Genes affected

FZD7 (HGNC:4045): (frizzled class receptor 7) Members of the 'frizzled' gene family encode 7-transmembrane domain proteins that are receptors for Wnt signaling proteins. The FZD7 protein contains an N-terminal signal sequence, 10 cysteine residues typical of the cysteine-rich extracellular domain of Fz family members, 7 putative transmembrane domains, and an intracellular C-terminal tail with a PDZ domain-binding motif. FZD7 gene expression may downregulate APC function and enhance beta-catenin-mediated signals in poorly differentiated human esophageal carcinomas. [provided by RefSeq, Jul 2008]

The c.1097G>A (p.G366D) alteration is located in exon 1 (coding exon 1) of the FZD7 gene. This alteration results from a G to A substitution at nucleotide position 1097, causing the glycine (G) at amino acid position 366 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
