My sister passed away from Moya Moya disease. We would like to send her memorial to the foundation. How and where do we send them.

My condolences for your loss.

The closest I found was this: Disease Information from NORD, National Organization for Rare Disorders, Inc.

I am sorry for your loss - I find nothing other than what "KISS" has posted.
