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]

ANO10 Gene-Disease associations (from GenCC):

• autosomal recessive spinocerebellar ataxia 10

  Inheritance: AR Classification: STRONG, MODERATE, SUPPORTIVE Submitted by: Ambry Genetics, Labcorp Genetics (formerly Invitae), Orphanet

ACMG classification

Our verdict: Pathogenic. The variant received 12 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 3-43576710-C-A is Pathogenic according to our data. Variant chr3-43576710-C-A is described in ClinVar as Pathogenic. ClinVar VariationId is 162018.Status of the report is criteria_provided_single_submitter, 1 stars.

Significance: Pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 162018). This premature translational stop signal has been observed in individual(s) with clinical features of spinocerebellar ataxia (PMID: 25182700). This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Glu382*) in the ANO10 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in ANO10 are known to be pathogenic (PMID: 25089919). -
