Inclusion Criteria:

• Male or females between 8 and 50 years of age at the time of signing theinformed consent form.
• Willing to adhere to protocol as evidenced by written informed consent orparental permission and subject assent.
• Clinical confirmed diagnosis of Leber congenital amaurosis (LCA) andmolecular diagnosis of LCA due to RPE65 mutations.
