What is (are) Krabbe Disease ?
Krabbe disease is a rare, inherited metabolic disorder in which harmful amounts of lipids (fatty materials such as oils and waxes) build up in various cells and tissues in the body and destroys brain cells. Krabbe disease, also known as globoid cell leukodystrophy, ischaracterized by the presence of globoid cells (cells that have more than one nucleus) that break down the nerves protective myelin coating. Krabbe disease is caused by a deficiency of galactocerebrosidase, an essential enzyme for myelin metabolism. The disease most often affects infants, with onset before age 6 months, but can occur in adolescence or adulthood. Symptoms include severe deterioration of mental and motor skills, muscle weakness, hypertonia (inability of a muscle to stretch), myoclonic seizures (sudden, shock-like contractions of the limbs), and spasticity (involuntary and awkward movement). Other symptoms may include irritability, unexplained fever, blindness, difficulty with swallowing, and deafness.
