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]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 1 ACMG points.

PS1

Transcript NM_213599.3 (ANO5) is affected with MISSENSE_VARIANT having same AA change as one Pathogenic present in Lovd

BP4

Computational evidence support a benign effect (MetaRNN=0.09718105).

BS2

High AC in GnomAdExome4 at 28 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.

This variant is present in population databases (no rsID available, gnomAD 0.02%). 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) performed at Invitae indicates that this missense variant is not expected to disrupt ANO5 protein function. ClinVar contains an entry for this variant (Variation ID: 970074). This variant has not been reported in the literature in individuals affected with ANO5-related conditions. This sequence change replaces asparagine, which is neutral and polar, with lysine, which is basic and polar, at codon 882 of the ANO5 protein (p.Asn882Lys). -
