German measles

a disease that is caused by the rubella virus and that produces symptoms similar to measles, although it is less contagious. A woman who develops German measles during pregnancy has a 25% chance of giving birth to a child with congenital rubella. The rate of malformation in the fetus ranges from a low of 6% if the virus is contracted during the 3rd month of pregnancy to as high as 50% in the 1st month. The birth defects include malformations of the eyes, ears, and central nervous system (see congenital rubella syndrome). Also called rubella.

metachromatic leukodystrophy

metachromatic leukodystrophy

an autosomal recessive disorder (see recessive allele) characterized by deficiency or absence of the enzyme arylsulfatase A, which results in loss of myelin in the nervous system and accumulation of cerebroside sulfate (a type of myelin lipid) within the white matter of the central nervous system. Loss of motor function and deterioration in mental ability most commonly develop after the 1st year of life (late infantile form), but symptoms may also appear between 3 and 10 years of age (juvenile form) or around age 30 (adult form).
