LEIGH SYNDROME GLOBAL patient registry

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.

Important registry reminders and information 

  • After completing or updating a survey, it is important to hit "Submit". Otherwise your data will not be available for analysis.

  • Registry has a general survey and a Leigh syndrome survey. Both should be completed for data to be included in the analysis. 

  • If diagnosis has been confirmed by genetic testing, please enter genetic mutation in question 4 in the Leigh syndrome survey. If you need help interpreting your genetic report please contact us at

  • If your loved one turns 18, you will be sent an email from CoRDS asking you to re-consent. 3 reminders will be sent. If you don't re-consent, your data will no longer be available.

  • If you are enrolling a participant who has both Leigh syndrome and PDCD, during account creation it is important to select "Leigh Syndrome" and "Pyruvate Dehydrogenase Complex Deficiency (PDCD)" under "Rare disease diagnosis".
