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. This variant has not been reported in the literature in individuals with DIS3L2-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces glycine with cysteine at codon 877 of the DIS3L2 protein (p.Gly877Cys). The glycine residue is weakly conserved and there is a large physicochemical difference between glycine and cysteine. -
