title: The FcgammaRIIa polymorphism in patients with chronic kidney graft rejection.
abstract: The FcgammaRIIa receptors, which provide a crucial link between cellular and humoral components of the immune response, display allelic polymorphism. Individuals are homozygous for either arginine 131 (RR131) or histidine 131 (HH131) or are heterozygous for these two alleles (RH131). The HH131 genotype binds human IgG2 with high RR131 with low, and RH131 with intermediate affinity. The aim of the study was to evaluate the FcgammaRIIa polymorphism in patients with chronic kidney graft rejection. The study included 121 renal transplant recipients: 53 patients with long-term stable graft function and 68 with chronic allograft rejection. The distribution of FcgammaRIIa genotypes in patients with chronic kidney graft rejection did not differ significantly from that in patients with stable graft function. The results suggest that the FcgammaRIIa polymorphism is not an important genetic risk factor for chronic rejection of kidney allografts.
