Abstract

HLA, complement, and glyoxalase I alleles were studied in 29 families in which at least one member has classical 21-hydroxylase-deficiency congenital adrenal hyperplasia. A rare complement allele, C4B*31, was found in over 20% of the haplotypes defined in these families and was always part of the complement haplotype BF*F, C2*C, C4A*QO, C4B*31 (abbreviated FCO,31). The haplotype containing this rare set of complement alleles always carried the rare HLA allele, HLA-Bw47, usually carried HLA-A3, and almost always had the alleles HLA-Cw6, HLA-DR7, and the glyoxalase I (GLO) allele GLO1. Thus over 20% of the haplotypes in the population studied contained all or almost all of the rare extended haplotype HLA-(A3), Bw47, Cw6,DR7, FCO,31, GLO 1. 3 other haplotypes were each found twice in unrelated patients concordant for their disease phenotype and ethnic background. Extended MHC haplotypes may be markers for different genetic mutations causing 21-hydroxylase deficiency.
