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]

This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 880 of the DIS3L2 protein (p.Glu880Lys). This variant is present in population databases (rs756721316, gnomAD 0.003%). This variant has not been reported in the literature in individuals affected with DIS3L2-related conditions. ClinVar contains an entry for this variant (Variation ID: 578700). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. 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. -
