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: Likely_benign. The variant received -3 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.25345427).

BS1

Variant frequency is greater than expected in population amr. GnomAd4 allele frequency = 0.000302 (46/152232) while in subpopulation AMR AF = 0.00301 (46/15278). AF 95% confidence interval is 0.00232. There are 0 homozygotes in GnomAd4. There are 33 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

This sequence change replaces proline with threonine at codon 284 of the ANO10 protein (p.Pro284Thr). The proline residue is highly conserved and there is a small physicochemical difference between proline and threonine. This variant is present in population databases (rs192531429, ExAC 0.03%). This missense change has been observed in individual(s) with clinical features of ANO10-related conditions (Invitae). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
