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: 21186264, 23606453, 25891276, 30919934). This variant has not been reported in the literature in individuals with ANO5-related conditions. This variant is present in population databases (rs146341538, ExAC 0.003%). This sequence change creates a premature translational stop signal (p.Arg642*) in the ANO5 gene. It is expected to result in an absent or disrupted protein product. -
