New registry aims to unlock secrets of rare childhood blood-clotting disorder

This study is creating a registry to collect information from children diagnosed with antiphospholipid syndrome (APS), a condition that causes abnormal blood clots. Researchers aim to better understand what causes APS and how it is treated, with a focus on long-term survival. The study will enroll up to 50 participants who were 18 or younger at disease onset and meet specific lab criteria.
