“The purpose is to provide an up-to-date, comprehensive resource for physicians and nurses who have an interest in learning more about immunodeficiencies. … This book’s approach is well organized, up to date, and easy to follow. … I highly recommend this book as a current and comprehensive resource, which also has great clinical relevance for medical students, residents and fellows, and general providers, as well as subspecialists including immunologists.” (Joseph R. Hageman, Doody's Book Reviews, July, 2017)“This updated text reviews in detail in 10 chapters the recent advances in this field. Clearly written, the authors review the clinical history, genetic diagnosis of the different entities and their management. For all pediatricians, geneticists and immunologists.” (Zvi Laron, Pediatric Endocrinology Reviews (PER), Vol. 14 (4), June, 2017)
