Extractions: Subscribe now >> Metachromatic leukodystrophy (MLD) is a genetic disorder caused by a deficiency of the enzyme arylsulfatase A. It is one of a group of genetic disorders called the leukodystrophies that affect growth of the myelin sheath, the fatty coveringwhich acts as an insulatoron nerve fibers in the brain. There are three forms of MLD: late infantile, juvenile, and adult. In the late infantile form, which is the most common, onset of symptoms begins between ages 6 months and 2 years. The infant is usually normal at birth, but eventually loses previously gained abilities. Symptoms include hypotonia (low muscle tone), speech abnormalities, loss of mental abilities, blindness, rigidity (uncontrolled muscle tightness), convulsions, impaired swallowing, paralysis, and dementia. Symptoms of the juvenile form begin between ages 4 and 14, and include impaired school performance, mental deterioration, ataxia, seizures, and dementia.

Causes, incidence, and risk factors Return to top Metachromatic leukodystrophy (MLD) is transmitted as an autosomal recessive trait. MLD has a wide range of symptoms. As with many other storage diseases, there are forms of early and delayed onset (late infant, juvenile and adult types). The most common (and the most severe form) is the late infant onset form, which has symptoms such as irritability decreased muscle tone muscle wasting , the loss of the ability to walk. Debility is progressive with blindness seizures , and partial paralysis . Death occurs usually before age 10.
Extractions: Metachromatic leukodystrophy (MLD) is an inherited disease in which fatty substances build up in the brain and spinal cord. This buildup happens in the part of the brain and spinal cord called the white matter, affecting a person's mental development and ability to move in a coordinated way. Most forms of MLD appear in early childhood, but the disease may also occur in adults. It usually leads to progressive paralysis and, in children, early death. MLD is a rare disease, affecting about one in 50,000 people. Traditional forms of treatment have not been very successful at combating MLD. However, promising new approaches from the fields of gene therapy and cell transplantation provide hope for the future. What causes MLD? MLD is caused by an inability to break down sulfatide a fatty substance normally present in the brain. Scientists have traced the development of MLD to a defect in the gene that tells the body how to make an enzyme called arylsulfatase A (ASA). ASA is the enzyme responsible for breaking down sulfatide into smaller, harmless chemicals that can be eliminated or reused by the body. In MLD, the lack of proper ASA enzyme leads to a buildup of sulfatide, which causes a process called demyelination. Demyelination causes the symptoms of MLD affecting communication between nerves in the brain.

Introduction Patterns of Inheritance Adrenoleukodystrophy (ALD)/Adrenomyeloneuropathy (AMN) Aicardi-Goutieres Syndrome ... Zellweger Syndrome INTRODUCTION The leukodystrophies are genetically determined progressive disorders that affect the brain, spinal cord and peripheral nerves. The term leukodystrophy derives from the Greek words "leuko" meaning white and referring to the white matter of the nervous system and "dystrophy" meaning imperfect growth or development. White matter is white to the naked eye because it contains a complex chemical substance called the myelin sheath. Myelin contains a variety of fatty substances or lipids. Its function is to insulate the axon through which nerve impulses are conducted, much as does insulation around an electric wire; the axon being the biological equivalent of the wire. The myelin sheath is a very complex substance. It is made up of at least ten, and probably more distinct chemicals. Each of the leukodystrophies affects one (and only one) of these substances that all affect the myelin sheath in some way, but otherwise, they are totally separate. Leukodystrophy of one type, does not in any way predispose to, or increase the risk of another type of leukodystrophy.

It is a progressive disorder, transmitted by autosomal recessive inheritance. It is associated with the accumulation of sulfatides (ganglioside) in brain, kidney, liver and gall bladder. The metabolic abnormality lies in the absence or reduction of Arylsulfatase A function resulting in sulfatide accumulation and a demyelinating brain disorder. MLD manifests in a late infantile, juvenile and adult form. A progressive dementia is the primary manifestation of the disease. Peripheral neuropathy is a prominent disease manifestation in the late infantile and juvenile forms. Patients with the adult form of MLD may initially present with psychiatric disease or, more rarely, isolated peripheral neuropathy. Unlike X-ALD, MLD demonstrated a close genotype to phenotype correlation with only one form of the disease developing in a particular family. The disorder can be diagnosed by detecting sulfatide accumulation in urine. Arylsulfatase activity can be assayed in fibroblasts, but one must take care to distinguish between real and pseudodeficiency.
