Genes affected

ANO10 (HGNC:25519): (anoctamin 10) The transmembrane protein encoded by this gene belongs to the anoctamin family of calcium-activated chloride channels, also known as the transmembrane 16 family. The encoded protein contains eight transmembrane domains with cytosolic N- and C-termini. Defects in this gene may cause autosomal recessive spinocerebellar ataxia-10. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2016]

ACMG classification

Verdict is Pathogenic. Variant got 11 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 3-43555341-TA-T is Pathogenic according to our data. Variant chr3-43555341-TA-T is described in ClinVar as [Pathogenic]. Clinvar id is 31060.Status of the report is no_assertion_criteria_provided, 0 stars.
