Phenotype-driven approaches have the advantage of making no assumptions about the function of genes and their products and have been successfully applied to the discovery of novel gene-phenotype relationships in many physiological systems. ENU mutagenesis of mice is used in many large-scale and more focused projects to generate and identify novel mouse models for the study of gene functions and human disease. This review examines the strategies and tools used in ENU mutagenesis screens to efficiently generate and identify functional mutations.Keywords: ankyrin; ethylnitrosourea; gene product; mutagenic agent; nucleic acid; thrombopoietin; thrombopoietin receptor; amino acid substitution; cancer research; carcinogenesis; chronic inflammation; DNA adduct; DNA polymorphism; enteritis; familial adenomatous Inflammatory bowel disease; Mouse models; N-ethyl-N-nitrosourea; Phenotype-driven201110.1152/ajpgi.00343.20102016-02-24
