Causes
Leukodystrophy is caused by genetic defects that lead to imperfect growth or development of the myelin sheath that covers the axon. (An axon is a part of the nerve cell.) Each type of leukodystrophy is the result of a certain genetic defect that controls one of the chemicals that make up myelin. Most leukodystrophies are inherited, or passed from parent to child. Others may arise spontaneously.
