Study Type : Observational
Estimated Enrollment : 1000 participants
Observational Model: Cohort
Time Perspective: Prospective
Actual Study Start Date : August 20, 2018
Estimated Primary Completion Date : August 2021
Estimated Study Completion Date : August 2021

Patients with GM1/GM2-Gangliosidosis or high-grade suspicion for GM1/GM2-Gangliosidosis

Primary Outcome Measures :
  1. Development of a new MS-based biomarker for the early and sensitive diagnosis of GM1/GM2-Gangliosidosis from blood [ Time Frame: 24 months ]
    New methods, like mass-spectrometry give a good chance to characterize specific metabolic alterations in the blood of affected patients that allow diagnosing in the future the disease earlier, with a higher sensitivity and specificity.

Secondary Outcome Measures :
  1. Testing for clinical robustness, specificity and long-term stability of the biomarker [ Time Frame: 36 months ]
    the goal of the study to identify and validate a new biochemical marker from the blood of the affected patients helping to benefit other patients by an early diagnose and thereby with an earlier treatment.

Biospecimen Retention:   Samples With DNA

For the development of the new biomarkers using the technique of Mass-spectometry, maximal 10 ml blood will be taken via using a dry blood spot filter card. To proof the cor-rect GM1/GM2 diagnosis in those patients where up to the enrollment into the study no genetic testing has been done, sequencing of GM1/GM2 will be done.

The analyses will be done at the Centogene AG Am Strande 7 18055 Rostock Germany
