RESUMO
Antigen, gene and haplotype frequencies are imnportant data for population analysis, poaternity exclusion testing, genetic studies, and for organ transplantation selection. We have studied the class I histocompatibility antigens of 617 unrelated individuals from the city of Säo Paulo, Brazil, to determine antigen and gene frequencies of HLA-A and 28 HLA-B antigens. Estimated haplotype frequencies were also determined, as well as the genetic distances of this population from European Caucasian and Negro populations. A previously unknown linkage disequilibrium was detected for A23-B49 and a clear trend towards antigen frequencies intermediate between Caucasoid and Negro populations was observed
