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]

Significance:Uncertain significance

Review Status:no assertion criteria provided

Collection Method:clinical testing

The DIS3L2 c.2031G>A variant is not predicted to result in an amino acid change (p.=). However, this variant is predicted to possibly impact splicing (SpliceAI, Jaganathan K, et al. 2019. PubMed ID: 30661751). To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.039% of alleles in individuals of African descent in gnomAD. This variant is interpreted as likely benign in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/410746/). Although we suspect that this variant may be benign, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
