In modern times, future parents, planningpregnancy, often pay close attention to the sign of the zodiac their future child or of what sex, completely forgetting that it is necessary first of all to pass the necessary tests and get a consultation from a geneticist.
Genetics is the science of heredity,thanks to which doctors created special genetic tests aimed at identifying genes that can be the cause of congenital diseases transmitted by inheritance. Thus, genetics in pregnancy, makes it possible to conduct research on various diseases transmitted by inheritance, both before conception and during pregnancy.
To date, a large number of familiesseek advice from geneticists about all sorts of diseases. Undoubtedly, the consultation of a geneticist in pregnancy is necessary, first of all, to determine a possible risk group for the presence of diseases that can be transmitted by inheritance. The genetic doctor will carry out all the necessary studies to identify the future child's genetic pathology.
Thus, when planning a pregnancy, aalso in the presence of pregnancy, gynecologists are advised to undergo a medical-genetic prenatal study. This study is divided into three main groups:
- invasive examination with surgical intervention, due to which tissue and fetal cells are obtained;
- non-invasive research, that is, research without surgical intervention, which includes ultrasound and doplerography of blood vessels and the placenta.
- screening method of diagnosis, which consists in determining in the mother's blood substances that can tell about the congenital defects of the fetus.
We can say that genetics in pregnancyAlso includes the definition of groups of genetic risk, which includes people with a high probability of having children with hereditary diseases. These risk groups include:
- women who have repeated miscarriages or frozen pregnancies;
- women who used during the conception of drugs that have a teratogenic composition;
- women over thirty-five and men who are over forty years of age;
- parents who have various diseases that are inherited;
- Parents who are married in marriage;
- parents who have experienced exposure to radiation or chemicals.
When a pregnancy occurs, the gynecologist sendswoman on the passage of ultrasound. The first ultrasound examinations take place at the time of pregnancy in five weeks, but the second one must be completed no later than fourteen weeks of pregnancy. This is connected with the fact that a woman during a woman's pregnancy has the opportunity at this time to diagnose the development of fetal malformations and determine some of its changes, which can be a pathology of chromosomes. In this case, the specialist will use the diagnostic method, like biopsy and amniocentesis. It is also recommended to undergo a third ultrasound at a period of twenty-two weeks of pregnancy to detect abnormalities in the development of the face, extremities and internal organs of the child. In this case, genetics in pregnancy allows you to treat a child in the womb or develop a treatment tactic after his birth until he is fully recovered.
It should be remembered that only a complexa geneticist's study of the pedigree, anamnesis of the woman and the state of health of both parents, makes it possible to use the appropriate survey tactics of the pregnant woman and choose the appropriate methods of treatment if necessary. In this way, genetics in pregnancy can prevent the birth of children with various abnormalities.
