The natural history of Gaucher disease type 1 in 31 patients over a median of 15 years: a retrospective study

The natural history of untreated patients with type 1 Gaucher disease (GD1) is not well documented, and there is controversy over when and how to treat such patients, especially if they are only mildly symptomatic. Treatment of GD1 is inconvenient, very costly, and may result in undesirable side effects. We documented the clinical history of 31 untreated patients with GD1 followed in our clinic for 4-26 (median 15) years.
