Genetic Testing

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.
