Genotype assignments in a family with the pseudo arylsulfatase a deficiency trait without metachromatic leukodystrophy. 1984

H Kihara, and W E Meek, and A L Fluharty

Two children in a family with five siblings were investigated because of low levels of fibroblast arylsulfatase A activity. Neither child had metachromatic leukodystrophy (MLD) and they were diagnosed as having benign pseudo arylsulfatase A deficiency trait (PD). Analysis of arylsulfatase A subunit profiles in fibroblasts provided data for genotype assignments for each family member. Father and mother were assigned an n/pd and n/mld phenotype, respectively. The low enzyme siblings were both assigned pd/mld; two of the three normal enzyme siblings were assigned an n/n phenotype and one an n/mld.

UI MeSH Term Description Entries
D007966 Leukodystrophy, Metachromatic An autosomal recessive metabolic disease caused by a deficiency of CEREBROSIDE-SULFATASE leading to intralysosomal accumulation of cerebroside sulfate (SULFOGLYCOSPHINGOLIPIDS) in the nervous system and other organs. Pathological features include diffuse demyelination, and metachromatically-staining granules in many cell types such as the GLIAL CELLS. There are several allelic and nonallelic forms with a variety of neurological symptoms.

D002553 Cerebroside-Sulfatase An enzyme that catalyzes the hydrolysis of cerebroside 3-sulfate (sulfatide) to yield a cerebroside and inorganic sulfate. A marked deficiency of arylsulfatase A, which is considered the heat-labile component of cerebroside sulfatase, has been demonstrated in all forms of metachromatic leukodystrophy (LEUKODYSTROPHY, METACHROMATIC).
