Planning for pregnancy goes through several stages. Future mothers and fathers should prepare their bodies for conception, undergo examinations, and be tested. Genetic consultation before pregnancy will not be redundant.
Baby gets 23 chromosomes from mom and dad. In order for a child to have any genetic abnormalities, a single sex cell with the wrong set of chromosomes is enough. The abnormal structure of chromosomes in the germ cells may appear if the future parents drank alcohol, smoked, took medicines during the maturation of sperm and eggs. To avoid this, three months before conception should lead a healthy lifestyle. But this is not the only cause of developmental disabilities. Only a doctor can identify a potential threat. Therefore, future parents need genetic counseling when planning a pregnancy.

HOW A CONSULTATION TAKES PLACE IN GENETICS
To determine the possible deviations in the child at the planning stage of pregnancy, the doctor needs to know the history of diseases of future parents.Geneticist will ask about all sorts of diseases and deviations of relatives. Also, in order to compile a complete picture, he will need information about medicines that were taken by a man or a woman, living conditions, ecology, and features of the profession.
The doctor may give directions for testing. Genetic analysis in planning will help to more accurately determine the appearance of abnormalities in the fetus. Typically, such a survey includes biochemical blood tests, consultations of the therapist, endocrinologist, and neuropathologist. In some cases, future parents will need a study of chromosomes (cytogenetic analysis) and HLA-typing (for couples who have a suspicion of genetic incompatibility).

In some cases (hematogenic marriages, miscarriages, infertility) conduct a special genetic study called HLA-typing.
After the consultation, the geneticist makes a complete picture of health and determines whether there is a risk of deviations for the future baby. If the risk is less than 10% in prison, it means that the couple will give birth to a healthy baby.10-20% - a child can be born with violations. In this case, a woman during pregnancy needs to carefully monitor the development of the fetus - often see a doctor, do an ultrasound, and so on. At risk of more than 20%, a geneticist may advise you to give up pregnancy.
