With only 12 known patients in Germany SSADH-deficiency is ultra rare. No one understands the disease, no one researches it, no one develops therapies. That was 3 years ago. Our association this year has published a review paper with scientific partners, carried out the first roundtable for clinicians and researchers and has now handed in the first application to an EU research call: The European joint programme on rare diseases. We´d like to reaffirm every rare disease group: be ultra active – you can achieve anything – but most importantly you can give hope to your patients!
