| c.3806T>A | V1269E 2D  AIThe SynGAP1 missense change V1269E is listed in ClinVar with an “Uncertain” status and is not reported in gnomAD. Prediction tools that flag the variant as benign include only REVEL, whereas the remaining predictors—PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, FATHMM, AlphaMissense‑Default, and AlphaMissense‑Optimized—consistently classify it as pathogenic. The SGM‑Consensus, derived from a majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN, also reports a “Likely Pathogenic” outcome. High‑accuracy assessments show AlphaMissense‑Optimized as pathogenic and the SGM‑Consensus as likely pathogenic; the Foldetta stability analysis is unavailable. Overall, the preponderance of evidence points to a pathogenic effect, which does not contradict the ClinVar designation of uncertainty.

| c.3923G>A | R1308H 2D AIThe SynGAP1 missense variant R1308H (ClinVar ID 1996244.0) is listed as Uncertain in ClinVar and is present in gnomAD (ID 6‑33451797‑G‑A). Prediction tools that agree on a benign effect include REVEL, ESM1b, AlphaMissense‑Default, and AlphaMissense‑Optimized. Tools that agree on a pathogenic effect are PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, and FATHMM. High‑accuracy assessment shows AlphaMissense‑Optimized predicts a benign outcome; the SGM Consensus, derived from a majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN, is inconclusive, and Foldetta results are unavailable. Consequently, the overall computational evidence leans toward a pathogenic interpretation, but the presence of a single high‑accuracy benign prediction and the inconclusive SGM Consensus leave the variant’s effect uncertain. This computational assessment does not contradict the ClinVar status, which remains Uncertain.

Functional prediction tools show a split: benign calls come from REVEL, ESM1b, FATHMM, and AlphaMissense‑Optimized, while pathogenic calls come from PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, and AlphaMissense‑Default. High‑accuracy assessments give a benign result from AlphaMissense‑Optimized, an inconclusive SGM Consensus (a 2‑vs‑2 majority vote among AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN), and no available Foldetta stability data. Overall, the majority of predictions (5/10) indicate pathogenicity, and the high‑accuracy tools do not overturn this trend. Therefore, the variant is most likely pathogenic, which does not contradict its ClinVar status of Uncertain.

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 assess the variant’s effect fall into two groups: the single benign prediction comes from REVEL, while all other evaluated algorithms (FoldX, Rosetta, Foldetta, premPS, PROVEAN, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, SIFT, ESM1b, FATHMM, AlphaMissense‑Default, AlphaMissense‑Optimized) predict a pathogenic outcome. High‑accuracy methods reinforce this view: AlphaMissense‑Optimized reports pathogenic, the SGM Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) is “Likely Pathogenic,” and Foldetta (combining FoldX‑MD and Rosetta outputs) also predicts pathogenic.

In the WT simulations, Ser204 simultaneously forms hydrogen bonds with the backbone carbonyl of Asp201 and the hydroxyl group of Thr224, helping to stabilize the two anti-parallel β strands (res. Ile205-Lys207 and Cys219-Thr223) at the end of the β sheet. Since the thiol group of cysteine forms weaker hydrogen bonds than the hydroxyl group of serine, Cys204 does not maintain the hydrogen bond network as stably as Ser204 in the variant simulations.

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.

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. Moreover, proline lacks a free amide group necessary for hydrogen bonding with the carbonyl group of Arg687, introducing a slight bend in the α-helix and compromising its integrity. | ||||||||||

Prediction tools that report benign include polyPhen‑2 HumVar, FATHMM, AlphaMissense‑Default, and AlphaMissense‑Optimized. Tools that predict pathogenicity are REVEL, PROVEAN, polyPhen‑2 HumDiv, SIFT, and ESM1b. Four tools give uncertain or inconclusive results: FoldX, Rosetta, Foldetta, and premPS. The SGM Consensus, derived from a majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN, is inconclusive because the votes are evenly split.

Arg259-Arg272), forms salt bridges with the carboxylate groups of Asp684 at the end of an α helix (res. Ile683-Gln702, GAP domain) and Asp261 on the same β strand. 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. | |||||||||

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. | |||||||||

Arg259-Arg272), packs against multiple hydrophobic residues such as Leu266, Phe314, Leu317, and Leu323 in the WT simulations. In the variant simulations, the hydrophilic carboxamide group of the Gln264 side chain is not suitable for the hydrophobic niche, causing the hydrophobic residues to make room for the swapped residue. Additionally, the carboxamide group of Gln264 forms hydrogen bonds with the backbone amide groups of Arg405 and Lys256 in the β sheet and the carbonyl group of Val350 in an α helical section of a nearby loop (res. Pro359-Phe358). The residue swap disrupts the packing of the C2 domain, which could adversely affect the C2 domain structure during folding. This disruption could potentially weaken the stability of the SynGAP-membrane association. | |||||||||

Prediction tools that agree on a benign effect include REVEL, FoldX, Rosetta, Foldetta, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, AlphaMissense‑Default, and AlphaMissense‑Optimized. Only FATHMM predicts a pathogenic outcome, while premPS is uncertain. The SGM‑Consensus, derived from a majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN, is Likely Benign. High‑accuracy assessments are consistent: AlphaMissense‑Optimized predicts benign, the SGM‑Consensus (majority vote) is benign, and Foldetta (combining FoldX‑MD and Rosetta outputs) also predicts benign. No prediction contradicts the ClinVar benign status; overall, the evidence strongly supports that E273D is most likely benign.

Because the C2 domain loop faces the membrane surface, the potentially crucial role of the carboxylate group of Glu273 or Asp273 on SynGAP-membrane association cannot be fully explored via solvent-only simulations.As a minor note, the neighboring residue Arg272, which stacks with the indole ring of the Trp362 side chain and directly faces RasGTPase, forms a salt bridge more often with Asp273 than with the non-mutated Glu273 in the simulations. Regardless, due to the similar physicochemical properties of the WT and variant residues at the membrane interface, the residue swap is likely to be well tolerated. | ||||||||

Prediction tools that indicate a benign effect include only REVEL, whereas the remaining pathogenic‑predicating tools—FoldX, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, FATHMM, AlphaMissense‑Default, and the SGM‑Consensus—consistently predict a deleterious impact. Uncertain or inconclusive results come from Rosetta, Foldetta, premPS, and AlphaMissense‑Optimized. High‑accuracy assessments show AlphaMissense‑Optimized as uncertain, the SGM‑Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) as pathogenic, and Foldetta as uncertain. Overall, the preponderance of evidence points to a pathogenic effect for R279W, which contrasts with the ClinVar designation of uncertain significance.

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

Arg279-Leu286), packs against multiple hydrophobic residues (e.g., Ile268, Leu284, Trp308, Leu327). In the variant simulations, the hydroxyl-containing side chain of Ser282 is more hydrophilic and, hence, not as favorable as Cys282 for this hydrophobic niche. Due to this polarity difference, the residue swap could potentially weaken the hydrophobic packing of the C2 domain during the folding process.Moreover, because the C2 domain interacts with the membrane, there could also be a negative effect on the stability of the SynGAP-membrane association. However, no large-scale structural changes were observed during the variant simulations. The hydroxyl group of Ser282 forms a hydrogen bond with the backbone carbonyl group of His326 in another β strand (res. Ala322-Arg329), which competes directly with the backbone amide group of Glu283 within the secondary structure element. | |||||||||||

All other evaluated algorithms predict a pathogenic outcome: FoldX, Foldetta, premPS, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, FATHMM, AlphaMissense‑Default, AlphaMissense‑Optimized, and the SGM‑Consensus (majority vote from AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN). Rosetta’s output is uncertain and is therefore not counted as evidence. High‑accuracy assessments further support pathogenicity: AlphaMissense‑Optimized predicts pathogenic, the SGM‑Consensus indicates Likely Pathogenic, and Foldetta (combining FoldX‑MD and Rosetta) also predicts pathogenic.

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. | |||||||||

Pro364- Pro398) between two anti-parallel β sheet strands (res. Thr359-Pro364, res. Ala399-Ile411). Because, the Ω loop is assumed to be directly interacting with the membrane, it is only seen to move arbitrarily throughout the WT solvent simulations. The Ω loop is potentially playing a crucial loop in the SynGAP-membrane complex association, stability and dynamics, regardless, this aspect cannot be addressed through the solvent simulations only. The Ω-loops are known to have a major role in protein functions that requires flexibility and thus, they are rich in glycines, prolines and to a lesser extent, hydrophilic residues to ensure maximum flexibility. Thus, Ser370 in the variant is potentially tolerated in the Ω loop. However, since the effect on the Gly-rich Ω loop dynamics can only be well-studied through the SynGAP-membrane complex, no definite conclusions can be withdrawn. | |||||||||

Functional prediction tools that classify the variant as benign include REVEL, FoldX, Rosetta, Foldetta, premPS, and AlphaMissense‑Optimized. Those that predict pathogenicity are PROVEAN, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, SIFT, ESM1b, and FATHMM. The remaining tool, AlphaMissense‑Default, gives an uncertain result. High‑accuracy assessments show AlphaMissense‑Optimized as benign, the SGM Consensus (majority vote from AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN) as pathogenic, and Foldetta (combining FoldX‑MD and Rosetta outputs) as benign. Overall, the majority of predictions lean toward pathogenicity, while two high‑accuracy methods support a benign effect. Thus, the variant is most likely pathogenic based on the current computational evidence, which does not contradict its ClinVar status of uncertain significance.

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.

However, in the variant simulations, the negatively charged carboxylate group of the Asp306 side chain is not suitable for this hydrophobic niche. Consequently, the side chain moves out to interact with Ser300 in the β strand (res. Met289-Arg299) and the guanidinium group of Arg299 in the β hairpin loop.In the third simulation, the residue swap disrupts the C2 domain secondary structure and tertiary assembly to a large degree when the amino group of the Lys297 side chain rotates to form a salt bridge with Asp306. This drastic effect could potentially reflect the challenge presented by the residue swap during the C2 domain folding. Because the residue swap affects the C2 domain structure, the SynGAP-membrane association could also be impacted.

Functional prediction tools cluster into two groups: benign predictions come from REVEL, PROVEAN, SIFT, and FATHMM, while pathogenic predictions arise from polyPhen‑2 HumDiv, polyPhen‑2 HumVar, ESM1b, AlphaMissense‑Default, and AlphaMissense‑Optimized. Tools that returned uncertain results—FoldX, Rosetta, Foldetta, and premPS—do not contribute to the assessment. High‑accuracy methods give the following: AlphaMissense‑Optimized predicts pathogenic; the SGM Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) is inconclusive, with two pathogenic and two benign calls; Foldetta also reports an uncertain stability change. Overall, the balance of evidence favors a pathogenic effect for F476L, which contrasts with the ClinVar designation of uncertain significance.

In contrast, in the variant simulations, the positively charged guanidinium group of the Arg323 side chain is unsuitable for the hydrophobic niche. Consequently, the side chain either rotates away from the center of the C2 domain or, if it remains within the C2 domain core, it reorients nearby residues to form hydrogen bonds. Regardless, the residue swap extensively disrupts the C2 domain structure. | |||||||||

Met289-Pro298), packs against the phenol ring of the Tyr281 side chain or forms a salt bridge with the carboxylate group of Glu283 on the outer side of the C2 domain. 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. | |||||||||

Instead, the hydroxyl group of the Ser342 side chain forms a hydrogen bond with the imidazole ring of His326 in a neighboring β strand (res. Ala322-Asp330). This disrupts the formation of a hydrogen bond between His326 and the carboxylate group of the Glu283 side chain from another β strand (res. Arg279-Cys285). 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, as the hydroxyl group of Ser342 could form hydrogen bonds with membrane-facing loop residues. However, this phenomenon cannot be addressed using solvent-only simulations. | ||||||||||||
| c.1025A>G | Y342C 2D 3DClick to see structure in 3D Viewer AISynGAP1 missense variant Y342C is listed in ClinVar as Benign (ClinVar ID 1213078.0) and is observed in gnomAD (ID 6‑33437930‑A‑G). 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. Overall, the majority of predictions support a pathogenic effect, contradicting the ClinVar benign classification.

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. | |||||||||

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

In the variant simulations, the sec-butyl side chain of Ile343 is basically able to form the same interactions as valine due to its similar hydrophobic profile. The residue swap also does not seem to cause negative effects on the protein structure based on the simulations. | ||||||||
| c.1030G>A | G344S 2D 3DClick to see structure in 3D Viewer AIThe SynGAP1 missense variant G344S is listed in ClinVar (ID 981240.0) as Pathogenic and is not reported in gnomAD. Prediction tools that assess pathogenicity all agree: REVEL, FoldX, Rosetta, Foldetta, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, FATHMM, AlphaMissense‑Default, and AlphaMissense‑Optimized all classify the variant as pathogenic; the only inconclusive result is premPS, which is marked Uncertain. No tool predicts a benign effect. High‑accuracy assessments reinforce this: 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 pathogenic. Thus, the variant is most likely pathogenic, and this prediction aligns with its ClinVar status.

Gly341-Pro349) to have a slight twist. Within a β strand, side chains normally alternate between outward and inward positions, but glycine is an exception as it allows the alternating pattern to skip a residue. Introducing serine or any other residue with a side chain at position 344 prevents this unique skip in the alternating pattern, causing structural strain or likely preventing correct folding altogether. Additionally, Tyr342 shields Gly344 from the solvent, contributing to twist formation in the β sheet and stabilizing the β-strand.In the variant simulations, the side chain of Ser344 assumes the inward position. However, the hydrophobic niche formed by multiple C2 domain residues (e.g., Val365, Val343, Leu327) is not accommodating for its hydroxyl group. The outward position, not seen in the simulations, would be equally disadvantageous due to the presence of hydrophobic residues on that side as well (e.g., Leu345, Tyr342). Serine is also not well-suited for twist formation, as it tends to suppress twisting and bending in β sheets. At this position, the hydroxyl group of Ser344 could also form hydrogen bonds with the backbone atoms of the Gly-rich Ω loop in the C2 domain (e.g., Thr366, Leu367, Gly378; res. Pro364-Pro398), potentially adversely affecting membrane-loop dynamics and ultimately compromising the stability of the SynGAP-membrane association. | ||||||||||

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

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

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. | ||||||||

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.
