Functional prediction tools cluster into two groups: benign predictions (REVEL, Rosetta, premPS, FATHMM) and pathogenic predictions (PROVEAN, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, SIFT, ESM1b, AlphaMissense‑Default). Uncertain results come from FoldX, Foldetta, and AlphaMissense‑Optimized. High‑accuracy assessments further support pathogenicity: AlphaMissense‑Optimized is inconclusive, but the SGM Consensus—derived from a majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN—classifies the variant as Likely Pathogenic, and Foldetta also yields an uncertain stability change.

Functional prediction tools cluster into two groups: benign calls are made by REVEL, PROVEAN, SIFT, FATHMM, and AlphaMissense‑Optimized, whereas pathogenic calls come from polyPhen‑2 (HumDiv and HumVar) and ESM1b; AlphaMissense‑Default remains uncertain. High‑accuracy assessments further support a benign outcome: AlphaMissense‑Optimized predicts benign, and the SGM Consensus—derived from a majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN—also yields a benign verdict. Foldetta, a protein‑folding stability method that integrates FoldX‑MD and Rosetta outputs, did not provide a result for this variant.

Uncertain predictions from FoldX, Rosetta, Foldetta, and premPS are treated as unavailable. High‑accuracy assessments show AlphaMissense‑Optimized as benign, 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 R587T, which does not contradict the ClinVar “Uncertain” classification but suggests that the variant is more likely pathogenic rather than benign.

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

Functional prediction tools cluster into two groups: benign predictions come from FoldX, SIFT, and AlphaMissense‑Optimized; pathogenic predictions arise from REVEL, PolyPhen‑2 (HumDiv and HumVar), ESM1b, FATHMM, AlphaMissense‑Default, PROVEAN, and the SGM Consensus score (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN). The high‑accuracy AlphaMissense‑Optimized predicts benign, whereas the SGM Consensus predicts likely pathogenic; Foldetta, a folding‑stability method combining FoldX‑MD and Rosetta outputs, returns an uncertain result and is therefore not factored into the consensus. Overall, the majority of evidence supports a pathogenic effect, which contrasts with the ClinVar uncertain classification. Thus, based on current predictions, the variant is most likely pathogenic, contradicting the ClinVar status.

Prediction tools that classify the variant as benign include SIFT and AlphaMissense‑Optimized, whereas the majority of tools predict pathogenicity: REVEL, PROVEAN, polyPhen‑2 (HumDiv and HumVar), ESM1b, FATHMM, AlphaMissense‑Default, and the SGM‑Consensus (Likely Pathogenic). High‑accuracy assessments show AlphaMissense‑Optimized predicting benign, SGM‑Consensus predicting likely pathogenic, and Foldetta (combining FoldX‑MD and Rosetta outputs) yielding an uncertain result. Overall, the preponderance of evidence points to a pathogenic effect, which is in conflict with the ClinVar benign designation.

Ala533-Val560) next to an α-α loop between two α-helices (res. Gly502-Tyr518 and Ala533-Val560). In the WT simulations, the carboxamide group of the Asn542 side chain forms a hydrogen bond with the backbone carbonyl group of Asn523 and packs favourably against Glu522 from the loop. In contrast, in the variant simulations, the hydroxyl group of the Ser542 side chain is unable to maintain either the hydrogen bond with Asn523 or the packing against the Glu522 side chain. Instead, the hydroxyl group of Ser542 occasionally forms a hydrogen bond with the backbone carbonyl group of Glu538.Altogether, the residue swap results in a looser helix-loop association, which is especially evident in the third replica simulation, where Asn523 moves away from its initial placement next to the α-helix. In short, based on the simulations, the residue swap weakens the GAP domain tertiary structure assembly, which in turn could negatively affect protein folding. | |||||||||||

Functional prediction tools that agree on a benign effect include FoldX, Foldetta, PROVEAN, SIFT, and AlphaMissense‑Optimized. Those that agree on a pathogenic effect are REVEL, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, ESM1b, and FATHMM. Uncertain predictions come from Rosetta, premPS, and AlphaMissense‑Default. High‑accuracy assessments show AlphaMissense‑Optimized as benign, the SGM Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) as pathogenic, and Foldetta as benign. Overall, the majority of high‑confidence tools predict a benign impact, with only one consensus pathogenic prediction. Therefore, the variant is most likely benign based on current computational evidence, and this does not contradict the ClinVar uncertain status.

Ala533-Val560). The iso-propyl group of Val560 favorably packs against Asp508 of the opposing α-helix (res. Gln503-Glu519). However, in the variant simulations, the bulkier thioether side chain of Met560 does not form equally favorable inter-helix interactions. Regardless, no negative structural effects are observed during the simulations. | |||||||||

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. | ||||||||

Prediction tools that classify the variant as benign include REVEL, Rosetta, Foldetta, AlphaMissense‑Default, AlphaMissense‑Optimized, and PROVEAN. Those that predict pathogenicity are premPS, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, SIFT, ESM1b, and FATHMM. The high‑accuracy methods give the following results: AlphaMissense‑Optimized predicts benign; the SGM Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) is inconclusive; and Foldetta predicts benign. With the majority of high‑accuracy tools supporting a benign effect, the variant is most likely benign, which does not contradict its current ClinVar status of uncertain significance.

Arg259-Arg272), is stably maintained in an upright and outward position via stacking with the indole ring of the Trp362 side chain in another β strand (res. Thr359-Pro364). In the WT simulations, Arg272 forms hydrogen bonds with the glycine-rich Ω loop residues (res. Val365-Pro398, e.g., Gly380) and creates a salt bridge with the carboxylate group of the Asp304 side chain.In the variant simulations, the carboxamide group of the Gln272 side chain does not stack with the indole ring of Trp362 as stably as the guanidinium group of Arg272 in the WT. Consequently, the Gln272 side chain is freer to interact with the loop residues than Arg272, potentially negatively affecting the dynamic SynGAP-membrane association. Additionally, Arg272 faces the RasGTPase interface, so the residue swap could impact the SynGAP-Ras complex formation and GTPase activation. | |||||||||

Ser641-Glu666 and res. Leu685-Val699), is involved in a highly coordinated hydrogen-bonding network between residues from two α-helices (res. Ser641-Glu666 and res. Arg563-Glu578) and from the α-α loop itself, such as Lys566, Glu666, and Asn669. Met672 can only form a hydrogen bond with the amino group of the Lys566 side chain via its backbone carbonyl group. Nevertheless, the Lys566-Glu666 salt bridge forms intermittently. This is possible because Asn669 keeps the carboxylate group of Glu666 in the vicinity through hydrogen bonding, and the hydrophobic side chain of Met stays mostly rotated away from the salt bridge. Consequently, no drastic disruption of the hydrogen-bond network that keeps the loop close to the helices occurs in the variant simulations. | ||||||||

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 tryptophan are rarely tolerated. Although no major negative structural effects are observed in the variant simulations, Trp385 may exert drastic effects on the SynGAP-membrane complex dynamics and stability. However, since the effects on Gly-rich Ω loop dynamics can only be studied through the SynGAP-membrane complex, no definite conclusions can be drawn. | 10.1016/j.ajhg.2020.11.011 | |||||||||||

Ser635 forms hydrogen bonds with the backbone atoms of the same helix, which may destabilize the helix, although this is not clearly evident in the simulations. The weakening of the hydrogen bond between Ser635 and Ser590 in the variant may also weaken the tertiary structure assembly between the helices.Additionally, Asn635 is at the GTPase interface.

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 tryptophan are rarely tolerated. Although no major negative structural effects are observed in the variant simulations, Trp379 may exert drastic effects on the SynGAP-membrane complex dynamics and stability. However, since the effect on Gly-rich Ω loop dynamics can only be studied through the SynGAP-membrane complex, no definite conclusions can be drawn | ||||||||||||

Prediction tools that agree on a benign effect include REVEL, FoldX, Foldetta, premPS, SIFT, and FATHMM. Those that predict a pathogenic effect are PROVEAN, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, AlphaMissense‑Default, ESM1b, and the SGM‑Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN). Uncertain predictions from Rosetta and AlphaMissense‑Optimized are treated as unavailable. High‑accuracy results are: AlphaMissense‑Optimized – unavailable; SGM‑Consensus – Pathogenic; Foldetta – Benign. Overall, the predictions are balanced, but the high‑accuracy Foldetta result leans toward benign while the consensus leans toward pathogenic, leaving the assessment inconclusive. Based on the available predictions, the variant is most likely benign, contradicting the ClinVar pathogenic classification.

In the WT simulations, the Met470 side chain also packs against the positively charged guanidinium groups of Arg575, Arg429, and Arg579, which form salt bridges with the negatively charged carboxylate groups of the Asp474 and Asp467 side chains at the protein surface. In the variant simulations, the hydroxyl group of the Thr470 side chain forms an H-bond with the backbone carbonyl group of Ser466 in the α helix, potentially lowering its structural integrity. Importantly, the hydroxyl group of Thr470 also forms an H-bond with the guanidinium group of Arg575, which helps it form a more permanent salt bridge with Asp467. | ||||||||||

The SGM consensus, which aggregates AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN, yields a pathogenic majority. High‑accuracy assessments give AlphaMissense‑Optimized benign, SGM consensus pathogenic, and Foldetta uncertain.

Gly341-Pro349), faces outward in the C2 domain. In the WT simulations, the phenol ring of Tyr342 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 Ser342 side chain cannot participate in the stack formation. 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. | ||||||||||||

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.

These hydrogen-bonding interactions at the β sheet surface contribute to the stability of the secondary structure element and prevent it from unfolding. The new hydrogen bond interactions may be more favorable for structural stability than the steric interactions of the methyl side chain of Ala with the side chains of Gln216 and Cys219 in the WT. However, since the model ends abruptly at the N-terminus, no definite conclusions can be drawn from 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. | |||||||||||

In the WT simulations, the pyrrolidine side chain of Pro715, lacking the backbone amide groups altogether, forces the tight helix turn to take place while also hydrophobically packing with nearby residues (e.g., Leu700, Leu708, Leu714, and Leu718). 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. | |||||||||

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. | |||||||||

Pro364-Pro398) between two anti-parallel β sheet strands (res. Thr359-Pro364 and res. Ala399-Ile411). The Ω loop is assumed to directly interact with the membrane, and it is observed to move arbitrarily throughout the WT solvent simulations. 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. | |||||||||

Cys219-Thr224). Unlike the hydroxyl group of the Thr223 side chain in the WT protein, the methyl side chain of Ala223 cannot form hydrogen bonds with nearby residues Thr228 and Lys207. Without these hydrogen-bonding interactions at the β sheet surface, the secondary structure element becomes unstable and partially unfolds in the variant simulations. However, since the model ends abruptly at the N-terminus, no definite conclusions can be drawn from the simulations. | ||||||||

Functional prediction tools largely agree on a benign effect: REVEL, Rosetta, Foldetta, premPS, PROVEAN, SIFT, ESM1b, AlphaMissense‑Default, and AlphaMissense‑Optimized all predict benign or neutral. In contrast, polyPhen‑2 (HumDiv and HumVar) and FATHMM predict pathogenic. Grouping by consensus, the benign‑predicting tools outnumber the pathogenic ones. High‑accuracy assessments reinforce this view: AlphaMissense‑Optimized is benign; the SGM Consensus, derived from a majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN, is also benign; and Foldetta, which integrates FoldX‑MD and Rosetta stability calculations, reports a benign effect. No evidence from the available tools suggests a deleterious impact.

The backbone carbonyl group of Ser296 also hydrogen bonds with the guanidinium group of Arg279 in another nearby β strand (res. Arg279-Cys285). In the variant simulations, the methyl group of the Ala296 side chain cannot hydrogen bond with Asp330, causing the carboxylate group positioning to fluctuate more than in the WT simulations.Although the residue swap does not seem to affect the anti-parallel β sheet assembly during the simulations, it is possible that the Ser296-Asp330 hydrogen bond plays a crucial role in maintaining the C2 domain fold. Notably, because Ser296 is located near the membrane interface, the potential effect of the residue swap on the SynGAP-membrane association cannot be addressed by solvent-only simulations. | |||||||||||

Pro364-Pro398) between two anti-parallel β sheet strands (res. Thr359-Pro364 and res. Ala399-Ile411). The Ω loop is assumed to directly interact with the membrane, and it is observed to move arbitrarily throughout the WT solvent simulations. This loop potentially plays a crucial role in the SynGAP-membrane complex association, stability, and dynamics. However, this aspect cannot be fully addressed through solvent simulations alone.Ω loops are known to play significant roles in protein functions that require flexibility, and thus hydrophobic residues like valine are rarely tolerated. Although no negative structural effects are visualized in the variant’s simulations, Val391 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. | |||||||||

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.

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

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 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. In short, the residue swap could negatively affect both protein folding and the stability of the SynGAP-membrane association. | |||||||

Prediction tools that agree on a benign effect include REVEL, FoldX, Rosetta, Foldetta, premPS, PROVEAN, ESM1b, FATHMM, AlphaMissense‑Default, and AlphaMissense‑Optimized. Tools that predict a pathogenic effect are polyPhen‑2 HumDiv, polyPhen‑2 HumVar, and SIFT. The SGM‑Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) classifies the variant as “Likely Benign.” High‑accuracy assessments further support a benign outcome: AlphaMissense‑Optimized predicts benign; the SGM‑Consensus itself is benign; and Foldetta (combining FoldX‑MD and Rosetta outputs) predicts benign. Overall, the majority of computational evidence indicates the variant is most likely benign, which does not contradict the current ClinVar “Uncertain” classification.

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 leucine are rarely tolerated. Although no negative structural effects are observed in the variant simulations, Leu385 may exert drastic effects on the SynGAP-membrane complex dynamics and stability.

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

Prediction tools that uniformly indicate a benign effect include REVEL, FoldX, Rosetta, Foldetta, premPS, PROVEAN, SIFT, ESM1b, FATHMM, and AlphaMissense‑Optimized. In contrast, polyPhen‑2 (both HumDiv and HumVar models) predict a pathogenic outcome. High‑accuracy assessments show AlphaMissense‑Optimized as benign; the SGM Consensus—derived from a majority vote of AlphaMissense‑Default (uncertain), ESM1b (benign), FATHMM (benign), and PROVEAN (benign)—also yields a benign classification; Foldetta, which integrates FoldX‑MD and Rosetta stability outputs, predicts benign. Overall, the preponderance of evidence supports a benign impact for K705Q, and this conclusion does not contradict the ClinVar “Uncertain” status.
