What are genetic congenital defects?
understanding genetic congenital defects first means understanding the genetic term. There may be differences in the way this word is used. Sometimes genetic means due to the inheritance of one additional genes that lead to an expression of one or more symptoms or a change in the average function of the body. Another way to use this term is to express errors in the way chromosomes or genes that do not have hereditary distortion work; Such mistakes could occur from environment, disease, age or unknown factors, resulting in a form of genetic congenital defects that are not inherited. Each parent can have to carry a defect gene to express genetically. In these cases, there are only defects if the child inherits the recessive gene from every parent, which will not always happen. In other cases, one gene is inherited at any time, there is a congenital defect called autosomal dominant. Running always noted the body's malformation and some people do not show an importantcaries about genetic congenital defects when they are born. Instead, the defects will be reflected later.
There are many examples of genetic congenital defects that can be very serious. These include Tay-Sachs' disease, which causes gradual deterioration and has an extremely high mortality. It can be said that this is related to the gene, because people do or wear this gene, and when two parents are carriers, they have one in four risk of having a child with this disease. It is a recessive disease, but people who do not get illness can become a gene wearers and should undergo genetic testing before children. Other inherited diseases include anemia of sickle cells, cystic fibrosis, muscle dystrophy and Marfan syndrome; There are many other examples.
errors in genes can cause the second type of genetic birth. One or more genes can work as they should, whether through PRsharply or because of some nature accident. This is the case of heart defects, although there are several rare conditions of heart defects, such as heterotaxia that are inherited. Most occur for unknown reasons, but these reasons clearly include genes that cannot order the work of the body properly.
It should also be noted that this second type of defect can be hereditary. Just because the pattern of the inheritance was not established does not mean that it is not there. It means only medical scientists who have not uncovered it.
Another defect that is relatively common and can be hereditary or inherited is the cleft floor. Sometimes doctors do not necessarily have to be sure what creates a problem. Other conditions could result from the environmental factors of the change in the way the genes are expressed.
Například Syndrom Downa může být zděděn a je častější v rodinách s Downem KIDS. The risk of a child on the condition also increases with age because female eggs or eggs are aging. Down syndrome rises for women over 35 years, regardless of whether people have a family history.
Lack of certain things, such as folic acid supplements before and during pregnancy, can create defects of the spine nerve tube, and there is evidence that genes that build the heart of the disease, most illegal drugs and alcohol can also cause defective gene expression, resulting in various defects that are not inherited.
Many people who have a child with congenital defects do not expect and have no family history of defects. In a sense, this facilitates hereditary or genetic congenital defects soon captured early, due to the approach to genetic counseling. Knowledge of family history is a good way to find out whether working with a genetic advisor would be suitable before trying to become pregnant. Yet, even with Clear family history, gene failure sometimes works correctly, that the risk is always present, although most defects are fortunately rare.
