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 was made for transcript

Our verdict: Likely_pathogenic. The variant received 7 ACMG points.

PVS1

Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 1.3909554 fraction of the gene. Cryptic splice site detected, with MaxEntScore 7.5, offset of 15, new splice context is: tctacatgttgtgtttttAGtta. Cryptic site results in inframe change. If cryptic site found is not functional and variant results in exon loss, it results in frameshift change.

PM2

Very rare variant in population databases, with high coverage;

PP5

Variant 11-22279542-AG-A is Pathogenic according to our data. Variant chr11-22279542-AG-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 283199.
