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: Benign. The variant received -7 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.24419028).

BP6

Variant 2-232238628-G-A is Benign according to our data. Variant chr2-232238628-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 410753.

BS1

Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.0000919 (14/152324) while in subpopulation SAS AF = 0.00145 (7/4830). AF 95% confidence interval is 0.000679. There are 0 homozygotes in GnomAd4. There are 9 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
