Most genetic disorders are present from birth and are quite rare, often affecting only one person in every several thousand or million.
While some of these genetic diseases are well known, such as sickle cell anemia and cystic fibrosis, others are so rare that there is only one affected person in the world. Whether a genetic disease affects thousands or just one person, there are many challenges for patients, their families, and caregivers, including the time it takes for many patients to get a correct diagnosis.
Our focus is on the discovery of new genetic disorders and improving our understanding of those we already know. Using zebrafish, mouse models, patient cells and stem cell technologies, we are probing the pathological mechanisms of genetic disorders to address unanswered questions. Our fundamental research has led to clinically useful diagnostic tests and novel therapies for patients. Strong patient and advocacy relations serve as a foundation for our goal to shed light on the obscure paths of genetic disorders and provide solid information and guidance.
