Our impact How Your Support Helps Research & innovation Rare diseases A huge 75% of rare diseases affect children. And 30% of these patients will die before their fifth birthday. They don't have to. That's why Birmingham Children’s Hospital is so committed, and why we're going to build the UK's first Rare Diseases Centre for children. We are in a unique position given that the demographic and complexity of the population we serve have a high prevalence of rare diseases. In addition to providing an understanding to the causes of rare diseases the research we hope to conduct in the very near future will also provide a fundamental insight into the causes of common diseases.
