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]

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Mar 08, 2022 | 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. This variant has not been reported in the literature in individuals affected with ELAC2-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change results in a frameshift in the ELAC2 gene (p.Arg824Serfs*44). While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 3 amino acid(s) of the ELAC2 protein and extend the protein by 40 additional amino acid residues. - |
