Holoprosencephaly (HPE) is the failure of the prosencephalon (a region of the brain in the fetus that develops into parts of the adult brain), or forebrain, to develop normally. Instead of the normal completely distinct left and right halves of the forebrain, there is an abnormal continuity between the two sides. Mental retardation is associated and seizures are often present. Children with holoprosencephaly may also have defects in the development of the middle of the face such as closely set eyes (hypotelorism), tooth abnormalities (single central incisor), cleft lip/palate, and an abnormally small head (microcephaly) may occur.
