Diagnosis of I-cell disease usually can be made by the specific patterns of enzyme distribution: deficicnt intracellular, but excessive extracellular, enzymes. A six month old female infant was found to have bilateral congenital dislocation of hips, devlopmental delay, coarsening of facial appearance and dysostosis multiplex. In view of the very early onset of discase, I-cell disease was suspected. Lysosomal enzyme tests (including alpha- mannosidase, alpha-fucosidase, beta- glucuronidase and beta- galactosidase) were performed on the leukocytes, skin fibroblasts, plasma and media from fibroblast cultures. All activities of the enzymes were low in both leukocytes and fibroblasts, but were 10-to 70-fold higher than normal in plasma, and high in culture media. Both the clinical and laboratory findings here were consistent with a diagnosis of I-cell disease.#0427# |
