Genes affected

OTUD6B (HGNC:24281): (OTU deubiquitinase 6B) This gene encodes a member of the ovarian tumor domain (OTU)-containing subfamily of deubiquitinating enzymes. Deubiquitinating enzymes are primarily involved in removing ubiquitin from proteins targeted for degradation. This protein may function as a negative regulator of the cell cycle in B cells.

Collection Method: clinical testing

The c.202C>G (p.P68A) alteration is located in exon 2 (coding exon 2) of the OTUD6B gene. This alteration results from a C to G substitution at nucleotide position 202, causing the proline (P) at amino acid position 68 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
