A new platelet alloantigen, Swi^a, located on glycoprotein Ia identified in a family with fetal and neonatal alloimmune thrombocytopenia

Abstract

In this study we defined a new PLT alloantigen Swi(a) that was involved in a case of additional immunization against HPA-1a. Our observations demonstrate that combinations of PLT-specific alloantibodies may comprise low-frequency alloantigens.
