hereditary disease based on mutations, ie changes in the hereditary characteristics of an organism that occur as a result of restructuring in the structures responsible for the transmission and storage of genetic information.The most popular diseases of this type which are compatible with life, considered phenylketonuria, hemophilia, and Down syndrome.
Down syndrome is a chromosomal disorder, occurring once in the 700-800 cases.For the first time a disease has been recorded in the distant 1866, but only in 1959 was proved its relation with abnormal chromosome.Under the influence of still unexplained reasons during the maturation of the egg in the twenty-first pair of chromosomes instead of two, there are three chromosomes.In addition to physical abnormalities for people suffering from Down's syndrome, innate characteristic of dementia.The higher the age of the woman, the higher the probability of a child affected with the disease.Statistics eloquent - in 19-year-old girl once such cases are 1,600 cases, while for the 39-year-old women, the figure is 80.
