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]

ACMG classification

Verdict is Benign. Variant got -7 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.22).
• BP6: Variant 3-39067051-C-T is Benign according to our data. Variant chr3-39067051-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 3040306.Status of the report is no_assertion_criteria_provided, 0 stars.
• BS2: High AC in GnomAd4 at 225 AD gene.
