Fetal and neonatal alloimmune thrombocytopenia (FNAIT) risk across racial and ethnic populations: interim data from an international, prospective natural history study
Objective Fetal and neonatal alloimmune thrombocytopenia (FNAIT) is a rare disease that can result in severe bleeding in a fetus or newborn, including intracranial hemorrhage. Maternal-fetal human platelet antigen (HPA)-1a incompatibility is a prerequisite to maternal HPA-1a alloimmunization, which may result in FNAIT. The risk of HPA-1a alloimmunization is approximately 25-times higher in HPA-1
