(5) Neonatal alloimmune thrombocytopenia (NAIT) is caused by platelet antigen incompatibility between the mother and fetus.
(6) Neonatal alloimmune thrombocytopenia (NAIT) occurs when maternal alloantibodies to antigens present on fetal platelets cause their immune destruction resulting in thrombocytopenia in the newborn infant or fetus.

(18) NAIT is mainly due to alloimmunization; the frequency varying among ethnic groups.
(19) Immunization against these alloantigens is implicated in NAIT and poly-transfused patients.
(20) In the serum of a mother who gave birth to a child with the typical clinical picture of NAIT we found an antibody directed against the new platelet antigen Sra.
