Genes affected

USP26 (HGNC:13485): (ubiquitin specific peptidase 26) This gene encodes a member of the ubiquitin-specific processing (UBP) family of proteases and is a deubiquitinating enzyme (DUB) with His and Cys domains. It is specifically expressed in testis tissue. Mutations in this gene have been associated with Sertoli cell-only syndrome and male infertility. [provided by RefSeq, Jul 2008]

The c.2624G>A (p.R875H) alteration is located in exon 1 (coding exon 1) of the USP26 gene. This alteration results from a G to A substitution at nucleotide position 2624, causing the arginine (R) at amino acid position 875 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
