To establish the diagnosis, two of the three features must be present. All three are only present in 30% of affected individuals. Neuroradiologically, this syndrome is defined by agenesis of the interhemispheric septum pellucidum, schizencephaly, hydranencephaly, and holoprosencephaly. Clinically, other important features include mild to severe developmental delay, seizures, visual impairment, sleep disturbance, precocious puberty, microgenitalia (especially in males), obesity, anosmia, sensorineural hearing loss, and cardiac anomalies.
