Fzd5 knockout mice die in utero around E10.75 due to defects in yolk sac and placental angiogenesis, with markedly reduced endothelial cell proliferation (BrdU labeling) prior to morphological changes; Fzd5 specifically synergized with Wnt2, Wnt5a, and Wnt10b in ectopic axis induction in Xenopus, establishing it as a Wnt receptor required for endothelial growth in the yolk sac. |

Fzd5 and Gcm1 form a positive feedback loop in chorionic trophoblast: Gcm1 upregulates Fzd5 specifically at branching initiation sites, and elevated Fzd5 expression maintains Gcm1 expression via nuclear β-catenin signaling. Fzd5-mediated signaling induces disassociation of cell junctions (downregulating ZO-1, claudin 4, claudin 7) for branching initiation and upregulates Vegf in chorion trophoblast cells. |

A heterozygous frameshift mutation in FZD5 (p.Ala219Glufs*49) produces a truncated protein that retains the WNT-ligand-binding (cysteine-rich) domain but lacks the transmembrane domain; this truncated protein is secreted from cells and acts as a dominant-negative FZD5 receptor, antagonizing both canonical and non-canonical WNT signaling, causing coloboma and microphthalmia in zebrafish and disruption of retinal neural epithelium apical junctions in mouse. |

Genome-wide CRISPR-Cas9 screens in RNF43-mutant PDAC cells identified FZD5 as the specific Wnt receptor required for proliferation in these tumors; anti-FZD5 antibodies inhibited growth in vitro and as xenografts in vivo, and the functional specificity of FZD5 could not be explained by differential protein expression patterns across the ten FZD receptors. |
