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]

This sequence change replaces methionine, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 871 of the ANO5 protein (p.Met871Leu). This variant is present in population databases (rs189233047, gnomAD 0.04%). This variant has not been reported in the literature in individuals affected with ANO5-related conditions. ClinVar contains an entry for this variant (Variation ID: 468845). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt ANO5 protein function with a negative predictive value of 95%. 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. -
