Neonatal alloimmune thrombocytopenia caused by an antibody specific for a newly identified allele of human platelet antigen‐7

Abstract

We identified a new third allele of HPA-7, which is characterized by a 1297C>T mutation in the GPIIIa gene. This 1297C>T allele was found in 0.15% of the Japanese population. An antibody against this antigen could be the cause of severe NAIT.
