Labcorp Genetics (formerly Invitae), Labcorp RCV001203530 SCV001374699 pathogenic X-linked myopathy with postural muscle atrophy 2022-12-02 criteria provided, single submitter clinical testing This sequence change replaces cysteine, which is neutral and slightly polar, with arginine, which is basic and polar, at codon 101 of the FHL1 protein (p.Cys101Arg). For these reasons, this variant has been classified as Pathogenic. This variant disrupts the p.Cys101 amino acid residue in FHL1. Other variant(s) that disrupt this residue have been observed in individuals with FHL1-related conditions (PMID: 19171836), which suggests that this may be a clinically significant amino acid residue. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. ClinVar contains an entry for this variant (Variation ID: 935026). This variant is also known as p.Cys100Arg. This missense change has been observed in individual(s) with FHL1-related disease and reducing body myopathy (PMID: 28694073; Invitae). In at least one individual the variant was observed to be de novo. This variant is not present in population databases (gnomAD no frequency).
