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

Classification was made for transcript

Our verdict: Pathogenic. The variant received 12 ACMG points.

PVS1

Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.057142857 fraction of the gene. Cryptic splice site detected, with MaxEntScore 6.1, offset of 35, new splice context is: cgtctggcatcgtgattcAGgtg. Cryptic site results in frameshift change. If cryptic site found is not functional and variant results in exon loss, it results in inframe change.

PM2

Very rare variant in population databases, with high coverage;

PP5

Variant 3-43580474-T-A is Pathogenic according to our data. Variant chr3-43580474-T-A is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 1323906.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
