Gaucher disease is a rare inherited disorder, in which people do not have enough of an enzyme called acid beta-glucosidase, which normally breaks down a fatty waste product called glucosylceramide. Without the enzyme, glucosylceramide builds up in the body, typically in the liver, spleen and bone marrow, which produces the symptoms of the disease: anaemia (low red blood cell counts), tiredness, easy bruising and a tendency to bleed, an enlarged spleen and liver, and bone pain and breaks.
