USP27X
Chr XXLRubiquitin specific peptidase 27 X-linked
Also known as: MRX105, USP22L, USP27, XLID105
The protein functions as a deubiquitinase that regulates innate antiviral immunity by deubiquitinating CGAS and RIG-I, and stabilizes the pro-apoptotic protein BIM. Mutations cause X-linked intellectual developmental disorder 105 through an X-linked recessive inheritance pattern. The high pLI score (0.92) and low LOEUF score (0.36) indicate strong intolerance to loss-of-function variants, suggesting haploinsufficiency as the likely pathogenic mechanism.
