General Discussion

Holoprosencephaly is the failure of the prosenceplon section of the forebrain (the part of the brain in the fetus that evolves into parts of the adult brain) to develop. This causes defects in the development of the middle of the face and in brain structure and function. Closely set eyes (hypotelorism), missing front teeth (incisors), and an abnormally small head (microcephaly) may occur. Rarely, severely affected infants are born with cyclopia (the eyes fused into one) and a deformed or absent nose.
