FZD8 (Frizzled Class Receptor 8): FZD8 is a gene that encodes a receptor for Wnt signalling proteins. It plays a crucial role in embryonic development and cell signalling pathways. FZD8 is essential for processes such as cell differentiation, proliferation, and polarity. Abnormalities in FZD8 signalling are linked to developmental defects and several types of cancer.
