## Abstract With the advent of rapid and relatively cheap genotyping technologies there is now the opportunity to attempt to identify geneβenvironment and geneβgene interactions when the number of genes and environmental factors is potentially large. Unfortunately the dimensionality of the paramete

β¦ Synopsis
This paper summarizes the contributions of group 8 to the Genetic Analysis Workshop 15. Group 8 focused on ways to address the possibility that genetic and environmental effects on phenotype may not be independent, but instead may interact in ways that could play important roles in determining phenotype. Among the eight contributors to this group, all three data sets (expression data, rheumatoid arthritis data, and simulated data) were analyzed. Contributions to this section fell into the two broad categories of refining the data (e.g. stratifying or weighting based on a covariate value) and explicitly modeling the interactions. The contributions also illustrate that there are at least two possible goals for such studies. One goal is simply to identify factors contributing to phenotype in the presence of interactions that might mask the signal to univariate methods. A related but distinct goal is to characterize an interaction (e.g. to determine if the interaction is significant).

The scientific and public health implications of gene-environment interaction warrant that the most powerful study designs and methods of analysis be used. Because traditional case-control designs, which use nonrelated subjects, have demonstrated the need for large samples to detect interactions, al
This paper illustrates how epidemiologic principles can be used to investigate relationships between genetic susceptibility and other risk factors for disease. Five plausible models are described for relationships between genetic and environmental effects, and an example of a simple mendelian disord
We assessed the sample size required for detecting gene-environment (G Γ E) interactions in a case-control study of complex diseases. The results suggest that large numbers of cases and controls will be required to detect G Γ E interaction for some odds ratio and exposure frequency combinations. The
