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]

Variant summary: ANO5 c.2004delG (p.Leu669PhefsX6) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. The variant allele was found at a frequency of 1.2e-05 in 251436 control chromosomes. c.2004delG has been reported in the literature in individuals affected with Limb-Girdle Muscular Dystrophy, Autosomal Recessive. These data indicate that the variant may be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. ClinVar contains an entry for this variant (Variation ID: 285669). Based on the evidence outlined above, the variant was classified as pathogenic. -

This sequence change creates a premature translational stop signal (p.Leu669Phefs*6) 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 (no rsID available, gnomAD 0.003%). This premature translational stop signal has been observed in individual(s) with ANO5-related muscular dystrophy (PMID: 23663589). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 285669). For these reasons, this variant has been classified as Pathogenic. -
