人类基因遗传病是由于人类的遗传物质一基因发生突变而导致的机体结构和功能异常的疾病。人类基因遗传病可分为单基因遗传病和多基因遗传病两大类。据统计,到1981年为止,单基因遗传病已发现有3,303种,再加上多基因遗传病的病种,那总数相当惊人!因此从事人类基因遗传病的研究,日益受到人们极大的重视。基因的本质染色体是遗传物质的载体。人体23对染色
Human genetic disease is due to the genetic material of human genetic mutation caused by the body structure and function of the disease. Human genetic disease can be divided into single gene disease and polygenic disease two categories. According to statistics, up until 1981, 3,303 single-gene genetic diseases have been found, and together with the multi-gene genetic diseases, the total number is quite alarming! Therefore, the research on the genetic diseases of human genes is receiving more and more attention . The essential chromosome of a gene is a vector of genetic material. Human body 23 pairs
