Genes affected

ANO7 (HGNC:31677): (anoctamin 7) This prostate-specific gene encodes a cytoplasmic protein, as well as a polytopic membrane protein which may serve as a target in prostate cancer diagnosis and immunotherapy. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Aug 2011]

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.05480787).

The c.302C>G (p.A101G) alteration is located in exon 3 (coding exon 3) of the ANO7 gene. This alteration results from a C to G substitution at nucleotide position 302, causing the alanine (A) at amino acid position 101 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
