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 OTUD6B c.133C>G variant is predicted to result in the amino acid substitution p.Leu45Val. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0064% of alleles in individuals of European (Non-Finnish) descent in gnomAD (http://gnomad.broadinstitute.org/variant/8-92082655-C-G). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
