Distribution of HLA class II alleles among Norwegian Caucasians.

We report genomic HLA class II typing of 181 randomly selected Norwegian controls. Seventeen DRB1, 7 DQA1, 10 DQB1, 2 DPA1, and 16 DPB1 alleles were found in the tested population. HLA class II antigen and allele frequencies are given, as well as the distribution of DRB1, DQA1, DQB1 haplotypes. Linkage disequilibrium between some DPB1 alleles and DRB1 and/or DQB1 alleles are also reported.
