GM2 Gangliosidosis, Sandhoff Disease, Tay Sachs Disease
Conditions
Brief summary
This study is to continue Long-Term Follow-Up of Patients who were previously treated with AXO-AAV-GM2 Gene Therapy as treatment for Tay-Sachs or Sandhoff Disease to follow the subjects through 5 years after their initial gene therapy treatment.
Detailed description
Subjects will be contacted bi-annually for a total of five years following the administration of AXO-AAV-GM2 for the collection of clinical information, especially pertaining to de novo cancer, neurologic, rheumatologic, and hematologic/immunologic disorders. This will be done to comply with FDA Recommendations and NIH Guidelines for long-term follow-up for research involving gene therapy with AAV Vectors.
Interventions
Participants who received AXO-AAV-GM2 will be tracked in long term follow up
