Rare diseases are conditions that affect a small percentage of the population, typically fewer than 1 in 2,000 individuals. These diseases are often chronic, life-threatening, and have limited treatment options. Research in rare diseases aims to better understand the underlying causes of these conditions, develop new diagnostic tools, and identify potential treatments. Due to the small number of affected individuals, research in rare diseases can be challenging and often requires collaboration between multiple institutions and researchers. The ultimate goal of rare disease research is to improve the quality of life and outcomes for those affected by these conditions.
