1 in 17 people* will be affected by a rare disease at some point in their lives. This amounts to 3.5 million people in the UK* and 30 million people across Europe (1).
The majority of rare diseases currently have no effective treatment (1).
8 out of 10 rare diseases (3) have a genetic cause and 99% of genetic conditions are classed as rare (4). Often rare diseases are chronic and life-threatening. Rare diseases can be single gene, multifactorial, chromosomal or non-genetic.
On average, it takes over four years (5) to receive an accurate diagnosis of a rare disease.
Rare diseases include rare cancers such as childhood cancers and some other well known conditions, such as cystic fibrosis and Huntington’s disease.
