[HLA A, B, C and DR antigens in a urban population from Santiago of Chile].
HLA antigens vary in different ethnical groups and in Chile there are no reports on the frequency of these antigens in a normal representative population. The few existing studies are of indigenous populations and control groups, without including HLA-DR antigens. Therefore, the aim of this study was to study the frequency of HLA A, B and C antigens in 349 individuals and HLA-DR in 257, using the microlymphocytotoxicity method, and compared the results with those on normal caucasian populations (Europe and USA). Significant differences were found for 7 antigens of group A, 10 of group B, 4 of group C and 6 of group DR. The observed difference allow us to conclude that the population from Santiago has a distinct HLA antigen distribution. This fact must be bore in mind future studies in genetics, paternity or autoimmune diseases.
