Genes affected

WDR18 (HGNC:17956): (WD repeat domain 18) This gene encodes a member of the WD repeat protein family. WD repeats are minimally conserved regions of approximately 40 amino acids typically bracketed by gly-his and trp-asp (GH-WD), which may facilitate formation of heterotrimeric or multiprotein complexes. Members of this family are involved in a variety of cellular processes, including cell cycle progression, signal transduction, apoptosis, and gene regulation. [provided by RefSeq, Jul 2008]

The c.241G>C (p.G81R) alteration is located in exon 2 (coding exon 2) of the WDR18 gene. This alteration results from a G to C substitution at nucleotide position 241, causing the glycine (G) at amino acid position 81 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
