g3?S population in which the conditions usually occur, a brief description of the phenotypes, and references. This appendix should serve as a valuable reference source for hematologists, geneticists, and other physicians and nurses who care for patients with hemoglobin disorders. Therefore, this book should be valuable to a wide range of readers. Clinicians and scientists will benefit from this remarkably current description of human hemoglobin and hemoglobinopathies. Those who wish to become familiar with the techniques and concepts of human molecular genetics (which also are applicable to other human conditions) and those who would like a handy reference text for the myriad of human globin mutations will appreciate this book.

Human Hemoglobin Genetics, by George R. Honig and Junius G. Adams III, 452 pp, with illus, $59, New York, Springer-Verlag, 1986

The human hemoglobin system is unique in the degree of information that exists about the globin genes and their regulation, the amino acid sequences of the gene products, and the influence that individual amino acids exert on the function of the hemoglobin molecule. In addition, hundreds of mutations have been characterized. For many of these mutations, as for sickle /3-globin, the clinical phenotype is understood in terms of the effects of the molecular changes. This superb book describes this fascinating system, beginning with the form and function of hemoglobin, going back to the level of the gene and its mutations, and then proceeding forward again to the altered molecules Virginia V. Michels, M.D. that result in human diseases. Department of Medical Genetics The introduction includes an overview and a historical foundation that may be difficult to understand for the reader who is not conversant in molecular genetics. Lest this first chapter discourage readers from continuing, some may wish Goldberg's Genetic and Metabolic Eye Disease, 2nd ed, edited by William Andrew Renie, to go directly to chapter 2, "The Human Hemo574 pp, with illus, $85, Boston, Little, Brown globins."
