Genes affected
USP27X (HGNC:13486): (ubiquitin specific peptidase 27 X-linked) This gene encodes a member of the peptidase protein family. The encoded protein functions as a deubiquitinase that is involved in upregulation of the pro-apoptotic Bim protein. This protein may act as a tumor suppressor by increasing levels of Bim to counteract anti-apoptotic signals in cancer cells. Mutations in this gene have been associated with X-linked cognitive disability. [provided by RefSeq, Dec 2016]

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 22, 2023The c.59G>C (p.G20A) alteration is located in exon 1 (coding exon 1) of the USP27X gene. This alteration results from a G to C substitution at nucleotide position 59, causing the glycine (G) at amino acid position 20 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
