WNT3A is a gene that plays a crucial role in the Wnt signaling pathway, which is important for cell communication and development. This gene produces a protein that helps regulate various biological processes, including cell growth, differentiation, and tissue repair. Mutations or alterations in the WNT3A gene can lead to developmental disorders and have been linked to certain diseases, including cancer. Understanding WNT3A and its functions can provide insights into how cells interact and develop, which is essential for advancing medical research and therapies.
