Leigh Syndrome global patient registry

Help us bring patients, families, and researchers together to gain a better understanding of Leigh Syndrome. If you or a family member has been diagnosed anywhere in the world with Leigh Syndrome, please enroll in the patient registry to make an important contribution to Leigh Syndrome research. 


The Cure Mito Foundation is partnering with Sanford CoRDS to create the registry. Sanford CoRDS supports and enables rare disease communities to build robust registries, providing researchers with the information they need to drive research forward. 

For more information about the registry please read IRB-approved Frequently Asked Questions.
