|Brief Title||Nervous System Degeneration in Glycosphingolipid Storage Disorders|
|Official Title||Investigation of Neurodegeneration in the Glycosphingolipid Storage Disorders|
This study will evaluate children with glycosphingolipid (GSL) storage disorders to investigate brain changes that cause nervous system degeneration. No experimental treatments are offered in this study; participants will receive standard medical care for their disease. The information from this study may help researchers develop new therapies for these disorders and monitor the effects of treatment.
Patients of any age with Tay-Sachs disease, Sandhoff disease, GM1 gangliosidosis, or type 2 Gaucher disease may be eligible for this study.
Participants will be admitted to the NIH Clinical Center for 4 to 5 days every 6 months for a clinical evaluation involving the following tests and procedures:
The GM1 and GM2 gangliosidoses are lysosomal storage disorders that primarily affect the brain and are uniformly fatal. No effective therapy for patients with these diseases has yet been demonstrated. Historically, since these disorders are fatal very little natural history information or disease characterization using modern medical techniques has been collected. This information is vital in order to establish the pattern of disease progression and to identify clinical, biochemical and biophysical markers that can be used as endpoints in future therapeutic trials.
This protocol aims to study the natural history of the GM1 and GM2 gangliosidoses in affected individuals of all ages, races and genders using medical technologies including MRI/MRS, hearing evaluation and auditory evoked response testing, and EEG, as well as subspecialty evaluations in rehabilitative medicine, ophthalmology, speech language pathology, neurology, and psychology. Biomarkers of disease progression will be explored in CSF and blood samples for correlation with disease staging. Fibroblast cultures will be established for testing potential therapeutic agents. We hypothesize that relevant biomarkers will correlate with disease progression and will shed light on the pathophysiology of disease progression in these devastating disorders.
As a means of acquiring additional information, subjects or their parents will also be asked to complete a questionnaire regarding their medical and developmental history, initial clinical presentation of the disease and steps toward diagnosis. At their request, the same questionnaire will be sent to families who do not wish to undergo clinical evaluation at the NIH, who are too unstable to travel, or whose children are already deceased.
