Modern science has unlocked many of the mysteries of genetics, providing a blueprint for understanding the origins behind previously mysterious ailments and conditions, both common and uncommon. A complete understanding remains elusive, however: geneticists are still refining theories about what causes chromosomes to mutate, and genetic diseases remain difficult to diagnose and challenging to treat. This fascinating reference explores the scientific and human aspects of this complex field of science.

Encyclopedia of Human Genetics and Disease features nearly 400 entries, including well-known genetic diseases, rare and lesser-known genetic diseases, and the genetic factors that may contribute to common diseases and health conditions, such as breast cancer and obesity. The author presents in-depth discussions of concepts essential to understanding genetic disease in 18 entries that provide background on key topics, such as "Genetics 101," the genome and the foundations of genetics, genetic counseling, and newborn screening. Each of the 355 disorders profiled provides the history of the condition, its prevalence, causes, treatment (if any), and further reading. Interesting sidebars and compelling photos that help inform content accompany many entries.
