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.

The c.262G>A (p.E88K) alteration is located in exon 2 (coding exon 2) of the OTUD6B gene. This alteration results from a G to A substitution at nucleotide position 262, causing the glutamic acid (E) at amino acid position 88 to be replaced by a lysine (K). Based on data from the Genome Aggregation Database (gnomAD) database, the OTUD6B c.262G>A alteration was observed in 0.004% (11/282486) of total alleles studied, with a frequency of 0.04% (10/24966) in the African subpopulation. This amino acid position is not well conserved in available vertebrate species. The in silico prediction for the p.E88K alteration is inconclusive. Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
