Title: Costs and benefits of environmental data in investigations of gene-disease associations (Slides)

Abstract: Concomitant collection of environmental data can help identify gene-disease associations. However, it is typically costly to obtain exposure data, and this cost could instead be applied to measure disease status and genotype on more subjects. Thus, from a fixed resource perspective, the additional cost of exposure assessment may be so high that measuring only disease status and genotype for a large study sample may yield more power than measuring disease status, genotype, and environmental exposure for a smaller study sample.
