Extractions: Causes, incidence, and risk factors: 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: Leukodystrophy, also called "the leukodystrophies," refers to a group of genetic disorders that are characterized by the imperfect growth or development of the white matter or myelin sheath covering nerve fibers in the brain. Specific leukodystrophies include metachromatic leukodystrophy, Krabbe leukodystrophy, adrenoleukodystrophy, Pelizaeus-Merzbacher disease, Canavan disease, Alexander disease, Zellweger syndrome, Refsum disease, and cerebrotendinous xanthomatosis. The most common signs seen in most leukodystrophies include gradual changes in an infant or child who previously appeared well. Changes may appear in body tone, movements, gait, speech, ability to eat, vision, hearing, behavior, memory, or thought processes. The symptoms, which vary according to the specific type of leukodystrophy, may be difficult to recognize in the early stages of the disease.

Extractions: Clamorous news Yesterday on Nature Medicine, March 2001 Vol. 7 No. 3 Pag. 310-316, appeared the scientific paper on gene theraphy of Metachromatic Leukodystrophy using lentiviral vectors, which were able to transport the healthy ASA enzyme in the brain of mice with this disease, dissolving the noxious fats in both the brain hemispheres, and inducing the regression of the disease in these animals. The disease Metachromatic Leukodystrophy is a severe neurological disorder affecting the Central and the peripherical nervous system. In its more severe form the disease leads to infirmity and, soon after the beginning of the symptoms, to death. The disorder is due to a defect in the gene coding for the Arilsulfatase A enzyme, which avoid the excessive storage of sphyngolipids (noxious fats) in the neurons.

Extractions: *For Medical Professionals only, registration required Metachromatic leukodystrophy, a progressive autosomal recessive white matter lysosomal disease caused by a deficiency of the enzyme arylsulphatase A. The diagnosis is based on the finding of enzyme activity of arylsulphatase A in the urine and peripheral leukocytes. There are three principal forms: late infantile (presenting at the age 23 years), juvenile (presenting at 46 years), and the adult variant. The late infantile form is the most common. The child presents with difficulty in walking, marked by frequent falls within the second and third year of life. The disease progresses quickly with poor speech, mental deterioration, and hypertonia, which develops into decerebrate and decorticate posture within 36 months. Seizures are common. In the juvenile form, symptoms do not usually develop until 4 years. The clinical picture is similar to the late infantile form, except that the child is old enough to show behavioural disturbances as well. Pathologically, symmetrical demyelination with sparing of the U-fibres is found. Metachromatic sulphatides accumulate in the central and peripheral nervous system.

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. In the adult form, symptoms, which begin after age 16, may include impaired concentration, depression, psychiatric disturbances, ataxia, tremor, and dementia. Seizures may occur in the adult form, but are less common than in the other forms.

Extractions: metachromatic leukodystrophy Metachromatic leukodystrophy is an autosomal recessive disorder of sphingolipid metabolism caused by a deficiency of aryl-sulfatase A. The result is an accumulation of lipids such as galactosyl sulfatide. The disorder may be diagnosed prenatally by amniocentesis and assay of the aryl-sulfatase A activity.
