Sonic hedgehog signaling is essential for the proper development of the forebrain, eye, and face. Disruption of this signaling pathway can lead to holoprosencephaly, a condition characterized by the failure of the forebrain to divide properly into two hemispheres, resulting in a single telencephalon and a single eye. The other signaling pathways listed are important for various aspects of development, but they are not directly involved in the formation of the forebrain and eye.
