{ "Genetic Studies of Chronic Active Epstein-Barr Disease", "This observational study is looking for genetic changes that cause Chronic Active Epstein-Barr Virus (CAEBV), a rare and serious disease, mostly in children and young adults. Researchers will study blood and tissue samples from up to 50 patients with CAEBV and up to 150 of their family members. The main goal is to find the specific genetic mutations responsible for CAEBV. This study also aims to learn more about how CAEBV progresses over time. The study is currently ongoing and is open to individuals aged 1 to 120 years old who have CAEBV or are relatives of someone with CAEBV.", "design": "This is an observational study planning to enroll up to 300 participants, including patients with CAEBV and their relatives. It is not a treatment study but focuses on understanding the disease.", "commitments": "Participants will provide blood and/or tissue samples. Some patients may also be invited for evaluations at the NIH Clinical Center, where medically necessary studies of disease progression will be performed.", "compensation": "Not stated in the trial record.", "follow_up": "The primary goal of identifying genetic mutations is measured on an ongoing basis, suggesting continuous study of samples.", }
