Genes affected

ELAC2 (HGNC:14198): (elaC ribonuclease Z 2) The protein encoded by this gene has a C-terminal domain with tRNA 3′ processing endoribonuclease activity, which catalyzes the removal of the 3' trailer from precursor tRNAs. The protein also interacts with activated Smad family member 2 (Smad2) and its nuclear partner forkhead box H1 (also known as FAST-1), and reduced expression can suppress transforming growth factor-beta induced growth arrest. Mutations in this gene result in an increased risk of prostate cancer. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2009]

This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 642 of the ELAC2 protein (p.Val642Met). This variant is present in population databases (rs149561185, gnomAD 0.05%). This variant has not been reported in the literature in individuals affected with ELAC2-related conditions. ClinVar contains an entry for this variant (Variation ID: 576991). 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. -
