title: [Incidence of cystic fibrosis in Brittany (author's transl)].
abstract: Incidence of cystic fibrosis has been estimated in three adjacent geographic areas of Brittany: North Finistere, South Finistere and Morbihan. This incidence is respectively 6.0 x 10(-4), 4.8 x 10(-4), 2.9 x 10(-4) in these three areas. A significant difference between North Finistere and Morbihan was found. Without proofs in favor of natural selection, genetic drift seems to be a possible explanation of this variation. Moreover, as in other studies, a genetic heterogeneity of the disease was not shown.
