Variant summary

Our verdict is Likely benign. The variant received -3 ACMG points: 2P and 5B. PM2BP4_StrongBP6

The NM_152383.5(DIS3L2):​c.1430T>G​(p.Leu477Arg) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000712 in 1,614,122 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. L477F) has been classified as Uncertain significance.

Genes affected
DIS3L2 (HGNC:28648): (DIS3 like 3'-5' exoribonuclease 2) The protein encoded by this gene is similar in sequence to 3'/5' exonucleolytic subunits of the RNA exosome. The exosome is a large multimeric ribonucleotide complex responsible for degrading various RNA substrates. Several transcript variants, some protein-coding and some not, have been found for this gene. [provided by RefSeq, Mar 2012]

Sep 24, 2024
PreventionGenetics, part of Exact Sciences
Significance:Uncertain significance
Review Status:no assertion criteria provided
Collection Method:clinical testing

The DIS3L2 c.1430T>G variant is predicted to result in the amino acid substitution p.Leu477Arg. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.012% of alleles in individuals of European (Non-Finnish) descent in gnomAD. This variant has been reported as benign (1) and uncertain (2) in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/241960/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
