Genes affected

DIS3L (HGNC:28698): (DIS3 like exosome 3'-5' exoribonuclease) The cytoplasmic RNA exosome complex degrades unstable mRNAs and is involved in the regular turnover of other mRNAs. The protein encoded by this gene contains 3'-5' exoribonuclease activity and is a catalytic component of this complex. [provided by RefSeq, May 2016]

ACMG classification

Verdict is Uncertain_significance. Variant got 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.876

Mar 21, 2023

The c.749T>A (p.V250D) alteration is located in exon 6 (coding exon 6) of the DIS3L gene. This alteration results from a T to A substitution at nucleotide position 749, causing the valine (V) at amino acid position 250 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
