Holoprosencephaly is a fetal abnormality of the brain in which the brain of the fetus remains underdeveloped and does not divide into two hemispheres which is the actual norm. The survival of the patient is related to the integrity of the brainstem, which regulates vital aspects, such as temperature, blood pressure and cardiorespiratory function. Other symptoms may include visual impairment, lack of growth, deafness, blindness, spastic quadriparesis (paralysis), and intellectual deficits. PVHH has long been considered to be prenatally lethal.
