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]

DIS3L (HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.07338861).

The c.599A>T (p.H200L) alteration is located in exon 5 (coding exon 5) of the DIS3L gene. This alteration results from a A to T substitution at nucleotide position 599, causing the histidine (H) at amino acid position 200 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
