Alexander disease
Alexander disease is considered one of the leukodystrophies, a group of disorders where the primary abnormality is the inability to maintain the fatty covering (myelin) that insulates nerve fibers in the brain. Alexander disease is a rare disorder of the nervous system that usually begins during infancy or early childhood.

brain tumor
An abnormal growth of tissue in the brain
Crouzon syndrome
Many of the signs of Crouzon syndrome result from the early fusion of the skull bones during childhood. Abnormal growth of these bones leads to wide-set, bulging eyes due to shallow eye sockets; eyes that do not point in the same direction (strabismus); a beaked nose; and an underdeveloped upper jaw.
SADDAN
SADDAN (severe achondroplasia with developmental delay and acanthosis nigricans) is a rare inherited disorder of bone growth characterized by skeletal, brain, and skin abnormalities.
Jackson-Weiss syndrome
Many of the characteristic facial features of Jackson-Weiss syndrome result from the premature fusion of the skull bones. The head is unable to grow normally, which can lead to a misshapen skull, widely spaced eyes, and a bulging forehead. Foot abnormalities are the most consistent characteristic, as not all individuals with Jackson-Weiss syndrome have abnormal skull or facial features.
