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 Benign. Variant got -7 ACMG points.

PVS1

Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.048367593 fraction of the gene. Cryptic splice site detected, with MaxEntScore 4.3, offset of -31, new splice context is: tgtcagctcaccttgtgcAGtgt. Cryptic site results in frameshift change. If cryptic site found is not functional and variant results in exon loss, it results in inframe change.

BP6

Variant 17-13011784-T-C is Benign according to our data. Variant chr17-13011784-T-C is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 235643.We mark this variant Likely_benign, oryginal submissions are: {Uncertain_significance=1, Benign=2, Likely_benign=1}.

BS1

Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00257 (391/152290) while in subpopulation AFR AF= 0.00876 (364/41560). AF 95% confidence interval is 0.00802. There are 3 homozygotes in gnomad4. There are 187 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.

BS2

High Homozygotes in GnomAd4 at 3 AR gene
