第1章 绪论（The first chapter is introduction） The first chapter is introduction Medical genetics is a comprehensive subject which applies the theories and methods of genetics to study the genetic problems of human genetic diseases and human diseases. The mechanism, which studies of genetic disease transmission, epidemiology, diagnosis, treatment, prognosis and prevention of problems, provide a theoretical basis for the control of genetic diseases and its prevalence in the population, and provide the methods and measures of genetic disease diagnosis, treatment and prevention, to improve human health, to improve the quality of the population contribution. The field of medical genetics involves the fields of basic medicine and clinical medicine. Therefore, medical genetics is not only an important basic medicine course, but also a bridge course between preclinical medicine and clinical medicine. With the development of medical science, scientists have recognized some of the problems encountered in the practice of Medicine (such as etiology, pathogenesis, diagnosis of some diseases prevention and treatment etc.), especially in some complex and refractory diseases need to use the theory and method of genetics can be solved. The direct relationship between medical genetics and clinical medicine and other medical science makes it necessary for modern doctors to understand this field. This chapter first introduces the subject of medical genetics, nature, task and role in medical education and the definition, characteristics and classification of genetic disease and genetic factors in disease development and the therapeutic effect; then based on the history of medical genetics, understand the process of development of each branch of the subject in the achievements and contributions to the development of medicine; finally understand single gene disease, genetic diseases and research methods of chromosome diseases and countermeasures. I. basic outline 1. grasp the concepts of med
