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 Benign. Variant got -8 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.8).
BP6
Variant 2-232335787-G-T is Benign according to our data. Variant chr2-232335787-G-T is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 416353.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=1, Benign=1, Uncertain_significance=1}.
BP7
Synonymous conserved (PhyloP=0.07 with no splicing effect.
BS1
Variant frequency is greater than expected in population mid. gnomad4_exome allele frequency = 0.000139 (194/1398180) while in subpopulation MID AF= 0.000718 (4/5570). AF 95% confidence interval is 0.000245. There are 0 homozygotes in gnomad4_exome. There are 98 alleles in male gnomad4_exome subpopulation. Median coverage is 30. This position pass quality control queck.
