Genes affected

USP45 (HGNC:20080): (ubiquitin specific peptidase 45) The protein encoded by this gene is a deubiquitylase that binds ERCC1, the catalytic subunit of the XPF-ERCC1 DNA repair endonuclease. This endonuclease is a critical regulator of DNA repair processes, and the deubiquitylase activity of the encoded protein is important for maintaining the DNA repair ability of XPF-ERCC1.

Collection Method: clinical testing

The c.2222C>T (p.S741L) alteration is located in exon 17 (coding exon 16) of the USP45 gene. This alteration results from a C to T substitution at nucleotide position 2222, causing the serine (S) at amino acid position 741 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
