[Distribution of HLA antigens among the population of Finistère (France) (author's transl)].

We have studied by using HLA system, 200 people, without filiation but having the same geographic origine (Finistère). The results have been compared with those measured for Parisian and Basque population. A significantly decrease of antigen A29, B18 and BW16 frequency have been observed in the population from Finistere. But, antigen B8 and B27 seems to be more frequent than in population from Paris. A linkage desequilibrium is described for A1-B8 and A3-B7 haplotypes as in population from Paris, but the desequilibrium for A11-B5 seens to be characteristic of population from Finistere.
