Invitae | RCV001869219 | SCV002254735 | uncertain significance | Charcot-Marie-Tooth disease axonal type 2F | 2022-09-07 | criteria provided, single submitter | clinical testing | In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Experimental studies are conflicting or provide insufficient evidence to determine the effect of this variant on HSPB1 function (PMID: 23643870, 28000086). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). ClinVar contains an entry for this variant (Variation ID: 637260). This missense change has been observed in individuals with clinical features of HSPB1-related conditions (PMID: 18952241, 25088881). This variant is not present in population databases (gnomAD no frequency). This sequence change replaces lysine, which is basic and polar, with glutamine, which is neutral and polar, at codon 141 of the HSPB1 protein (p.Lys141Gln). |
