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 made for transcript

Verdict is Likely_pathogenic. Variant got 9 ACMG points.

PVS1

Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.

PP5

Variant 11-22274639-CCA-C is Pathogenic according to our data. Variant chr11-22274639-CCA-C is described in ClinVar as [Pathogenic]. Clinvar id is 39277.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr11-22274639-CCA-C is described in Lovd as [Pathogenic].

BS2

High AC in GnomAd4 at 7 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.

For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 39277). This premature translational stop signal has been observed in individual(s) with autosomal recessive limb-girdle muscular dystrophy (PMID: 22402862). This variant is present in population databases (rs746988059, gnomAD 0.03%). This sequence change creates a premature translational stop signal (p.Gln771Alafs*8) 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). -
