title: Analysis of gene-gene interactions.
abstract: The goal of this unit is to introduce gene-gene interactions or epistasis as a significant complicating factor in the search for disease susceptibility genes. This unit begins with an overview of gene-gene interactions and why they are likely to be common; then, it reviews several statistical and computational methods for detecting and characterizing genes whose effects are dependent on other genes. The focus of this unit is genetic association studies of discrete and quantitative traits since most of the methods for detecting gene-gene interactions have been developed specifically for these study designs.
