Genetics of Complex Disease examines how the identification of genetic variations that increase or reduce the risk of common, genetically complex, diseases can be used to improve our understanding of the pathology of many common diseases; enable better patient management and care; and help with differential diagnosis. It starts with the questions of \"what\", \"why\" and \"how,\" and continues with more specific topics such as HLA and immunogenetics, pharmacogenetics, cancer, and diabetes. It finishes with a discussion of ethical issues, and looks to future developments. Genetics of Complex Disease is designed for advanced undergraduate and graduate students in the biomedical sciences and medicine. 4 Line drawings, color; 137 Line drawings, black and white
