Genes affected

OTUD1 (HGNC:27346): (OTU deubiquitinase 1) Deubiquitinating enzymes (DUBs; see MIM 603478) are proteases that specifically cleave ubiquitin (MIM 191339) linkages, negating the action of ubiquitin ligases. DUBA7 belongs to a DUB subfamily characterized by an ovarian tumor (OTU) domain.[supplied by OMIM, May 2008]

ENSG00000287124 (HGNC:):

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.029208481).

The c.67C>T (p.P23S) alteration is located in exon 1 (coding exon 1) of the OTUD1 gene. This alteration results from a C to T substitution at nucleotide position 67, causing the proline (P) at amino acid position 23 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
