Through the analysis of many genetic diseases, we concluded that genetic diseases and General diseases 5 main features.
1, hereditary
Patients carrying genes will continue by offspring a proliferation of genetic, population quality to bring harm should not be underestimated. Foreign reports have a classic example, in a Kac family in Kerala, on Martin\'s three generations of genetic quality are excellent and not found anything unusual. Later when in Martin and the children of a low energy married, born Martin, as well as its next four 482 143 per cent on behalf of low-energy, is the remaining 339 people, are also carriers of the faulty genes, but also continue to ease proliferation. Damading marriage with another intelligent woman in her normal epigenetic five-under 496, all normal, without low energy. Visible, has a strong hereditary genetic disease.
2, familial
19th century United Kingdom Queen Victoria of the family is a famous hemophilia families. The descendants of the Queen, in patients with hemophilia often found in its people, and adopted daughter carries genes and other Royal marriage, hemophilia passed on some European royal families, which appear a series of patients with hemophilia and hemophilia gene carriers. This is a disastrous tragedy for the family.
3, congenital
Most genetic diseases babies came to the world, already is a genetic disease of \"older patient\". Few genetic diseases children are normal at birth, but to a certain age when clinical symptoms occur. Congenital muscle tension, usually during puberty onset; Hereditary Chorea p symptoms will not open until at the age of 30-40. Although birth until many years after onset, but bane was had planted at the moment of sperm-egg binding. So has a congenital genetic disease.
4, lifelong
Most genetic diseases are difficult to cure, and has the characteristics of life. Although at present can take some measures, improve or prevent the onset of clinical symptoms in patients with certain genetic diseases, such as the broad bean diseases in patients with no touch of broad bean pollen, do not eat faba bean, are not taking such drugs, onset can be avoided. But not radical cure of disease genes, via harmful reproductive genes passed on to the next generation. Existing technology also cannot make a normal of abnormal chromosomes or genes, so harmful genes in patients with a life to exist.
5, high rates
Due to the development of medical science, infectious diseases, infectious diseases caused by environmental factors and gradually reduce the incidence of epidemics in the crowd, by contrast, the incidence of genetic diseases are rising. According to the report of the World Health Organization, Canada Montreal children\'s Hospital in 1969-1970 in children with the age of 18, and genetic diseases related to the relative incidence of up to 30%. According to statistics, the population of about one-third in people affected by genetic diseases are tired, and there is an increasing trend. Therefore, can no longer say genetic is a rare disorder, but important disease threat to human health, to adequate attention.
