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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingGenetic Services Laboratory, University of ChicagoNov 23, 2021DNA sequence analysis of the USP45 gene demonstrated a sequence change, c.1794T>G, which results in the creation of a premature stop codon at amino acid position 598, p.Tyr598*. This sequence change is predicted to result in an abnormal transcript, which may be degraded, or may lead to the production of a truncated USP45 protein with potentially abnormal function. This sequence change has been described in the gnomAD database in one individual which corresponds to a population frequency of 0.00040% (db SNP rs766826756). This sequence change has not previously been described in individuals with USP45-related disorders. The functional significance of this sequence change is not known at present and its contribution to this individual’s disease phenotype cannot definitively be determined. Biallelic pathogenic variants in USP45 may be associated with Leber congenital amaurosis (PMID: 30573563). -
