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]

Inborn genetic diseases Uncertain:1
Feb 13, 2025
Ambry Genetics
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.512C>T (p.P171L) alteration is located in exon 6 (coding exon 6) of the ELAC2 gene. This alteration results from a C to T substitution at nucleotide position 512, causing the proline (P) at amino acid position 171 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Combined oxidative phosphorylation defect type 17 Uncertain:1
May 22, 2022
Labcorp Genetics (formerly Invitae), Labcorp
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This variant is present in population databases (rs139453392, gnomAD 0.007%). This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 171 of the ELAC2 protein (p.Pro171Leu). 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: 581028). 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: "Tolerated"; PolyPhen-2: "Possibly 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. -
