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]

The c.1163G>A (p.R388Q) alteration is located in exon 10 (coding exon 9) of the DIS3L2 gene. This alteration results from a G to A substitution at nucleotide position 1163, causing the arginine (R) at amino acid position 388 to be replaced by a glutamine (Q). The p.R388Q alteration is predicted to be tolerated by in silico analysis. Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

The DIS3L2 c.1163G>A variant is predicted to result in the amino acid substitution p.Arg388Gln. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.015% of alleles in individuals of East Asian descent in gnomAD (http://gnomad.broadinstitute.org/variant/2-233075074-G-A). This variant is interpreted as uncertain in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/580061). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 388 of the DIS3L2 protein (p.Arg388Gln). This variant is present in population databases (rs754008215, gnomAD 0.02%). 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: 580061). 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 with a negative 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. -
