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]

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. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt DIS3L2 protein function. ClinVar contains an entry for this variant (Variation ID: 1059129). This variant has not been reported in the literature in individuals affected with DIS3L2-related conditions. This variant is present in population databases (rs775531488, gnomAD 0.002%). This sequence change replaces lysine, which is basic and polar, with threonine, which is neutral and polar, at codon 809 of the DIS3L2 protein (p.Lys809Thr). -
