Current Protocols in Human Genetics, edited by Nicholas C. Dracopoli and others, is a comprehensive collection of over 150 protocols covering nine chapters on genetic mapping, markers, somatic hybrids, cytogenetics, cloning, candidate gene identification, mutation searching, clinical cytogenetics, and molecular genetics. Each protocol includes supporting sections such as commentary, history, alternatives, troubleshooting, and references. The protocols are written by developers or experienced users and are easy to follow, even for inexperienced researchers. They are accompanied by discussions of "dos," "don'ts," advantages, and disadvantages. The book is well-organized and includes references to primary literature. However, it is not complete, as it is a companion to Current Protocols of Molecular Biology and lacks some basic techniques. It also only superficially discusses informatics. Despite these limitations, the book is an excellent research and teaching tool, with quarterly updates. It is available in both printed and CD-ROM formats. The book is also useful for studying other higher-eukaryotic genomes. Guidebook to the Homeobox Genes, edited by Denis Duboule, is an excellent introduction to homeobox genes and a fine reference for developmental biologists. It includes three introductory chapters followed by summaries of over 300 homeobox genes. The first chapter reviews the history of homeobox genes, while the second discusses their role in cell differentiation and evolution. The third chapter presents a comprehensive classification system for homeobox genes. The book provides detailed information on each gene, including alternative names, chromosomal location, and function. It is an authoritative, well-organized, and comprehensive overview of homeobox genes.Current Protocols in Human Genetics, edited by Nicholas C.
