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:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 576 of the DIS3L2 protein (p.Arg576Cys). This variant is present in population databases (rs374385308, gnomAD 0.06%). 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: 463070). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is expected to disrupt DIS3L2 protein function with a positive predictive value of 80%. 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. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The DIS3L2 c.1726C>T variant is predicted to result in the amino acid substitution p.Arg576Cys. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.074% of alleles in individuals of Latino descent in gnomAD (http://gnomad.broadinstitute.org/variant/2-233164816-C-T). In ClinVar, this variant is interpreted as uncertain by a single laboratory (https://www.ncbi.nlm.nih.gov/clinvar/variation/463070/). Although we suspect that this variant may be benign (based on minor allele frequency), at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
