Genes affected

ANO5 (HGNC:27337): (anoctamin 5) This gene encodes a member of the anoctamin family of transmembrane proteins. The encoded protein is likely a calcium activated chloride channel. Mutations in this gene have been associated with gnathodiaphyseal dysplasia. Alternatively spliced transcript variants have been described. [provided by RefSeq, Nov 2009]

The ANO5 c.2498T>A (p.Met833Lys) missense variant has been reported in three studies in which it is found in three unrelated individuals affected with muscular dystrophy who had high levels of creatine kinase, including one who carried the variant in a homozygous state and two who carried the variant in a compound heterozygous state with known or suspected null variants in trans (van der Kooi et al. 2013; Liewluck et al. 2013; Savarese et al. 2015). The p.Met833Lys variant was absent from 52 control individuals (Savarese et al. 2015) and present in a heterozygous state in three unaffected first-degree relatives of probands (van der Kooi et al. 2013; Liewluck et al. 2013). The p.Met833Lys variant is reported at a frequency of 0.001085 in the Ashkenazi Jewish population of the Genome Aggregation Database. Based on the combined clinical evidence, the p.Met833Lys variant is classified as likely pathogenic for ANO5-Related Disorders. This variant was observed by ICSL as part of a predisposition screen in an ostensibly healthy population. -

This sequence change replaces methionine, which is neutral and non-polar, with lysine, which is basic and polar, at codon 833 of the ANO5 protein (p.Met833Lys). This variant is present in population databases (rs142073798, gnomAD 0.1%). This missense change has been observed in individual(s) with limb girdle or distal muscular dystrophy (PMID: 23607914, 23663589, 25891276). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 285338). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt ANO5 protein function with a positive predictive value of 80%. This variant disrupts the p.Met833 amino acid residue in ANO5. Other variant(s) that disrupt this residue have been observed in individuals with ANO5-related conditions (PMID: 31350120), which suggests that this may be a clinically significant amino acid residue. For these reasons, this variant has been classified as Pathogenic. -
