Gaucher Disease is a medical condition where fat builds up in certain organs. This study is about collecting information on people with this disease. There's no new treatment involved, just regular doctor visits to see how the disease affects them. The main goal is to learn more about how Gaucher disease changes over time, to help doctors make better treatment plans.

The study also has a special section for pregnant women with Gaucher disease. Here, the focus is on understanding pregnancy and baby outcomes with this condition. Participants will have their health checked by their own doctors, and no new treatments will be tested. Information will be gathered about the pregnancy and baby growth up to three years old.

To join, you just need a doctor's confirmation that you have Gaucher disease. Pregnant women need to sign a form saying they agree to share their medical information. There are no reasons that would exclude someone from joining.

• The study is ongoing with no set end date.
• No new treatments are given; only regular doctor visits are needed.
• This study is purely observational, meaning it just collects data without changing treatment.
