ABO-HDN is a common disease of newborn in China and currently there is no satisfactory method to predict it in the antepartum period. It has been reported that Fc(gamma)RIIa (CD32) genotype is associated with both infectious diseases induced by bacteria and parasitemia. There is a relationship between IgG subclass and RH-HDN. To study the pathogenesis of ABO-HDN and to find reliable method to diagnose ABO-HDN, we investigated the polymorphism of Fc(gamma)RIIa (CD32) and distribution of IgG subclass in infants with ABO-HDN and their mothers by polymerase chain reaction or ELISA assay. We observed that the frequency of HH131 genotype is lower in infants with ABO-HDN than in controls (p < 0.01), while the frequency of HR131 genotype is higher in ABO-HDN infants than that in controls (p < 0.01). The genotype HR131 and concentrations of IgG1 and IgG3 are significantly correlated with ABO-HDN. Our results demonstrated, for the first time, that there is a correlation between ABO-HDN and CD32, and different IgG subclass distribution. Our study may contribute to the development of an early diagnostic method for HDN.
