Study Population

Study population will include approximately equal proportions of subjects with OTC deficiency, GSDIa, and Wilson Disease

You may qualify if:

  • Diagnosis of OTC deficiency, GSDIa, or Wilson Disease.
  • Provide informed consent after the nature of the study has been explained, and prior to any research-related procedures.

You may not qualify if:

  • Prior exposure to an AAV-based gene therapy.
