Brexit and rare diseases: big risk, bigger opportunity?

The UK's planned exit from the EU will leave its national health sector in a very dangerous position. It will also have profound consequences for domestic UK law. The impact may be particularly drastic for patients for whom EU law protects the right to treatment. At a particular risk are patients with rare, 'orphan', diseases whose treatments are uniquely enabled at the EU level. We examine the potential effects of Brexit on the orphan sector and identify an opportunity to solve long-standing and intensifying difficulties, especially the pricing of orphan drugs.
