What Is the NORD Rare Disease Database?
The NORD (National Organization for Rare Disorders) Rare Disease Database is an inclusive and comprehensive list of rare diseases. "When you hear hoofbeats, think horses, not zebras" is a medical school phrase that means doctors should consider the most likely diagnosis first, rather than the least likely. In medicine, a zebra represents a rare disease. For this reason, the zebra awareness ribbon pin represents rare diseases and all diseases in this rare disease database list.
Personalized Cause® prints the zebra design on an enamel pin that includes a rubber backing. Zebra awareness pins are available in both a non-personalized and personalized version. We also offer a zebra, pink and blue pin in a personalized and non-personalized version. This is a further reminder of the struggle people face when seeking a rare disease diagnosis. The zebra, pink and blue pins further highlight the struggle with being undiagnosed.
Different Designated Colors for the Same Disease or Disorder
Occasionally, a rare disease has a separate, designated color that is different from the zebra image. When this occurs, please feel free to use either the zebra design or designated color. The purpose of the zebra pin is to be a universal symbol of rare disease designation. Our purpose is not to be judgmental of the color you choose. Please avoid analysis paralysis and worry that you are choosing the wrong color when you make your selection. The choice is yours.
Most importantly, your purpose is to raise awareness. This is especially true for diseases and disorders that get little recognition or may hit close to home. Ultimately, our goal is to help unknown diseases and disorders gain recognition. Again, we do this with the use of a simple, but meaningful, awareness ribbon pin.
What is a Rare Disease as Designated by NORD?
A rare disease, as designated by NORD, is a disease, disorder, illness or condition that affects fewer than 200,000 Americans. In total, there are over 10,000 rare diseases that affect more than 30 million Americans. Because of this, NORD dedicates itself to the identification, treatment, and cure of these diseases. They do this through comprehensive education, advocacy, research, and service programs.
NORD rare diseases present unique challenges for researchers and companies working toward treatments and cures. This is due, in part, to:
- Small patient populations.
- Hard to diagnose or delayed diagnosis due to lack of education and understanding among medical professionals.
- Poor understanding of the natural history of the disease and its progression without intervention.
- No prior pathways to follow, including clinical endpoints that are often unclear.
- Enrollment and retention challenges.
What is an Orphan Drug?
Lastly, let's discuss the purpose of orphan drugs. An orphan drug is a drug intended to treat a condition affecting fewer than 200,000 Americans. Or, which will not be profitable within 7 years following approval by the FDA. An orphan drug is a medication used to treat, prevent, or diagnose a rare disease or condition. In other words, the term "orphan" refers to the fact that these drugs may have been abandoned or "orphaned." This is due to a lack of funding or interest in development.
Special Circumstances for Orphan Drug Approval
However, patients with rare diseases desperately need orphan drugs. The Orphan Drug Act (ODA) passed in 1983. It is designed to encourage the development of orphan drugs by providing financial incentives and other assistance to manufacturers. As a result, the FDA may provide Orphan Drug Designation to a drug or biological product that is being investigated for rare disease use. The ODA has led to the approval of more than 600 orphan drugs.
