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.

Collection Method: clinical testing

The c.544C>A (p.H182N) alteration is located in exon 5 (coding exon 4) of the WDR3 gene. This alteration results from a C to A substitution at nucleotide position 544, causing the histidine (H) at amino acid position 182 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
