An improved method for heterozygote identification in feline and human mucopolysaccharidosis VI, arylsulfatase-B deficiency

Enzyme. 1981;26(4):206-10. doi: 10.1159/000459176.

Abstract

An improved method has been developed for the detection of heterozygotes for feline and human mucopolysaccharidosis VI. Arylsulfatase-A and -B activities were assayed in leukocyte extracts following separation of the enzymes by batch chromatography on DEAE cellulose. Determination of arylsulfatase-B specific activities did not permit accurate heterozygote identification, whereas the arylsulfatase-A to arylsulfatase-B activity ratio discriminated all 16 obligate heterozygotes for the feline and human disorders.
