Maroteaux-Lamy syndrome in a large consanguineous kindred: biochemical and immunological studies.
We describe a large consanguineous German-Acadian ("Cajun") family from a rural area in Louisiana in which 11 persons in two generations had the Maroteaux-Lamy syndrome. The mutant arylsulfatase B enzyme in this family was similar to the mutant enzyme in previously studied families in its cross-reactivity with specific antibodies to the enzyme, but it differed in both its electrophoretic mobility and its residual enzymatic activity. These findings indicate that a different mutational event leading to Maroteaux-Lamy syndrome occurred in this family.
