Variant summary

Our verdict is Likely benign. Variant got -3 ACMG points: 2P and 5B. PM2 BP4_Strong BP7

The NM_001382637.1(OTUD7A):​c.1134T>G​(p.Leu378=) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

• Frequency: Genomes: not found (cov: 32)
• Consequence: OTUD7A NM_001382637.1 synonymous
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: -1.41

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 Likely_benign. Variant got -3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.91).
• BP7: Synonymous conserved (PhyloP=-1.41 with no splicing effect.
