title: Genes and geography.
abstract: The author discusses a number of genetically determined diseases, such as hemoglobinopathies, acute intermittent porphyria, familial Mediterranean fever and so-called acquired hypogammaglobulinemia from the geographical point of view. Possible factors explaining localized increases in incidence are discussed. The importance of isolates for the development of such foci is stressed.
