title: Clinical and enzyme studies in Gaucher disease.
abstract: OBJECTIVE
  To study the clinical and biochemical spectrum of Gaucher disease.
  
  
  METHODS
  Assay of beta glucosidase enzyme in leucocytes in patients with splenomegaly, and in chorionic villi for prenatal diagnosis.
  
  
  METHODS
  Hospital-based.
  
  
  METHODS
  Of 13 cases of Gaucher disease, aged 1-6 years, 9 were identified at Delhi and 4 at Bombay.
  
  
  RESULTS
  The enzyme beta-glucosidase was 0.65 nmol/h/mg of protein or less in all the cases in Delhi, and 2.5 nmol/h/mg of protein or less in Bombay. All cases except one belonged to type 1 (hepatosplenomegaly), while one case was of type 2 (neuronopathic). Prenatal diagnosis was carried out in one family and the fetus was found to be affected.
  
  
  CONCLUSIONS
  In children with hepatosplenomegaly and increased acid phosphatase, assay of beta-glucosidase enzyme confirms the diagnosis of Gaucher disease. Diagnosis of the disease is important because enzyme replacement therapy is available and prenatal diagnosis is possible.
