PITX2 (Paired Like Homeodomain 2): PITX2 is a transcription factor that plays a crucial role in the development of multiple organ systems, including the eyes, heart, and abdominal organs. It is involved in establishing the body’s left-right asymmetry. Mutations in PITX2 are linked to Axenfeld-Rieger syndrome, a condition that affects the eyes and other organs. Understanding PITX2 is important for developmental biology and for exploring treatments for related congenital disorders.
