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 3 ACMG points.

PM1
In a topological_domain Extracellular (size 59) in uniprot entity ANO5_HUMAN there are 7 pathogenic changes around while only 0 benign (100%) in NM_213599.3
PP3
MetaRNN computational evidence supports a deleterious effect, 0.859
BS2

ANO5-Related Muscle Diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingIllumina Laboratory Services, IlluminaJan 13, 2018This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. -
Gnathodiaphyseal dysplasia;C1969785:Autosomal recessive limb-girdle muscular dystrophy type 2L Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJun 13, 2023In 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 expected to disrupt ANO5 protein function. ClinVar contains an entry for this variant (Variation ID: 281308). This variant has not been reported in the literature in individuals affected with ANO5-related conditions. This variant is present in population databases (rs139344099, gnomAD 0.004%). This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 348 of the ANO5 protein (p.Gly348Ser). -
