Genes affected

FZD2 (HGNC:4040): (frizzled class receptor 2) This intronless gene is a member of the frizzled gene family. Members of this family encode seven-transmembrane domain proteins that are receptors for the wingless type MMTV integration site family of signaling proteins. This gene encodes a protein that is coupled to the beta-catenin canonical signaling pathway. Competition between the wingless-type MMTV integration site family, member 3A and wingless-type MMTV integration site family, member 5A gene products for binding of this protein is thought to regulate the beta-catenin-dependent and -independent pathways.

The c.26G>A (p.R9H) alteration is located in exon 1 (coding exon 1) of the FZD2 gene. This alteration results from a G to A substitution at nucleotide position 26, causing the arginine (R) at amino acid position 9 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
