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

Verdict is Uncertain_significance. Variant got 2 ACMG points.

This variant results in a change from valine to methionine at codon 531. This variant was not identified in the literature nor was it identified in ClinVar or Cosmic. In-silico predictions show Pathogenic computational verdict based on 8 pathogenic predictions from DANN, EIGEN, FATHMM-MKL, M-CAP, MutationAssessor, MutationTaster, PolyPhen and SIFT vs 5 benign predictions from BayesDel_addAF, DEOGEN2, LIST-S2, MVP and PrimateAI. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) do not predict a difference in splicing. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time. Therefore, this variant is classified as a variant of uncertain -
