Gaucher disease (GD) type 1 is the most common lysosomal storage disease and the most common genetic disorder among Ashkenazi Jews. The majority of patients with GD present with unexplained splenomegaly and/or thrombocytopenia, and the disorder often affects children; consequently, haematologists and paediatricians are ideally placed to diagnose this condition. Prompt management of GD type 1 using enzyme-replacement therapy or substrate reduction therapy can reduce the risk of developing long-term GD complications and reverse many of the initial signs/symptoms, thereby improving both quality and duration of life. Treatment is most effective when initiated early; consequently, a prompt diagnosis is essential. Despite this, the average time to diagnosis following the onset of clinical symptoms is 4 years. Reasons for the delay include the heterogeneous nature of the disease, together with a lack of awareness of rare haematological disorders and the benefits of early treatment. Indeed, studies show that only 20% of haematologists consider GD type 1 in their differential diagnosis for patients presenting with splenomegaly and/or thrombocytopenia. To help raise awareness of GD, reduce the diagnostic delay and prevent unnecessary tissue biopsies, simple diagnostic algorithms and screening tools have been developed and validated, both in adults and in children.
