Genes affected

FZD9 (HGNC:4047): (frizzled class receptor 9) Members of the 'frizzled' gene family encode 7-transmembrane domain proteins that are receptors for Wnt signaling proteins. The FZD9 gene is located within the Williams syndrome common deletion region of chromosome 7, and heterozygous deletion of the FZD9 gene may contribute to the Williams syndrome phenotype. FZD9 is expressed predominantly in brain, testis, eye, skeletal muscle, and kidney. [provided by RefSeq, Jul 2008]

The c.334C>T (p.R112W) alteration is located in exon 1 (coding exon 1) of the FZD9 gene. This alteration results from a C to T substitution at nucleotide position 334, causing the arginine (R) at amino acid position 112 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
