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 c.1430T>C (p.M477T) alteration is located in exon 15 (coding exon 15) of the ANO5 gene. This alteration results from a T to C substitution at nucleotide position 1430, causing the methionine (M) at amino acid position 477 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

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. 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on ANO5 protein function. ClinVar contains an entry for this variant (Variation ID: 468832). This variant has not been reported in the literature in individuals affected with ANO5-related conditions. This variant is present in population databases (rs149017832, gnomAD 0.02%). This sequence change replaces methionine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 477 of the ANO5 protein (p.Met477Thr). -
