What is prenatal genetics?

Prenatal genetics is the study of genetic factors that can affect the unborn child, usually by considering the child's family background and perform tests for the mother and the child. These tests may include non -invasive procedures such as ultrasound imaging, more complex tests that may require blood samples from a woman who is pregnant or considers pregnancy, and even genetic testing of the unborn child still in the uterus. There are a number of congenital diseases and other health conditions that can be identified through this type of testing. Prenatal genetics can be a somewhat controversial field due to the potential for abuse that such testing and information could create.

Sometimes called prenatal screening, a study of prenatal genetics can be useful in identifying risk factors for a wide range of congenital defects and endless disorders. Most of this research cannot be used directly to change chances to defects or disorders that are formed through geneticManipules, but are usually used to educate and prepare future parents for challenges they can face. Parents or potential parents are performed a large number of testing associated with prenatal genetics to determine any genetic predisposition that may have or their descendants for certain diseases.

This often includes information about the family history of every parent called their "pedigree". Prenatal genetic research for a couple may include basic medical history and blood tests to learn more about their genetic make -up. Once a woman is pregnant, there are other types of tests that can also be performed to contain the information set directly from the fetus. This may include ultrasonic scanning that shows the child's physical appearance, as well as drawing amniotic fluid for testing, although it can be potentially dangerous to the child.

Information obtained by the TprotalHerough genetics can be used to identify possible risks of a wide range of diseases and disorders. This may include congenital defects or disabilities with which the child can be born and basic health information. The parents of the unborn child may be informed of the possible health risks they should be aware of in the education of their child. This belongs to everything from higher risks of heart disease or cancer to an increased probability of an asthmatic or autistic child.

However, the collection of information on prenatal genetics is a controversial subject, but because of the nature of this information. In some individuals, there is fear that such information can be used to end pregnancy due to the increased health risks of the child, regardless of real illness. The subject of prenatal genetics was also interesting for sci -fi writers in terms of the potential for genetic manipulation and engineering of “more perfect” children during fertilization.
