Enzyme testing is the preferred test to detect affected individuals. DNA testing may be used to confirm affected status. Gaucher disease (OMIM 230800) is an autosomal recessive disorder caused by a decrease in the levels of the enzyme glucocerebrosidase. Decreased levels of glucocerebrosidase can result in visceral changes, such as organomegaly and thrombocytopenia, and skeletal changes, such as bone lesions.

There are three subtypes of Gaucher disease. Type 1 is the most common subtype. Individuals affected with type 1 may have onset of symptoms in adolescence, though some remain asymptomatic well into adulthood. Type 1 is effectively treated through enzyme replacement therapy.
