pathogenic; and Foldetta, which integrates FoldX‑MD and Rosetta outputs, is also Pathogenic. No predictions are inconclusive. Overall, the computational evidence strongly supports a pathogenic effect, consistent with the ClinVar classification. Therefore, the variant is most likely pathogenic based on the consensus of prediction tools, and this assessment aligns with its ClinVar status.

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

Glu582-Met603), packs against hydrophobic residues (e.g., Ile483, Phe484) of an opposing partially helical loop (res. Phe476-Asn487).In the variant simulations, Pro591 lacks a free backbone amide group and, therefore, cannot form a hydrogen bond with the backbone carbonyl of Arg587 as Ala591 does in the WT. This notably weakens the α helix integrity and compromises the continuity of the helix. In reality, the effect on the structure during protein folding could be more severe. | |||||||||||

Across a panel of in silico predictors, the majority indicate a benign effect: REVEL, PROVEAN, polyPhen‑2 HumVar, SIFT, FATHMM, AlphaMissense‑Default, AlphaMissense‑Optimized, and the SGM‑Consensus (derived from a majority of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN). 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. No other tool provides a pathogenic signal. Consequently, the variant is most likely benign, and this assessment does not contradict the ClinVar uncertain status.

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.

Functional prediction tools largely agree on a benign effect: REVEL, FoldX, Rosetta, Foldetta, PROVEAN, polyPhen‑2 HumVar, SIFT, ESM1b, FATHMM, AlphaMissense‑Optimized, and the SGM‑Consensus all report benign or likely benign. Only polyPhen‑2 HumDiv predicts a pathogenic outcome, while premPS and AlphaMissense‑Default are uncertain. High‑accuracy assessments reinforce the benign consensus: AlphaMissense‑Optimized scores benign, the SGM‑Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) is likely benign, and Foldetta (combining FoldX‑MD and Rosetta outputs) indicates benign stability.

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. | ||||||||

Functional prediction tools largely agree on a benign effect: REVEL, FoldX, Rosetta, Foldetta, premPS, PROVEAN, polyPhen‑2 (HumDiv and HumVar), ESM1b, FATHMM, AlphaMissense‑Default, and AlphaMissense‑Optimized all predict benign. Only SIFT classifies the change as pathogenic. The SGM Consensus, derived from a majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN, reports “Likely Benign.” High‑accuracy assessments reinforce this view: AlphaMissense‑Optimized predicts benign, the SGM Consensus is likely benign, and Foldetta (combining FoldX‑MD and Rosetta outputs) also indicates a benign impact.

In the variant simulations, Tyr481 also alternately stacks with nearby arginine residues, including Arg485, Arg587, and Arg479. The interaction between Tyr481 and Arg479 affects the α-α loop, causing it to fold into a distorted helical structure, an effect that might be more pronounced during protein folding.

The residue swap could affect complex formation with the GTPase and its activation. In the WT simulations, the carboxylate group of Glu486 forms salt bridges with Arg485 and Arg475 on the preceding α-helix (res. Ala461-Phe476). In the variant simulations, Lys486 does not form any specific interactions.

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

Leu715, with a normal amide backbone, could potentially affect protein folding and turn formation, although this was not observed in the variant simulations. Additionally, the hydroxyl group of the Ser715 side chain can form hydrogen bonds with the backbone carbonyl group of Gly712 and disrupt the hydrophobic packing arrangement of the leucine residues from the neighboring α-helices, impacting the GAP domain tertiary assembly. | |||||||||

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.

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. | |||||||

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. | |||||||||

Ala322-Asp330), faces the negatively charged lipid bilayer surface. While the residue swap does not cause any apparent negative effects on the protein structure in the variant simulations, it could adversely affect the SynGAP-membrane association in reality. The positively charged Arg329 side chain forms hydrogen bonds with other loop residues (e.g., Ser371, Asp338) that are expected to dynamically interact with the membrane head group region. However, this phenomenon is beyond the scope of the solvent-only simulations to unravel. Notably, histidine can also be double protonated and positively charged, but this alternative protonation state was not considered in the variant simulations. | |||||||||

c.3184G>A | G1062R 2D ![]() AIThe SynGAP1 missense variant G1062R is listed in ClinVar with an “Uncertain” status and is present in gnomAD (ID 6‑33443736‑G‑A). Prediction tools that agree on a benign effect include REVEL, PROVEAN, ESM1b, FATHMM, polyPhen‑2 HumVar, AlphaMissense‑Optimized, and the SGM‑Consensus score (Likely Benign). Tools that predict a pathogenic effect are polyPhen‑2 HumDiv and SIFT; AlphaMissense‑Default remains uncertain. High‑accuracy assessments show AlphaMissense‑Optimized as benign, the SGM‑Consensus (majority vote from AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) as benign, while Foldetta results are unavailable. Overall, the majority of evidence points to a benign impact, and this conclusion does not contradict the ClinVar “Uncertain” classification.

c.3238G>A | A1080T 2D ![]() AIThe SynGAP1 missense variant A1080T (ClinVar ID 1473274.0) is listed as “Uncertain” in ClinVar and is present in gnomAD (ID 6‑33443790‑G‑A). Prediction tools that agree on a benign effect include REVEL, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, FATHMM, AlphaMissense‑Default, and AlphaMissense‑Optimized. No tool in the dataset predicts a pathogenic outcome. High‑accuracy assessments further support a benign classification: AlphaMissense‑Optimized predicts benign, and the SGM Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN) indicates “Likely Benign.” Foldetta, a protein‑folding stability method combining FoldX‑MD and Rosetta outputs, has no available result for this variant. Overall, the computational evidence strongly suggests the variant is most likely benign, which does not contradict the current ClinVar status of uncertainty.
