title: Anti-HPA-4b (anti-Yuk(a)) neonatal alloimmune thrombocytopenia: first report in a Caucasian family.
abstract: Neonatal alloimmune thrombocytopenia (NAIT) is caused by platelet antigen incompatibility between the mother and fetus. NAIT is mainly due to alloimmunization; the frequency varying among ethnic groups. In Caucasians HPA-1a is the antigen most frequently implicated. In Japan, NAIT due to anti-HPA-4b antibody has already been described, but this is the first case to be reported in Caucasians.
