Genes affected

WDR5B (HGNC:17826): (WD repeat domain 5B) This intronless gene encodes a protein containing several WD40 repeats. WD repeats are approximately 30- to 40-amino acid domains containing several conserved residues, including a trp-asp at the C-terminal end. The encoded protein may mediate protein-protein interactions. [provided by RefSeq, Jul 2008]

The c.503A>G (p.D168G) alteration is located in exon 1 (coding exon 1) of the WDR5B gene. This alteration results from a A to G substitution at nucleotide position 503, causing the aspartic acid (D) at amino acid position 168 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
