Rare Disease Information

Rare Disease Database

Enhancements to NORD’s Rare Disease Database and website were made possible through a grant from the Anthem Foundation, the charitable arm of Anthem, Inc.

NORD’s Rare Disease Database provides brief introductions for patients and caregivers to specific rare diseases. Medical experts and representatives of patient organizations who would like to assist NORD in developing reports on topics not currently covered in this database may write to [email protected].
