Phenotypic variation between siblings with Metachromatic Leukodystrophy

MR of childhood metachromatic leukodystrophy.

PURPOSE To investigate the MR findings of childhood metachromatic leukodystrophy (MLD). METHODS Nine MR imaging studies in seven children (five girls and two boys, 10 to 32 months old) with MLD were evaluated retrospectively for the extent and progression of white matter abnormalities and the presence of contrast enhancement. RESULTS All seven cases showed symmetric, confluent high signal i...

Metachromatic leukodystrophy: two sides of a coin.

Adult-type metachromatic leukodystrophy mimicking multiple sclerosis.

recessive lysosomal storage disease caused by a deficiency of arylsulphatase A (ASA). It is characterized by accumulation of sulphatide in the white matter in the central nervous system and peripheral nerves1. The disease is divided in four subtypes, according to onset, severity and progression of the disease: late infantile (before age 4), early juvenile (age 4 to 6), late juvenile (age 6 to 1...

Metachromatic Leukodystrophy Clinical, Biological and Therapeutic Aspects

Scholz’s disease or metachromatic leukodystrophy (MLD) is a lysosomal storage disease caused by a deficiency in arylsulfatase A (ARSA: EC 3.1.6.8). This enzyme is responsible for the degradation of sulfatides commonly called cerebroside-3-sulfate or 3-O sulfogalactosylceramide in galactocerebroside and sulfate. The success of hydrolysis of these sphingolipids by ARSA necessarily depends on the ...

Metachromatic leukodystrophy: genetics, pathogenesis and therapeutic options.

UNLABELLED Metachromatic leukodystrophy is a lysosomal storage disease caused by the deficiency of arylsulphatase A (ASA). This leads to storage of the membrane lipid sulphatide, which is abundant in myelin. A pathological hallmark of the disease is demyelination, causing various and ultimately lethal neurological symptoms. Today more than 110 mutations in the ASA gene have been identified, of ...
