WNT7B (Wnt Family Member 7B) is a gene that plays a key role in the Wnt signaling pathway, which controls essential cellular processes such as growth, differentiation, and programmed cell death. WNT7B is particularly important in embryonic development, bone formation, and blood vessel development. Disruptions in WNT7B signaling have been associated with conditions such as cancer, fibrosis, and developmental disorders.
