Statistical Genetics

The methodological approaches of genetic epidemiology and statistical genetics are primarily focused on the identification of genetic variation underlying complex disease. Here at IBG, there is a particular interest in the genetics of psychiatric, behavioral and neurologic disorders. IBG researchers make use of well-characterized longitudinal data arising from both family-based and population-based samples. Statistical and epidemiological approaches being used at IBG include linkage analysis, genome-wide association, candidate gene association and the analysis of sequence data.

Studies:

All human studies utilize statistical genetics.
