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]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -3 ACMG points.

PM4
Nonframeshift variant in NON repetitive region in NM_018127.7.
BS1
Variant frequency is greater than expected in population nfe. gnomad4_exome allele frequency = 0.00162 (2353/1456472) while in subpopulation NFE AF= 0.00181 (2003/1108126). AF 95% confidence interval is 0.00174. There are 27 homozygotes in gnomad4_exome. There are 1184 alleles in male gnomad4_exome subpopulation. Median coverage is 32.

Gene duplications are expected to disrupt gene function; however, it is unclear whether this duplication is disruptive to the ELAC2 gene, or is merely duplicated adjacent to the original xxxx gene or located elsewhere in the genome (Mazzarella, R and Schlessinger, D Genome Res 1998;8:1007-1021). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
Combined oxidative phosphorylation defect type 17 Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpOct 20, 2022This variant, c.2353_2415dup, results in the insertion of 21 amino acid(s) of the ELAC2 protein (p.Arg785_Asp805dup), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (no rsID available, gnomAD 0.2%), including at least one homozygous and/or hemizygous individual. 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: 408865). 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. -
