What is Metachromatic Leukodystrophy?
Enzymes in the body assist in the breakdown of substances entering the body from outside. In the absence or deficiency of some enzymes, the body will not break down a substance. In this case, the substance stays in the body and accumulates and the accumulated substance causes various complications.
Metachromatic leukodystrophy occurs due to the absence of the enzyme arylsulfatase A in the body. Arylsulfatase A is responsible for breaking down fats. In the absence of this enzyme, fats that cannot be broken down begin to accumulate in the cells of the kidney, brain, spinal cord and nervous system. Fats accumulating here cause damage.
MLD (metachromatic leukodystrophy) is a rare disease. It is inherited and some children are carriers only.
