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]

Significance:Pathogenic
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This sequence change creates a premature translational stop signal (p.Gln405*) in the ANO5 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in ANO5 are known to be pathogenic (PMID: 21186264, 23606453, 25891276, 30919934). This variant is present in population databases (rs368970223, gnomAD 0.003%). This premature translational stop signal has been observed in individuals with autosomal recessive limb girdle muscular dystrophy (PMID: 25891276). ClinVar contains an entry for this variant (Variation ID: 285742). For these reasons, this variant has been classified as Pathogenic. -

Significance:Pathogenic
Review Status:criteria provided, single submitter
Collection Method:clinical testing

A Heterozygous Nonsense variant c.1213C>T in Exon 13 of the ANO5 gene that results in the amino acid substitution p.Gln405* was identified. The observed variant has a minor allele frequency of 0.00002/0.00003% in gnomAD exomes and genomes, respectively. The severity of the impact of this variant on the protein is high, based on the effect of the protein and REVEL score . Rare Exome Variant Ensemble Learner (REVEL) is an ensembl method for predicting the pathogenicity of missense variants based on a combination of scores from 13 individual tools: MutPred, FATHMM v2.3, VEST 3.0, PolyPhen-2, SIFT, PROVEAN, MutationAssessor, MutationTaster, LRT, GERP++, SiPhy, phyloP, and phastCons. The REVEL score for an individual missense variant can range from 0 to 1, with higher scores reflecting greater likelihood that the variant is disease-causing. ClinVar has also classified this variant as Pathogenic (Variant ID: 285742). The observed variant has previously been reported in the patient affected with muscular dystrophy (Hicks D et.al) Based on the above evidence this variant has been classified as Pathogenic according to the ACMG guidelines. -
