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 GeneticsDec 13, 2022The c.668C>T (p.T223M) alteration is located in exon 7 (coding exon 7) of the WDR48 gene. This alteration results from a C to T substitution at nucleotide position 668, causing the threonine (T) at amino acid position 223 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
