Metachromatic Leukodystrophy (MLD) Overview

Metachromatic leukodystrophy (MLD), or globoid cell leukodystrophy, is a genetic disorder characterized by the accumulation of lipids and other storage materials in cells within the central nervous system's white matter and peripheral nerves. The primary cause of metachromatic leukodystrophy is the deficiency of arylsulfatase A activity, often resulting from mutations in the arylsulfatase A gene (ARSA gene) located on chromosome 22q13.3-qter. Notably, two alleles, A and I, contribute to roughly half of the cases and lead to distinct clinical manifestations of the disease. In some instances, the sphingolipid activator protein SAP-B (saposin B) deficiency causes this condition due to mutations in the prosaposin gene (PSAP gene). MLD, classified as a lysosomal storage disease, arises from the incapacity to break down sulfated glycolipids, particularly galactosyl-3-sulfate ceramides, due to insufficient lysosomal enzyme activity, primarily arylsulfatase A. This enzyme deficiency primarily results from arylsulfatase A (ARSA gene) mutations. During the metabolic process, sulfated glycolipids are transformed into galactocerebroside by Arylsulfatase A. It's crucial to distinguish metachromatic leukodystrophy from other lysosomal storage diseases that exhibit similar symptoms, including those with arylsulfatase A pseudodeficiency. Genetic mutation analysis or evaluation of radiolabeled sulfatide fibroblast uptake and accumulation can aid in distinguishing arylsulfatase A pseudodeficiency. Metachromatic leukodystrophy is a progressive ailment, with symptoms deteriorating over time. Individuals with MLD condition typically experience a loss of muscle and cognitive functions as the disease advances. The prognosis and lifespan vary depending on the age of diagnosis:

1. Late infantile form: This form carries a poor prognosis, with patients typically succumbing to the disease within five to six years.
2. Juvenile form: Progression is slower in this variant, often allowing patients to survive until early adulthood.
3. Adult form: In this form, the disease course may remain stable or exhibit gradual progression.

Currently, no curative treatments are available for metachromatic leukodystrophy. The primary focus of management revolves around enhancing the quality of life through symptom control. Supportive care is essential for addressing neurocognitive and neuropsychiatric disturbances, seizures, dystonias, spasticity, feeding difficulties, and constipation. Common complications include neurocognitive decline (leading to dementia), blindness (such as optic atrophy), malnutrition, aspiration pneumonia, and, in the late infantile form, early mortality (within 5-6 years).
