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.

For these reasons, this variant has been classified as Pathogenic. This variant has not been reported in the literature in individuals affected with OTUD6B-related conditions. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This sequence change creates a premature translational stop signal (p.Glu37*) in the OTUD6B gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in OTUD6B are known to be pathogenic (PMID: 28343629). -
