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 11-22221136-C-T is Pathogenic according to our data. Variant chr11-22221136-C-T is described in ClinVar as [Pathogenic]. Clinvar id is 536729.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr11-22221136-C-T is described in Lovd as [Pathogenic]. Variant chr11-22221136-C-T is described in Lovd as [Pathogenic]. Variant chr11-22221136-C-T is described in Lovd as [Likely_pathogenic].
BS2
High AC in GnomAdExome4 at 8 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.

Gnathodiaphyseal dysplasia;C1969785:Autosomal recessive limb-girdle muscular dystrophy type 2L Pathogenic:1
Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpMay 15, 2018This sequence change creates a premature translational stop signal (p.Arg74*) in the ANO5 gene. It is expected to result in an absent or disrupted protein product. This variant is present in population databases (rs749645231, ExAC 0.01%). This variant has been reported in individuals affected with limb-girdle muscular dystrophy (LGMD) (PMID: 22742934, 26404900). Loss-of-function variants in ANO5 are known to be pathogenic (PMID: 21186264, 23606453, 25891276). For these reasons, this variant has been classified as Pathogenic. -
