Allergic diseases are complex diseases caused by a combination of genetic and environmental factors. To determine the genetic components of these diseases and to discover the genes and cellular pathways underlying them, a large number of genetic studies have been conducted. Progress in genetics enables us to conduct genome-wide association studies (GWASs), which is a comprehensive and unbiased approach to identify susceptibility loci for multifactorial diseases. Recent GWASs have convincingly detected a large number of loci associated with allergic diseases. Candidate genes in the susceptibility loci suggest roles for epithelial barrier functions, innate-adaptive immunity, IL-1 family signaling, regulatory T cells and the vitamin D pathway in the pathogenesis of allergic diseases. Interestingly, the IL1RL1, HLA, IL13 and C11orf30 regions are overlapping susceptibility loci among atopic dermatitis and asthma or allergic rhinitis. Although a more complete collection of associated genes and pathways is needed, biologic insights revealed by GWASs improve our understanding of the pathophysiology of human allergic diseases and contribute to the development of better treatment and preventive strategies.
