The boy has a bilateral hypoplasia of the optic nerves, absence of the septum pellucidum, corpus callosum, columnae fornicis and comissura anterior fornicis and a cyst in the area of the pineal gland.

Impaired perception of thirst may be due to impaired development of methan brain structures in the hypothalamic region. In combination with diabetes insipidus it led to repeated severe upsets of the internal environment.
