Genes affected

OTUD7A (HGNC:20718): (OTU deubiquitinase 7A) The protein encoded by this gene is a deubiquitinizing enzyme and possible tumor suppressor. The encoded protein acts on TNF receptor associated factor 6 (TRAF6) to control nuclear factor kappa B expression. However, this gene is downregulated by SNAIL1 in hepatocellular carcinoma cells, contributing to their progression and malignancy. [provided by RefSeq, Aug 2016]

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=0.088697344).

The homozygous missense variant c.2626G>C, p.Gly876Arg in the OTUD7A gene has not been reported in the available literature. The variant is not presentin the gnomAD database, indicating this is a rare allele. In silicotools, predict conflicting evidence of pathogenicity (PMID: 27268795). Based on the available evidence, the c.2626G>C, p.Gly876Arg variant in the OTUD7A gene is classified as a variant of uncertain significance. -
