Human MHC class III (Bf, C2, C4) genes and GLO: their association with other HLA antigens and extended haplotypes in the Spanish population.

C4 allotype frequencies and their combination with factor B and C2 alleles (complotypes) were studied in a sample of the Spanish population in relation to MHC class I, class II and GLO alleles. The shorter genetic distances found for C4 between Spaniards and North Africans and the high frequency of extended HLA haplotypes (GLO 2) HLA-DR3 F1C30 HLA-B18 HLA… (More)
