Genes affected
WDR3 (HGNC:12755): (WD repeat domain 3) This gene encodes a nuclear protein containing 10 WD repeats. WD repeats are approximately 30- to 40-amino acid domains containing several conserved residues, which usually include a trp-asp at the C-terminal end. Proteins belonging to the WD repeat family are involved in a variety of cellular processes, including cell cycle progression, signal transduction, apoptosis, and gene regulation.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 05, 2023The c.791G>A (p.R264Q) alteration is located in exon 8 (coding exon 7) of the WDR3 gene. This alteration results from a G to A substitution at nucleotide position 791, causing the arginine (R) at amino acid position 264 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
