Currently there are about 7,000 known rare diseases.  To be considered a rare disease by the National Institutes of Health in the United States, each disease has to have fewer than 200,000 diagnosed patients.

It is estimated that 25 million people in the United States are affected by a rare disease.  Unfortunately, less than 5 percent of rare diseases have a treatment.

The SSADH Association works with other Organizations and Consortiums that focus on helping rare disease patient groups. Through these joint efforts we are able to stay involved, leverage research and secure additional available funds.
