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]

For these reasons, this variant has been classified as Pathogenic. Loss-of-function variants in ANO5 are known to be pathogenic (PMID: 25891276, 23606453, 21186264). This variant has been reported in combination with another ANO5 variant in an individual affected with pseudo-metabolic myopathy (PMID: 23041008). ClinVar contains an entry for this variant (Variation ID: 468825). This variant is not present in population databases (ExAC no frequency). This sequence change creates a premature translational stop signal (p.Arg50*) in the ANO5 gene. It is expected to result in an absent or disrupted protein product. -
