Understanding rare disease science and policy should not require a degree in genetics or medicine. The Explainer Library has been created to help every reader follow essential concepts with confidence. Each guide is short, plain language, and focused on one topic at a time. The aim is to remove confusion, reduce technical barriers, and support informed reading across all sections of Rare Disease Watch.
You will find clear explanations of topics such as the meaning of a rare disease, how genetic testing works, why some conditions run in families, how clinical research is designed, and what terms like prevalence, biomarkers, and endpoints actually signify in practice. These resources are written to support patients, families, researchers, students, and anyone curious about this complex field.
New explainers are added regularly and updated as understanding evolves. Readers can browse individual topics or search for the concepts they want to explore further.
