Genetic testing is to see if you have a genetic disorder.
Pros of Gene Testing
If a couple has plans to start a family they can get tested to see if they inherited a gene that would make their children have the disease or have the chance of passing it on to their family.
If a parent has already had one child with a severe birth defect, sometimes it is caused by exposure to a toxin at an early age but other times not. It’s always good to be safe rather than sorry.
If a woman has had two or more miscarriages, this may mean that they have a severe chromosomal problem.
If a prenatal screening has an abnormal result doctors recommend gene testing.
If a child has genetic problems genetic testing could identify it and see if it’s genetic and find a diagnosis.
It can help identify treatments for a genetic disorder.
Cons of Gene Testing
Genetic tests can identify a particular problem gene, but can't always predict how severely that gene will affect the person who carries it. In cystic fibrosis, for example, finding a problem gene on chromosome number 7 can't necessarily predict whether a child will have serious lung problems or milder respiratory symptoms.
Also, simply having problem genes is only half the story because many illnesses develop from a mix of high-risk genes and environmental factors.
Genes are being identified that put people at risk for illnesses like cancer, heart disease, psychiatric disorders, and many other medical problems.
Severe complications have occurred in some patients receiving gene therapy, so current research with gene therapy is very carefully controlled.
- A total of 35 articles and 30 studies were conducted on Genetic Testing and the majority of the studies reported negative effects on carriers.
- Not all diseases can be found by using gene testing.
