Genes affected

OTUD6A (HGNC:32312): (OTU deubiquitinase 6A) Deubiquitinating enzymes (DUBs; see MIM 603478) are proteases that specifically cleave ubiquitin (MIM 191339) linkages, negating the action of ubiquitin ligases. DUBA2 belongs to a DUB subfamily characterized by an ovarian tumor (OTU) domain.[supplied by OMIM, May 2008]

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=0.1608307).

The c.602A>C (p.D201A) alteration is located in exon 1 (coding exon 1) of the OTUD6A gene. This alteration results from a A to C substitution at nucleotide position 602, causing the aspartic acid (D) at amino acid position 201 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
