A classical case-control study is a powerful and cost-efficient approach to detect association of genetic markers with complex disease phenotypes. However, only a small fraction of significant association results has been replicated by other studies. Undetected genetic substructures in the population may be one of the reasons for spurious or biased results. The German "Genomic Control" study aims at detecting genetic differentiation between one Southern German population, represented by the KORA study (KORA Survey S4 (1999/2001)), and two Northern German populations (SHIP, Greifswald, and POPGEN, Schleswig-Holstein). Relevant population-substructures will be assessed, as well as their influence on case-control studies. Since KORA samples are used as controls for different German genetic association studies, the knowledge gained through this Genomic Control project will influence the planning of further genetic association studies. A second project, the European LD study, deals with the detection and comparison of linkage disequilibrium (LD) patterns in the human genome for eight distinct European populations. In general, a conservation of LD patterns across European samples can be observed for most gene regions. However, there are chromosomal regions with variable LD structure which may have implications on the fine-mapping of genes in different populations.
