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]

This sequence change affects a donor splice site in intron 3 of the ANO10 gene. It is expected to disrupt RNA splicing. Variants that disrupt the donor or acceptor splice site typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in ANO10 are known to be pathogenic (PMID: 25089919). This variant is present in population databases (rs765592794, gnomAD 0.008%). Disruption of this splice site has been observed in individual(s) with spinocerebellar ataxia (PMID: 30515630). ClinVar contains an entry for this variant (Variation ID: 210186). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. -
