About this study
This study is being conducted to better understand the natural course of GM1 gangliosidosis, GM2 gangliosidoses and Gaucher disease Type 2 (GD2). Information is planned to be gathered on at least 180 patients with GM1 gangliosidosis, GM2 gangliosidoses, and Gaucher Disease type 2. Retrospective data collection is planned for at least 150 deceased patients (Group A). Group B is for patients alive at the time of enrollment. In Group B it is planned to prospectively collect more comprehensive data from at least 30 patients. The purpose of this study is to collect relevant information for a adequate design of a potential subsequent research program in these diseases.
In this study no therapy is being offered.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Group A - Retrospective data collection | Participants with a confirmed diagnosis, either deceased patients or patients whose survival status is not known at enrollment. | |
| Group B - Prospective data collection | Participants who are alive at enrollment. Data collection is retrospective for the time between birth and enrollment visit, and data collection is prospective from the enrollment visit onwards. Visits are performed as per local standard of care. |
