    Abstract

    Human IgG receptors (FcgammaR) display considerable heterogeneity, and are crucial immune response modulating molecules. FcgammaRIIA, FcgammaRIIIA, and FcgammaRIIIB display functional biallelic polymorphisms. FcgammaR polymorphisms have been found associated with susceptibility to infectious and autoimmune diseases. Linked transmission of FcgammaR alleles was studied by determining the distribution of FcgammaRIIA-FcgammaRIIIA-FcgammaRIIIB genotype combinations in 514 Dutch Caucasian, and 149 Japanese blood donors. The structure of the FcgammaR locus was studied by radiation hybrid mapping of FcgammaRIA, FcgammaRIIA, FcgammaRIIB, FcgammaRIIIA, FcgammaRIIIB, and adjacent genes from the pentraxin family. In addition, crossing-over frequencies within the FcgammaR locus were determined in 63 Dutch Caucasian families, encompassing 183 individuals. FcgammaRII and FcgammaRIII subclasses were mapped in close proximity (0.47-3.14 cR). Accordingly, crossing-over frequencies within the FcgammaRII-III locus in Dutch families were low. Analysis of combined FcgammaR genotypes strongly suggested non-random distribution of FcgammaRIIA-FcgammaRIIIA-, and FcgammaRIIIA-FcgammaRIIIB genotypes in Dutch donors (P
