Genes affected
WDR48 (HGNC:30914): (WD repeat domain 48) The protein encoded by this gene has been shown to interact with ubiquitin specific peptidase 1 (USP1), activating the deubiquitinating activity of USP1 and allowing it to remove the ubiquitin moiety from monoubiquitinated FANCD2. FANCD2 is ubiquitinated in response to DNA damage. [provided by RefSeq, Sep 2016]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 30, 2024The c.1291A>G (p.I431V) alteration is located in exon 13 (coding exon 13) of the WDR48 gene. This alteration results from a A to G substitution at nucleotide position 1291, causing the isoleucine (I) at amino acid position 431 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
