Ile205-Pro208), is replaced by the thiol-containing cysteine. 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. However, because the model ends abruptly at the N-terminus, no definite conclusions can be drawn from the simulations.

Thr305-Asn315), packs against multiple hydrophobic residues (e.g., Ile268, Val306, Cys282). The indole group of Trp308 also hydrogen bonds with the backbone atoms of the C2 domain residues forming the anti-parallel β sheet (e.g., Tyr280, Thr294). The introduced Cys308 is smaller than the tryptophan it replaced. The thiol group of the Cys308 side chain is well-suited for the inner hydrophobic part of the C2 domain. Although the negative effects are essentially missing from the simulations, the side chain size difference between the residues is likely to disrupt the hydrophobic packing during folding. At a minimum, the residue swap could affect the C2 domain stability and membrane association.

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, 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.

Arg563-Glu578), forms a salt bridge with the carboxylate groups of Glu582 and/or Asp586 from a nearby α-helix (res. Glu582-Met603) in the WT simulations. 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, the indole ring of the Trp573 side chain is unable to maintain the same level of coordination as the positively charged Arg573 side chain. Indeed, Trp573 is seen hydrogen bonding only briefly with the carboxylate group of Glu582. 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.

AIThe SynGAP1 missense variant R581W is listed in ClinVar with an “Uncertain” status and is not reported in gnomAD. Prediction tools that agree on a benign effect include only Rosetta, whereas the remaining pathogenic‑predicating tools—REVEL, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, FATHMM, AlphaMissense‑Default, and the SGM‑Consensus—consistently classify the variant as deleterious. Uncertain or inconclusive results come from FoldX, Foldetta, premPS, and AlphaMissense‑Optimized. High‑accuracy assessments show AlphaMissense‑Optimized as “Uncertain”; the SGM‑Consensus, derived from a majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN, is “Pathogenic”; and Foldetta remains “Uncertain.” Overall, the preponderance of evidence points to a pathogenic impact, which contrasts with the ClinVar designation of uncertainty.

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 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.

AIThe SynGAP1 missense variant S659F is listed in ClinVar with an uncertain significance and is absent from gnomAD. Functional prediction tools that provide definitive calls cluster into two groups: benign predictions come from REVEL, Rosetta, premPS, polyPhen2_HumVar, FATHMM, and AlphaMissense‑Optimized; pathogenic predictions come from PROVEAN, polyPhen2_HumDiv, SIFT, ESM1b, AlphaMissense‑Default, and the SGM Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN). High‑accuracy assessments show AlphaMissense‑Optimized predicts benign, SGM Consensus predicts pathogenic, and Foldetta (which integrates FoldX‑MD and Rosetta outputs) yields an uncertain result and is therefore unavailable. Overall, the majority of reliable tools favor a pathogenic effect. Thus, the variant is most likely pathogenic, a conclusion that does not contradict the ClinVar uncertain status.

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.

AIThe SynGAP1 missense variant S668F is reported in ClinVar as Pathogenic (ClinVar ID 1309930.0) and is not found in gnomAD. 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.

AISynGAP1 missense variant R259W is listed in ClinVar with an uncertain significance (ClinVar ID 2014570.0) and is not reported in gnomAD. Functional prediction tools that agree on a benign effect are limited to FATHMM, whereas the remaining evaluated algorithms—REVEL, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, AlphaMissense‑Default, AlphaMissense‑Optimized, and the SGM‑Consensus—consistently predict a pathogenic impact. Uncertain results are reported by FoldX, Rosetta, Foldetta, and premPS. High‑accuracy assessments further support pathogenicity: AlphaMissense‑Optimized is pathogenic; the SGM‑Consensus, derived from a majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN, is pathogenic; and Foldetta, which integrates FoldX‑MD and Rosetta stability calculations, remains inconclusive. Overall, the preponderance of evidence indicates that R259W is most likely pathogenic, a conclusion that does not contradict the current ClinVar status of uncertain significance.

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.

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.

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.

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.

R732T
2D
AISynGAP1 missense variant R732T is listed in ClinVar with an uncertain significance and is not reported in gnomAD. Functional prediction tools cluster into two groups: benign (REVEL, PROVEAN, SIFT, FATHMM, AlphaMissense‑Optimized) and pathogenic (polyPhen‑2 HumDiv, polyPhen‑2 HumVar, ESM1b). AlphaMissense‑Default remains uncertain. The high‑accuracy AlphaMissense‑Optimized predicts a benign effect, and the SGM Consensus—derived from a majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN—also favors a benign outcome. Foldetta, a protein‑folding stability method that integrates FoldX‑MD and Rosetta outputs, has no available result for this variant. Overall, the preponderance of evidence from both general and high‑accuracy predictors points to a benign impact, which does not contradict the current ClinVar designation of uncertain significance.

Met289-Pro298), packs against hydrophobic residues of the C2 and PH domains (e.g., Leu317, Leu286, Leu284, Pro208, Val209). 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.

AISynGAP1 G387V is listed in ClinVar with an uncertain significance and is present in gnomAD (variant ID 6-33438065-G-T). Functional prediction tools that report a benign effect include REVEL, premPS, PROVEAN, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, ESM1b, AlphaMissense‑Default, and AlphaMissense‑Optimized. Tools that predict a pathogenic effect are FoldX, Rosetta, SIFT, and FATHMM. The SGM‑Consensus, derived from a majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN, is classified as likely benign, while the Foldetta stability assessment (combining FoldX‑MD and Rosetta) indicates a pathogenic change. High‑accuracy assessments show AlphaMissense‑Optimized as benign, SGM‑Consensus as likely benign, and Foldetta as pathogenic. Overall, the majority of predictions favor a benign impact, and this consensus does not contradict the ClinVar uncertain status; thus the variant is most likely benign.

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.

AIThe SynGAP1 missense variant T723I is listed in ClinVar as Benign (ClinVar ID 436924.0) and is observed in gnomAD (variant ID 6‑33441633‑C‑T). 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. No prediction or stability result is missing or inconclusive. Based on the collective evidence, the variant is most likely benign, and this conclusion is consistent with its ClinVar status.

The Ω loop is assumed to directly interact with the membrane, and it is observed to move arbitrarily throughout the WT solvent simulations. Although the residue swap does not influence the nearby secondary structure elements, proline is often found at the ends of β sheets due to its disfavored status during folding.Additionally, 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 significant roles in protein functions that require flexibility, and thus hydrophobic residues like leucine are rarely tolerated. Although no negative structural effects are visualized in the variant’s simulations, Leu398 may exert drastic effects on the SynGAP-membrane complex dynamics and stability. 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.

In the variant simulations, Leu562 packs more favorably with the nearby hydrophobic residues, and the backbone amide group of Leu562 (absent in proline) does not form any intra-protein hydrogen bonds. However, prolines are well-suited for unstructured regions like loops, and thus, Pro562 in the WT is necessary at the end of the helix to induce a tight turn during folding.

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.

All other evaluated algorithms—REVEL, FoldX, Foldetta, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, FATHMM, AlphaMissense‑Default, AlphaMissense‑Optimized, and the SGM‑Consensus—classify the variant as pathogenic or likely pathogenic, while Rosetta remains inconclusive. High‑accuracy assessments further support a deleterious impact: AlphaMissense‑Optimized predicts pathogenic; the SGM‑Consensus (majority vote from AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) indicates likely pathogenic; and Foldetta, which integrates FoldX‑MD and Rosetta outputs, also predicts pathogenic. **Thus, the variant is most likely pathogenic based on the collective predictions, which does not contradict the ClinVar uncertain status.**

Glu582-Met603), forms a salt bridge with the carboxylate group of Glu495 from another α helix (res. Leu489-Glu519). In the WT simulations, the side chain of Arg596 hydrogen bonds with the backbone carbonyl groups of Asn487, Glu486, Arg485, and Phe484. Additionally, Arg596 can hydrogen bond with the carboxamide group of the Asn487 side chain on an opposing loop that links two α helices (res. Ala461-Arg475, res. Leu489-Glu519).In the variant simulations, the thiol group of the Cys596 side chain is unable to form salt bridges or any of the hydrogen bonds that the Arg596 side chain can. Thus, the residue swap could affect the tertiary structure assembly more profoundly than observed in the simulations. Notably, Arg596 plays a key role in positioning the aforementioned loop, which is crucial for the placement of the “arginine finger” or the Arg485 side chain during RasGTPase activation.

The positively charged guanidinium side chain of arginine is on the outside surface of the hydrophobic C2 domain, resulting in a twist in the β strand. Although this twist is maintained in the variant simulations, replacing the positively charged residue with a more hydrophobic one, such as cysteine, could remove the twist during protein folding.Because Arg293 is positioned at the C2 and PH domain interface, the residue swap could significantly impact the tertiary structure assembly.

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 thiol group of the Cys299 side chain is unable to form any of these well-coordinated or strong interactions, 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. 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.

AIThe SynGAP1 E221V missense variant is reported in ClinVar as Pathogenic (ClinVar ID 2413181.0) and is not found in gnomAD. Functional prediction tools largely agree on a deleterious effect: pathogenic calls come from REVEL, PROVEAN, polyPhen‑2 HumDiv, SIFT, ESM1b, AlphaMissense‑Default, AlphaMissense‑Optimized, and the SGM‑Consensus (majority vote). Benign predictions are limited to premPS, polyPhen‑2 HumVar, and FATHMM. Uncertain results are reported by FoldX, Rosetta, and Foldetta. High‑accuracy assessments reinforce the pathogenic interpretation: AlphaMissense‑Optimized predicts Pathogenic, the SGM‑Consensus also indicates Likely Pathogenic, while Foldetta remains Uncertain. Taken together, the preponderance of evidence supports a pathogenic effect for E221V, and this conclusion aligns with the ClinVar classification, showing no contradiction.

Cys219-Thr224). Unlike the carboxylate group of Glu221, Val221 cannot form hydrogen bonds with Thr223 or a salt bridge with the amino group of the Lys207 side chain. Despite this, the WT simulations containing Glu221 do not show significant differences compared to the variant simulations. However, since the model ends abruptly at the N-terminus, no definite conclusions can be drawn from the simulations.

AIThe SynGAP1 missense variant N556I is catalogued in ClinVar as benign (ClinVar ID 2692844.0) and is observed in gnomAD (ID 6‑33438910‑A‑T). Functional prediction tools cluster into two groups: benign predictions come from Rosetta, Foldetta, and premPS, while pathogenic predictions arise from REVEL, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, FATHMM, AlphaMissense‑Default, and the SGM‑Consensus score. Two tools report uncertainty: FoldX 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 (integrating FoldX‑MD and Rosetta outputs) as benign. Taken together, the majority of predictions favor a pathogenic effect, whereas the ClinVar annotation indicates benign. Thus, the computational evidence contradicts the ClinVar status, suggesting the variant is more likely pathogenic rather than benign.

AIThe SynGAP1 missense variant R573L is listed in ClinVar as Pathogenic (ClinVar ID 521291.0) and is not reported in gnomAD. Functional prediction tools that assess sequence conservation and structural impact uniformly indicate a deleterious effect: REVEL, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, FATHMM, AlphaMissense‑Default, and AlphaMissense‑Optimized all classify the substitution as pathogenic. 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. Based on the collective evidence, the variant is most likely pathogenic, which is consistent with its ClinVar status.

Arg563-Glu578), forms a salt bridge with the carboxylate groups of Glu582 and/or Asp586 from a nearby α-helix (res. Glu582-Met603) in the WT simulations. 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, the aliphatic iso-butyl group of the Leu573 side chain fails to establish any of these interactions, which, in turn, lowers the integrity of the opposing α-helix end (res. Glu582-Met603). Overall, the residue swap has the potential to substantially affect the tertiary structure assembly during the protein folding process.10.1016/j.ajhg.2020.11.011

AIThe SynGAP1 R596L missense variant is listed in ClinVar with an “Uncertain” status and is not reported in gnomAD. Prediction tools that agree on a benign effect are Foldetta and premPS, whereas the remaining pathogenic‑predicting tools—REVEL, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, FATHMM, AlphaMissense‑Default, AlphaMissense‑Optimized, and the SGM‑Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN)—all indicate a deleterious impact. High‑accuracy assessments further support this: AlphaMissense‑Optimized predicts pathogenicity, the SGM‑Consensus (derived from the same four high‑confidence predictors) also indicates likely pathogenic, while Foldetta, which integrates FoldX‑MD and Rosetta stability outputs, predicts a benign effect. Overall, the preponderance of evidence points to a pathogenic effect for R596L, which is consistent with the ClinVar “Uncertain” classification rather than contradicting it.

Glu582-Met603), forms a salt bridge with the carboxylate group of Glu495 from another α helix (res. Leu489-Glu519). In the WT simulations, the side chain of Arg596 hydrogen bonds with the backbone carbonyl groups of Asn487, Glu486, Arg485, and Phe484. Additionally, Arg596 can hydrogen bond with the carboxamide group of the Asn487 side chain on an opposing loop that links two α helices (res. Ala461-Arg475, res. Leu489-Glu519).However, in the variant simulations, the branched hydrocarbon side chain of Leu596 cannot form any of the hydrogen bonds or salt bridges maintained by the considerably bulkier and positively charged Arg596 side chain. Instead, Leu596 packs hydrophobically with the phenyl ring of Phe484 in the linker loop or residues from the opposing helix (e.g., Ile494, Thr491).Thus, the residue swap could affect the tertiary structure assembly more profoundly than observed in the simulations. Notably, Arg596 plays a key role in positioning the aforementioned loop, which is crucial for the placement of the “arginine finger” or the Arg485 side chain during RasGTPase activation.10.1016/j.ajhg.2020.11.011
