text: <unk>  <unk>  is a degenerative disorder of myelin, a complex fatty neural tissue that insulates many nerves of the central and peripheral nervous systems. Without myelin, nerves are unable to conduct an impulse, leading to increasing disability as myelin destruction increases and intensifies. The victims of<unk>  are always male, and the disease begins its expression around the ages 5 to 10. The disease is due to an X-linked inheritance of peroxisomes that cannot properly process long chain fatty acids in the brain.<unk>  is a type of leukodystrophy, disorders affecting the growth and/or development of myelin. Leukodystrophies are different from demyelinating disorders such as multiple sclerosis where myelin is formed normally but is lost by immunologic dysfunction or for other reasons.
