Gaucher's disease is a lysosomal storage disease resulting from glycocerebroside GLUCOCEREBROSIDE (1) accumulation in macrophages due to a genetic deficiency of the enzyme glucocerebrosidase. It may occur in patients of all ages. The most severe form, Type 2 Gaucher's Disease occurs in infants who die in the first years of life (with rapidly progressive neurologic deterioration). The condition is passed from generation to generation through autosomal recessive inheritance.
