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 made for transcript

Verdict is Likely_benign. Variant got -1 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

BP4

Computational evidence support a benign effect (MetaRNN=0.09213376).

BS1

Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.000158 (24/152332) while in subpopulation AFR AF= 0.000577 (24/41566). AF 95% confidence interval is 0.000398. There are 0 homozygotes in gnomad4. There are 10 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

This sequence change replaces serine, which is neutral and polar, with proline, which is neutral and non-polar, at codon 345 of the DIS3L2 protein (p.Ser345Pro). This variant is present in population databases (rs373488862, gnomAD 0.05%). 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: 410732). 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 disruptive. 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. -
