| c.2752G>A | A918T 2D  AISynGAP1 missense variant A918T is listed in ClinVar with an uncertain significance (ClinVar ID 3964538.0) and is present in gnomAD (6‑33443304‑G‑A). Functional prediction tools cluster into two groups: benign predictions come from REVEL, PROVEAN, ESM1b, FATHMM, AlphaMissense‑Default, AlphaMissense‑Optimized, and the SGM‑Consensus (Likely Benign). Pathogenic predictions are reported by polyPhen‑2 HumDiv, polyPhen‑2 HumVar, and SIFT. High‑accuracy assessments further support a benign outcome: AlphaMissense‑Optimized predicts benign, and the SGM‑Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) also indicates likely benign. Foldetta stability analysis is unavailable. Overall, the preponderance of evidence points to a benign effect, which is consistent with the ClinVar uncertain status rather than contradicting it.

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. High‑accuracy assessments show AlphaMissense‑Optimized as benign, Foldetta as uncertain, and the SGM Consensus as unavailable. Consequently, the overall prediction profile is mixed, but the most reliable high‑accuracy evidence points toward a benign effect. Therefore, the variant is most likely benign, which aligns with its ClinVar classification and does not contradict the reported status.

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. | |||||||||
| c.844T>A | C282S 2D  3DClick to see structure in 3D Viewer AIThe SynGAP1 missense variant C282S is listed in ClinVar with an “Uncertain” status and is not reported in gnomAD. Prediction tools that indicate a benign effect include REVEL, whereas the majority of other in‑silico predictors (premPS, PROVEAN, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, SIFT, ESM1b, FATHMM, AlphaMissense‑Default, AlphaMissense‑Optimized, and the SGM‑Consensus) all classify the variant as pathogenic. Stability‑based methods (FoldX, Rosetta, and Foldetta) return uncertain results and are therefore not considered evidence for or against pathogenicity. High‑accuracy assessments show AlphaMissense‑Optimized as pathogenic, the SGM‑Consensus as Likely Pathogenic, and Foldetta as uncertain. Based on the preponderance of pathogenic predictions, the variant is most likely pathogenic, which does not contradict its current ClinVar “Uncertain” classification.

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

Asp330-Ala322, res. Thr305-Asn315), packs against the hydrophobic side chain of Ile205 at the end of the anti-parallel β sheet in the PH domain. In the variant simulations, the iso-butyl side chain of Leu318 is unable to do the same, potentially weakening the PH and C2 domain association. Importantly, the residue swap could also affect loop formation during folding, as proline can make tighter turns than leucine. Because the residue swap could affect the C2 domain stability, it could also negatively impact the SynGAP-membrane association. | ||||||||

High‑accuracy methods specifically give AlphaMissense‑Optimized as uncertain, SGM‑Consensus as pathogenic, and Foldetta as pathogenic.

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

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

The Ω loop potentially plays a crucial role in the SynGAP-membrane complex association, stability, and dynamics.

The iso-propyl side chain of Val464 is similarly hydrophobic but considerably smaller than the original phenyl ring of Phe464. To compensate for the size difference, neighboring residues need to fill in the gap in the variant simulations.The phenolic side chain of Tyr428, located at the middle bend of an α helix (res.

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

Ala533-Val560). In the WT simulations, the guanidinium side chain of Arg544 forms a salt bridge with the carboxylate groups of Glu548 on the same α-helix, and with Glu651 and Glu656 on an opposing α-helix (res. Glu666-Asp644). In the variant simulations, the pyrrolidine side chain of Pro544 cannot form any of the salt bridges that Arg544 does in the WT, potentially weakening the tertiary structure assembly. Additionally, Pro544 lacks the amide group, and thus, unlike Arg544 in the WT, is unable to form a hydrogen bond with the carbonyl of Gln540. This disruption breaks the continuity of the secondary structure element, causing the α-helix to bend slightly in the variant simulations. These negative structural effects could be more pronounced during protein folding and are likely to be undermined in the MD simulations. | ||||||||||

Arg563-Glu578), forms salt bridges with the carboxylate groups of Asp463 and Asp467, and it also hydrogen bonds with the hydroxyl group of Ser466 on an opposing α-helix (res. Ala461-Phe476) in the WT simulations. In the variant simulations, the imidazole ring of His575 (in its neutral epsilon protonated form) cannot form the same salt bridges as the guanidinium group of the non-mutated Arg575. Instead, His575 only forms weak hydrogen bonds with the hydroxyl groups of Ser466 and Ser571.

Glu617-Asn635), forms hydrogen bonds with Gln631 on the same α helix and with the hydroxyl side chain of Ser590 on an opposing α helix (res. Glu582-Met603).In the variant simulations, the side chain of Ser635 is shorter than asparagine and thus prefers to hydrogen bond with the carbonyl group of Gln631 on the same helix and, to a lesser extent, with Ser590 compared to Asn635 in the WT. 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.

Prediction tools that agree on a benign effect include REVEL, SIFT, AlphaMissense‑Default, and AlphaMissense‑Optimized. Those that predict a pathogenic impact are Rosetta, PROVEAN, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, and FATHMM. Predictions that are inconclusive or uncertain are FoldX, ESM1b, and premPS.

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

Additionally, the thiol side chain of Cys weakly hydrogen bonds with the carbonyl group of Leu543 in the same α-helix. In the variant simulations, the bulkier phenol ring of Tyr547, with its polar hydroxyl group, is less suited for the hydrophobic space. Consequently, it moves outside and forms a hydrogen bond with the carbonyl group of Phe652 in the neighboring α-helix (res. Glu666-Asp644). This causes the two helices to slightly separate, negatively affecting the secondary structure integrity of the latter helix. These negative structural effects could be more pronounced during protein folding and are likely to be undermined in the MD simulations. | |||||||||

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. | |||||||

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

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.

Gly502-Tyr518 and Ala533-Val560). In the WT simulations, the carboxylate side chain of Glu519 does not make any specific interactions. Accordingly, the Ala residue swap does not show any negative structural effects in the variant simulations. However, it should be noted that Glu519 faces the missing part of the N-terminal in the model, and thus its potential role in maintaining the tertiary structure might be de-emphasized in the current model. | |||||||||||

Overall, the predictions are mixed, with a slight bias toward benign outcomes from the majority of tools and the high‑accuracy AlphaMissense‑Optimized and Foldetta results. Therefore, the variant is most likely benign based on the current computational evidence, which is consistent with its ClinVar benign classification.

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 on a slightly α-helical loop (res. Glu478-Thr488) preceding another α helix (res. Ala461-Phe476).In the variant simulations, the neutral carboxamide group of the Gln581 side chain cannot form any of these salt bridges. Instead, it packs hydrophobically against Met477 and Ile587 or forms hydrogen bonds sporadically with nearby residues (e.g., Asp583, Arg587). Thus, although no drastic changes are observed in the variant simulations, the residue swap could weaken the tertiary structure assembly. | ||||||||
| c.2200C>T | P734S 2D AIThe SynGAP1 missense variant P734S is listed in ClinVar with an uncertain significance (ClinVar ID 2283225.0) and is present in the gnomAD database (gnomAD ID 6‑33441665‑C‑T). Functional prediction tools uniformly classify the variant as benign: REVEL, PROVEAN, polyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, FATHMM, AlphaMissense‑Default, and AlphaMissense‑Optimized all report benign effects. No tool predicts pathogenicity. The high‑accuracy consensus methods corroborate this benign assessment: AlphaMissense‑Optimized is benign, and the SGM Consensus (majority vote from AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN) indicates a likely benign outcome. Foldetta, a protein‑folding stability predictor combining FoldX‑MD and Rosetta outputs, did not provide a result for this variant, so its status is unavailable. Overall, the computational evidence strongly supports a benign classification, which is consistent with the ClinVar uncertain status rather than contradicting it.

The residue swap could affect complex formation with the GTPase and its activation. In the WT simulations, the carboxylate group of Glu486 forms salt bridges with Arg485 and Arg475 on the preceding α-helix (res. Ala461-Phe476). In the variant simulations, Lys486 does not form any specific interactions. Although the amino group of the Lys486 side chain cannot form these salt bridges, no negative effects on the protein structure are observed.

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, although the carboxamide group of the Gln573 side chain can hydrogen bond with the carboxylate group of Glu582 or the hydroxyl group of Ser668, these interactions are not as coordinated, stable, or strong as those of the positively charged Arg573.

Thr305-Asn315), hydrogen bonds with the carboxylate groups of Glu270 and Asp304 in the anti-parallel β strand and the adjacent β hairpin loop, respectively. In the variant simulations, the methyl group of the Ala305 side chain cannot hydrogen bond with either of the acidic residues, which could weaken the integrity of the tertiary structure and the β hairpin loop. Indeed, the guanidinium group of Arg299 does not acquire its central hairpin loop position due to the residue swap.β hairpins are potential nucleation sites during the initial stages of protein folding, so even minor changes in them could be significant. Due to its location near the membrane surface, the residue swap could also affect the C2 loop dynamics and SynGAP-membrane association. However, this is beyond the scope of the solvent-only simulations to unravel. | |||||||||

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 REVEL, Rosetta, Foldetta, premPS, SIFT, ESM1b, AlphaMissense‑Default, and AlphaMissense‑Optimized. Tools that predict a pathogenic effect are PROVEAN, polyPhen‑2 HumDiv, polyPhen‑2 HumVar, and FATHMM. The high‑accuracy AlphaMissense‑Optimized score is benign, the SGM Consensus (majority vote from AlphaMissense‑Default, ESM1b, FATHMM, PROVEAN) is inconclusive due to a 2‑vs‑2 split, and Foldetta predicts a benign effect. No other high‑accuracy or folding‑stability methods provide additional evidence. Overall, the majority of predictions support a benign impact, which does not contradict the ClinVar Uncertain status.

Ala533-Val560). The carboxamide group of Asn556 forms hydrogen bonds with nearby residues such as Lys553 and Cys552. 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. However, the residue swap does not cause negative structural effects during the simulations. | |||||||||

High‑accuracy assessments show AlphaMissense‑Optimized as benign, SGM Consensus as pathogenic, and Foldetta (combining FoldX‑MD and Rosetta outputs) as uncertain. No other stability or functional scores are available. Overall, the preponderance of evidence points to a pathogenic effect, which does not contradict the ClinVar uncertain status but suggests a leaning toward pathogenicity.

Ala322-Asp330), faces outward and frequently forms a salt bridge with the carboxylate group of the Asp288 side chain, which is part of a β strand end (res. Met289-Pro298). In the variant simulations, the indole ring of the Trp324 side chain cannot maintain a similar interaction with the negatively charged carboxylate side chain of Asp288, potentially compromising the folding of the anti-parallel β sheet assembly. However, the residue swap does not appear to negatively impact the protein structure or its integrity based on the simulations. | ||||||||
| c.1485A>C | E495D 2D 3DClick to see structure in 3D Viewer AISynGAP1 missense variant E495D is listed in ClinVar with an uncertain significance (ClinVar ID 2000233.0) and is not reported in gnomAD. Functional prediction tools cluster into two groups: benign predictions from SIFT and ESM1b, and pathogenic predictions from REVEL, PROVEAN, polyPhen‑2 (HumDiv and HumVar), FATHMM, AlphaMissense‑Default, and AlphaMissense‑Optimized. The high‑accuracy consensus (SGM Consensus) derived from AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN classifies the variant as likely pathogenic. AlphaMissense‑Optimized also predicts pathogenicity, whereas Foldetta, which integrates FoldX‑MD and Rosetta outputs, remains uncertain. Overall, the majority of evidence points to a pathogenic effect, which does not contradict the ClinVar uncertain status but suggests a higher likelihood of deleterious impact.

Leu489-Glu519), and its carboxylate group forms salt bridges with the neighboring Lys492 and with Arg596 on an opposing α-helix (res. Glu582-Met603) in the WT simulations. In the variant simulations, the acidic carboxylate side chain of Asp495 can also form salt bridges with both Lys492 and Arg596. However, the shorter side chain of aspartate tends to favor forming a salt bridge with the nearby Arg499 on the same α-helix instead. Asp495 might not maintain the salt bridge with Arg596 on the opposing α-helix as efficiently as Glu495 in the WT, potentially weakening the tertiary structure. Regardless, the potential negative effect is likely to be minor, with no deleterious effects observed on the protein structure during the simulations. However, due to its location at the GAP-Ras interface, the effect of the residue swap on SynGAP-Ras complex formation or GTPase activation cannot be fully addressed using the SynGAP solvent-only simulations. | ||||||||||
| c.2702C>T | A901V 2D AIThe SynGAP1 missense variant A901V is listed in ClinVar (ID 934469.0) with an “Uncertain” clinical significance and is present in the gnomAD database (gnomAD ID 6‑33443254‑C‑T). All evaluated in‑silico predictors classify the substitution as benign: REVEL, PROVEAN, PolyPhen‑2 (HumDiv and HumVar), SIFT, ESM1b, FATHMM, AlphaMissense‑Default, and AlphaMissense‑Optimized. No tool reports a pathogenic or likely pathogenic outcome. High‑accuracy assessments corroborate this benign prediction: AlphaMissense‑Optimized is benign, and the SGM Consensus (majority vote of AlphaMissense‑Default, ESM1b, FATHMM, and PROVEAN) is “Likely Benign.” Foldetta, a protein‑folding stability method combining FoldX‑MD and Rosetta outputs, did not provide a result for this variant. Overall, the computational evidence strongly supports a benign effect, which does not contradict the ClinVar “Uncertain” status.

Ile205-Pro208), is replaced by another hydrophobic residue, phenylalanine. Both the phenyl group of Phe200 and the branched iso-butyl hydrocarbon sidechain of Leu200 occupy an inward hydrophobic niche (e.g., Leu246, Val222, Phe231) during the simulations. However, since the model ends abruptly at the N-terminus, no definite conclusions can be drawn from the simulations. | |||||||||

Met414-Glu436), packs against hydrophobic residues in an interhelix space (e.g., Met430, Ala707, Leu711). In the variant simulations, the sec-butyl group of Ile434 is able to form the same hydrophobic interactions. Accordingly, the residue swap does not negatively affect the protein structure based on the simulations. | ||||||||
