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 threonine, which is neutral and polar, with isoleucine, which is neutral and non-polar, at codon 862 of the DIS3L2 protein (p.Thr862Ile). This variant is present in population databases (rs778725551, gnomAD 0.007%). 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. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. ClinVar contains an entry for this variant (Variation ID: 531942). This variant has not been reported in the literature in individuals affected with DIS3L2-related conditions. -

The DIS3L2 p.T862I variant was not identified in the literature but was identified in dbSNP (ID: rs778725551) and ClinVar (classified as uncertain significance by Invitae for Renal hamartomas nephroblastomatosis and fetal gigantism).Â¬â€ The variant was identified in control databases in 3 of 244416 chromosomes at a frequency of 0.00001227 (Genome Aggregation Database March 6, 2019, v2.1.1). The p.T862 residue is conserved in mammals however computational analyses (MUT Assesor, PolyPhen-2, SIFT, MutationTaster, Revel, FATHMM, MetaLR, DANN) do not suggest a high likelihood of impact to the protein; this information is not very predictive of pathogenicity. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (Splice AI exome) do not predict a difference in splicing.Â¬â€ In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance. -
