The Arg259 side chain also frequently forms hydrogen bonds with the backbone carbonyl groups of Ser257, Asn256, and Asp255. In the variant simulations, the indole ring of the Trp259 side chain cannot form salt bridges or maintain hydrogen bonding with the carboxylate group of Asp684 or other nearby residues. Notably, the amino group of the Lys254 side chain maintains a salt bridge with Asp684 and Glu244 throughout the variant simulations, while it forms a cation-π bond with the indole ring of Trp259 in the variant. This salt bridge is not maintained in the WT simulations. Additionally, the partially or loosely α helical conformation of a lysine-containing loop (res. Lys251-Ser257), which extends to a nearby α helix (res. Met414-Asn426), could be stabilized due to the residue swap. Moreover, the bulky size of the Trp259 side chain requires nearby residues to adjust their positioning to accommodate the introduced residue, weakening the tertiary structure assembly between the C2, PH, and GAP domains. The residue swap potentially causes more severe effects during protein folding or for the SynGAP-membrane interaction than the solvent-only simulations imply. | |||||||||

Lastly, because the Leu274-containing loop faces the membrane surface, the residue swap could also negatively impact the SynGAP-membrane association. | |||||||||

Arg279-Leu286), can form hydrogen bond with the backbone carbonyl groups of nearby loop residues (e.g., Ser296, Ser331, and As332) and form salt bridges with the carboxylate groups of Asp330 and Asp332. In the WT simulations, Arg279 sporadically forms a salt bridge even with the carboxylate group of Glu613, loosely connecting the C2 domain and GAP domain. Meanwhile, the indole ring of the Trp279 side chain is unable to hydrogen bond with the loop residues in the variant simulations. The lack of hydrogen bond or salt bridge formation with the loop residues could be significant, as Arg279 and the loops face the polar head group region of the membrane. Thus, although Trp279 could interact with the membrane surface as a “lipid anchor,” any changes to the wider loop dynamics could still adversely affect the formation of a stable SynGAP-membrane association. However, no definite conclusions on the effect of the residue swap on the SynGAP-membrane association can be drawn from solvent-only simulations. | ||||||||||||

In the variant simulations, the bulky side chain of Arg282 with its positively charged guanidinium group is not suitable for this hydrophobic niche. Consequently, the hydrophobic residues must either make room to accommodate Arg282 or it must escape the hydrophobic C2 domain core.As a result, new hydrogen bonds are formed with the backbone carbonyl groups of the surrounding β sheet residues Ala399, Leu325, and His326, which decreases the unity of the secondary structure elements. Notably, it is likely that the residue swap causes major problems during the C2 domain folding that are not visible in the variant simulations. In fact, even increased lability in the C2 domain could adversely affect the establishment of a stable SynGAP-membrane association. | |||||||||

In the variant simulations, the hydrophilic side chain of Thr468 does not pack favorably in the hydrophobic niche, and the methionine-aromatic stacking is lost. Although the hydroxyl group of Thr468 forms an H-bond with the backbone carbonyl group of Phe464, the integrity of the α helix is not affected in the simulations. No large-scale structural changes are observed during the variant simulations; however, due to the importance of hydrophobic packing, the effects could be more pronounced during protein folding. | ||||||||

Ala461-Phe476), stacks with the phenyl ring of Phe476 and forms a salt bridge with Glu472. Additionally, Arg475 occasionally forms another salt bridge with the carboxylate group of Glu486 on the α-α loop connecting the two α-helices (res. Ala461-Phe476 and Leu489-Glu519) at the GAP-Ras interface. Therefore, Arg475 potentially plays a key role in positioning the loop by interacting with Glu486, which is necessary for the positioning of the “arginine finger” (Arg485) and, ultimately, for RasGTPase activation. In the variant simulations, Asn475 forms a hydrogen bond with Arg479 on the proceeding α-α loop. The absence of Phe476/Arg475 stacking and the Arg475-Glu472 salt bridge weakens the integrity of the terminal end of the α-helix during the variant simulations. 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. | ||||||

Leu489-Glu519) within an inter-helix space of four helices (res. Ala461-Phe476, res. Val441-Ser457, and res. Met414-Glu436), packs with hydrophobic residues (e.g., Cys432, Ala448, Lys444, Ala493, Val447, Met468) in the inter-helix space. In the variant simulations, the phenyl ring of the Phe489 side chain can also pack favorably in the hydrophobic region. However, due to the size difference, the aromatic side chain of Phe489 tends to reposition to escape the tight region to accommodate the larger side chain, stacking with Lys444. Although no apparent negative changes are observed during the variant simulation, the size difference between the swapped residues could affect the protein folding process. | ||||||||

In the WT simulations, the guanidinium group of Arg581 forms salt bridges with the carboxylate groups of Asp583 within the same helix, as well as with Glu478 and/or Glu480 in a slightly α-helical loop (res. Glu478-Thr488) preceding another α helix (res. Ala461-Phe476).In the variant simulations, the neutral indole ring of the Trp581 side chain cannot form any of these salt bridges. Instead, it packs hydrophobically against Met477 and Ile587 without forming any direct hydrogen bonds. The tendency of the loop (res. Asp477-Thr488) to acquire an α-helical structure seems to marginally increase, potentially due to Trp581's inability to coordinate stable hydrogen bonds with the loop residues (e.g., Glu478-Arg581 salt bridge). Additionally, the residue swap could weaken the tertiary structure assembly and negatively affect the overall protein folding process. | ||||||||||
c.1771G>A | A591T 2D ![]() 3DClick to see structure in 3D Viewer AIThe SynGAP1 missense variant A591T is listed in ClinVar with an uncertain significance designation and is observed in gnomAD (variant ID 6‑33440823‑G‑A). Functional prediction tools cluster into two groups: benign predictions come from REVEL, polyPhen‑2 HumVar, FATHMM, and AlphaMissense‑Optimized; pathogenic predictions come from premPS, PROVEAN, polyPhen‑2 HumDiv, SIFT, ESM1b, and AlphaMissense‑Default. The SGM Consensus, derived from a majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN, reports a likely pathogenic outcome. High‑accuracy assessments further show AlphaMissense‑Optimized as benign, SGM Consensus as pathogenic, and Foldetta (combining FoldX‑MD and Rosetta outputs) as uncertain. No other folding‑stability metrics are available. Overall, the balance of evidence favors a pathogenic interpretation, which does not contradict the ClinVar uncertain status.

Glu582-Met603), packs against hydrophobic residues (e.g., Ile483, Phe484) of an opposing partially helical loop (res. Phe476-Asn487).In the variant simulations, the hydroxyl group of Thr591 can form hydrogen bonds with the backbone carbonyl of Ile843 in the opposing loop or the backbone carbonyl group of Arg587. These interactions could either reinforce the tertiary assembly or weaken the α helix unity. Additionally, the Thr591 side chain can hydrogen bond with the guanidinium group of the Arg587 side chain, potentially strengthening the α helix unity.Overall, the residue swap does not seem to cause any major negative effects on the protein structure. | ||||||||
c.1771G>C | A591P 2D ![]() 3DClick to see structure in 3D Viewer AISynGAP1 missense variant A591P is listed in ClinVar with an uncertain significance and is not reported in gnomAD. Functional prediction tools largely converge on a pathogenic effect: pathogenic predictions come from FoldX, Rosetta, Foldetta, premPS, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, AlphaMissense‑Default, and the SGM‑Consensus (Likely Pathogenic). Benign predictions are limited to REVEL and FATHMM. High‑accuracy assessments reinforce the pathogenic view: AlphaMissense‑Optimized predicts pathogenic, the SGM‑Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) is Likely Pathogenic, and Foldetta (combining FoldX‑MD and Rosetta outputs) also indicates pathogenic. Consequently, the variant is most likely pathogenic, a conclusion that contrasts with its ClinVar uncertain status.

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

Prediction tools that agree on a benign effect include only AlphaMissense‑Optimized. All other evaluated algorithms—REVEL, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, FATHMM, AlphaMissense‑Default, and the SGM‑Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN)—predict a pathogenic impact. High‑accuracy assessments further support this: AlphaMissense‑Optimized reports benign, whereas the SGM‑Consensus, derived from the majority of pathogenic predictions, indicates pathogenic. Foldetta, which integrates FoldX‑MD and Rosetta outputs, is inconclusive and therefore not considered evidence. Overall, the preponderance of computational evidence points to a pathogenic effect for L607V, a conclusion that contrasts with the current ClinVar uncertain status.

In the WT simulations, the iso-butyl side chain of Leu607 does not interact with any other residues, but it could potentially interact directly with Ras due to its location at the GAP domain.In the variant simulations, Val607, which has similar size and physicochemical properties to leucine, does not cause any negative effects on the protein structure. However, due to its location at the GAP-Ras interface, the residue swap could affect the complex formation with the GTPase, but this cannot be investigated using solvent-only simulations. | ||||||||

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. | |||||||

High‑accuracy assessments show AlphaMissense‑Optimized classifying the variant as benign, whereas the SGM Consensus (majority vote from AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN) indicates a pathogenic outcome. Foldetta, a protein‑folding stability method combining FoldX‑MD and Rosetta outputs, does not provide a result for this variant. Overall, the majority of computational predictions (five pathogenic versus three benign) lean toward a pathogenic interpretation. Thus, the variant is most likely pathogenic based on current predictions, and this conclusion does not contradict the ClinVar status, which remains uncertain.

The phenol ring of Tyr291 also forms favorable Met-aromatic stacking with the methyl group of Met289. In the variant simulation, the thiol group of the Cys291 side chain is not as suitable for the hydrophobic inter-domain space as the phenol ring of Tyr291. Consequently, the structural unity of the PH domain is weakened and ultimately unfolds in the second simulation. Moreover, the residue swap might result in severe detrimental effects on the C2 domain structure and the C2-PH domain tertiary structure assembly during folding. | ||||||||||

In the WT simulations, the positively charged side chain of arginine remains outside the hydrophobic C2 domain, resulting in a twist in the β strand. The backbone amide bond of Arg293 potentially maintains this twist by forming a hydrogen bond with the carbonyl group of His210 or the hydroxyl group of Ser211 in the anti-parallel β sheet.Although this twist is also maintained in the variant simulations, replacing the positively charged residue with proline, which lacks the backbone amide group altogether, causes the β strand to unfold. Because Arg293 is positioned at the C2 and PH domain interface, the residue swap could significantly impact the tertiary structure assembly. Notably, Arg293 is located at the SynGAP-Ras interface, and its role in complex formation cannot be fully understood through solvent-only simulations. | |||||||||

Thus, in the WT simulations, it contributes to the β hairpin stability. In the variant simulations, the phenol ring of Phe300 cannot form any side chain-related hydrogen bonds, and 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.

Because the carboxylate group can also interact with the GAP domain residues (e.g., Gln612, Tyr614), Glu310 plays a key role in maintaining the tertiary assembly between the C2 and GAP domains.

Ala322-Asp330), forms a hydrogen bond with the carbonyl group of Gly344 on a neighboring β strand (res. Lys336-Pro349) in the WT simulations. In contrast, in the variant simulations, the introduction of Pro327 destabilizes the hydrogen bonding between the two anti-parallel β strands because proline lacks the backbone amide group altogether. Additionally, in the WT simulations, the iso-butyl side chain of Leu327 packs against multiple hydrophobic residues (e.g., Leu274, V400, Val343), whereas the less bulky cyclic five-membered pyrrolidine ring of Pro327 cannot fill the same space as effectively. Thus, although no large-scale unfolding is observed during the variant simulations, the residue swap is likely to cause severe problems for the correct C2 domain folding, which could also affect the SynGAP-membrane association. | 10.1016/j.ajhg.2020.11.011 | ||||||||||

Across general prediction tools, benign calls are made by REVEL and AlphaMissense‑Optimized, whereas pathogenic calls are made by FoldX, Rosetta, Foldetta, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, FATHMM, AlphaMissense‑Default, and the SGM‑Consensus score (Likely Pathogenic). Uncertain results are reported by premPS and ESM1b. High‑accuracy assessments show AlphaMissense‑Optimized predicting Benign, the SGM‑Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) predicting Pathogenic, and Foldetta (combining FoldX‑MD and Rosetta outputs) predicting Pathogenic.

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 positively charged Arg405 side chain also stacks with the aromatic ring of the Phe358 side chain from a loop preceding the β strand (res.

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. | |||||||

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

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

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.

In the variant simulations, the sec-butyl side chain of Ile649 maintains hydrophobic interactions with nearby residues, with no significant effects on the protein structure.However, methionine is known as a bridging motif for aromatic residues, and these Met-aromatic interactions are lost in the variant. Indeed, in the second variant simulation,the bridging of Phe652, Phe648 and Phe639 is completely lost. In reality, the effect could be more severe on the structure during the protein folding. | |||||||||||

The high‑accuracy AlphaMissense‑Optimized tool reports an uncertain outcome, and the SGM Consensus—derived from a majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN—yields a tie (two pathogenic, two benign) and is therefore inconclusive. No Foldetta stability assessment is available for this variant. Overall, the balance of evidence favors a pathogenic interpretation, which does not contradict the current ClinVar designation of Uncertain.

Met289-Pro298, res. Thr305-Asn315), forms hydrogen bonds that stabilize the tight turn. 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. | |||||||||

Thr305-Asn315), is ideally positioned to interact with the hydroxyl and backbone amide groups of Thr295 on a twisted anti-parallel β strand. Because the carboxylate group can also interact with the GAP domain residues (e.g., Gln612, Tyr614), Glu310 potentially plays a key role in maintaining the tertiary assembly between the C2 and GAP domains. In the variant simulations, the carboxylate group of Asp310 can form the same interactions as glutamate; however, due to its one hydrocarbon shorter length, the connections are less stable or less optimal. | |||||||||||

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.

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.

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).

In the variant simulations, the indole ring of the Trp429 side chain cannot form ionic interactions with the acidic residues. Although it forms a H-bond with Ser471, the bonding is not as strong as that of arginine.

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.
