TGFBR2 (Transforming Growth Factor Beta Receptor 2): TGFBR2 is a gene that encodes a key component of the TGF-beta signaling pathway, which regulates cell growth, differentiation, and immune responses. Mutations in TGFBR2 are linked to hereditary conditions like hereditary hemorrhagic telangiectasia (HHT) and may contribute to the development of certain cancers.
