title: Biochemical HLA typing: a population study in 112 Caucasians.
abstract: In order to define frequencies and associations of biochemically defined HLA-A and -B specificities and their variants and subtypes in a Caucasian population, biochemical HLA typing was performed in a panel of 112 Austrians. Already known rare variants of HLA-A2, A3, A30, Aw33 and B39 and the more frequent subtypes of HLA-B27, B35, B44 and, in addition, a so far unknown variant of HLA-B18 were present in the panel. Family segregation analyses of the biochemically defined HLA class I variants revealed that they could be found only in certain rare haplotypes, most of them in high linkage disequilibrium. The basic variant of HLA-A30, for example, obviously occurred only in the HLA-A30, B49, Cw7 haplotype, similar to the Aw33 acidic variant, which was exclusively found in the Aw33, Bw58, Cw3 haplotype. None of the biochemical variants was found in frequent common haplotypes.
