Watch Queue Queue Indeed, in severe cases, it is important to consider medical limitations as the disease could be fatal. Holoprosencephaly is a congenital brain disorder caused by a failure of an embryo’s forebrain to divide to form bilateral cerebral hemispheres (the left and right halves of the brain), causing defects in the development of the face and in brain structure and function.

Abstract Holoprosencephaly (HPE) is a heterogeneous central nervous system (CNS) anomaly that results from a primary defect in induction and patterning of the rostral neural tube (basal forebrain), leading to varying degrees of incomplete separation of the cerebral hemispheres and facial anomalies. Holoprosencephaly (HPE) is a complex brain malformation resulting from incomplete cleavage of the prosencephalon, occurring between the 18th and the 28th day of gestation and affecting both the forebrain and the face. Most commonly associated with facial abnormalities such as cyclopia, ethmocephaly, cebocephaly, and median cleft lip. The alobar form of holoprosencephaly, which is the most severe form, has the worst prognosis and most children do not survive beyond six months.
