The utility of empirically assigning ancestry groups in cross-population genetic studies of addiction.

CONCLUSIONS: We were able to create more genetically homogenous groups and reduce sample and marker loss through cross-ancestry meta-analysis, potentially increasing power to detect etiologically relevant variation. Our approach provides a framework for empirically assigning genetic ancestry groups which can be applied to other ethnically diverse genetic studies. SCIENTIFIC SIGNIFICANCE: Given the important public health impact and demonstrable gains in statistical power from studying diverse populations, empirically sound practices for genetic studies are needed.
