Essential Medical Genetics gives a balanced introduction to the basic principles of genetics and how it is applied to the understanding and treatment of diseases with a genetic component. Divided into three sections, basic principles, common situations in clinical genetics, and electronic databases, it covers all the information that medical students are taught at both preclinical and clinical level. The third section on electronic databases assists students on how to get the most out of these as they become more and more fundamental to undergraduate courses on genetics.
