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]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -5 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.030847281).

BS1

Variant frequency is greater than expected in population sas. GnomAdExome4 allele frequency = 0.0000267 (39/1461886) while in subpopulation SAS AF = 0.000406 (35/86258). AF 95% confidence interval is 0.0003. There are 1 homozygotes in GnomAdExome4. There are 25 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces alanine, which is neutral and non-polar, with glycine, which is neutral and non-polar, at codon 510 of the DIS3L2 protein (p.Ala510Gly). This variant is present in population databases (rs377321022, gnomAD 0.03%). 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: 574482). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬†is likely to be tolerated. 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. -
