cerebral palsy
A disorder caused by injury to the cerebral area of the brain that occurs before or during birth or in the first few months after birth. Damage to the cerebrum may cause paralysis (palsy) in one or more parts of the body.

Apert syndrome
Apert Syndrome is a genetic defect and falls under the broad classification of craniofacial/limb anomalies. It can be inherited from a parent who has Apert, or may be a fresh mutation. It occurs in approximately 1 per 160,000 to 200,000 live births. Apert syndrome is primarily characterized by specific malformations of the skull, midface, hands, and feet.

Eye Birth Defect
Anophthalmia/microphthalmia, congenital cataracts, glaucoma

Cardiovascular Birth Defect
Conotruncal heart defects, septal heart defects, obstructive heart defects, atrioventricular septal defects, single ventricle, anomalous pulmonary venous return, heterotaxy, Ebstein malformation.

brain tumor
An abnormal growth of tissue in the brain

Central nervous system Birth Defect
Neural tube defects, hydrocephaly, holoprosencephaly, Dandy-Walker malformation

Canavan disease
Canavan disease is an inherited disorder of the central nervous system in which affected individuals cannot break down a compound called N-acetyl-L-aspartic acid (NAA). Canavan disease is one of a group of genetic disorders called the eukodystrophies.

cerebellum
The portion of the brain mainly responsible for balance and coordination.

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.
