Further study details as provided by Florian Eichler, Massachusetts General Hospital:

Primary Outcome Measures:
  • Change in Brief Ataxia Rating Scale over six months [ Time Frame: baseline and 6 month visits ]
    Ataxia rating scale incorporating gait, dysarthria, and coordination

Secondary Outcome Measures:
  • Change over six months in metabolite levels seen on magnetic resonance spectroscopy [ Time Frame: baseline and 6 months ]
  • Change over six months in lipid levels found in the cerebrospinal fluid [ Time Frame: baseline and 6 months ]

Biospecimen Retention:   Samples With DNA
Blood will be collected to establish lymphoblast cell lines. Cerebrospinal fluid will also be collected from some subjects.

Estimated Enrollment: 10
Study Start Date: April 2016
Estimated Primary Completion Date: April 2018 (Final data collection date for primary outcome measure)
Late Onset GM2 Gangliosidosis
10-15 subjects with Late Onset GM2 Gangliosidosis

  Show Detailed Description


Ages Eligible for Study:   7 Years and older   (Child, Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Subjects diagnosed with Late Onset GM2 Gangliosidosis

Inclusion Criteria:

  • The subject must have a confirmed diagnosis of Late Onset GM2 Gangliosidosis as defined by (a) absent to near-absent beta-hexosaminidase enzymatic activity in the serum or white blood cells or (b) mutation analysis of the HEXA and HEXB genes to distinguish pseudo deficiency alleles from disease-causing alleles
  • The subject must be older than 7 years of age

Exclusion Criteria:

  • If a patient is very severely affected by the disease, the PI will assess whether it is in the best interest of the patient to exclude them from the study for their own comfort and well being. In cases where the PI deems it appropriate, severely affected patients will be excluded. Patients under the age of 7 years will be excluded from this study.
