Epidemiology
The National Gaucher Foundation (United States) states that the incidence of Gaucher's disease is about 1 in 20,000 live births. Around 1 in 100 people in the general U.S. population is a carrier for type 1 Gaucher's disease, giving a prevalence of 1 in 40,000. Among Ashkenazi Jews the rate of carriers is considerably higher, at roughly 1 in 15.
Type 2 Gaucher's disease shows no particular preference for any ethnic group.
Type 3 Gaucher's disease is especially common in the population of the Northern Swedish region of Norrbotten where the incidence of the disease is 1 in 50,000.
