Genes affected

RNASEL (HGNC:10050): (ribonuclease L) This gene encodes a component of the interferon-regulated 2-5A system that functions in the antiviral and antiproliferative roles of interferons. The protein is involved in innate immunity and is active against multiple RNA viruses, including the influenza and SARS-CoV-2 viruses. Mutations in this gene have been associated with predisposition to prostate cancer and this gene is a candidate for the hereditary prostate cancer 1 (HPC1) allele. [provided by RefSeq, Nov 2021]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -3 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.07341212).

BS2

High AC in GnomAdExome4 at 20 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.

The c.1727G>A (p.C576Y) alteration is located in exon 4 (coding exon 3) of the RNASEL gene. This alteration results from a G to A substitution at nucleotide position 1727, causing the cysteine (C) at amino acid position 576 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
