1. What is Genetic Testing?
It’s based on the theory that the 23 pairs of chromosomes that you inherit from your parents influence more than just the way you look – these chromosomes define your health and what your body’s future will look like.
The study of a person’s DNA to identify existing mutations or changes in the genes is called genetic testing. The tests help decode and understand our DNA composition as an individual.
Genetic tests can confirm or rule out a suspected genetic condition or help determine a person’s chance of developing or passing on a genetic disorder.
In 2013, American actor Angelina Jolie made headlines after she underwent preventive surgeries to remove her breasts, uterus and fallopian tubes after a test showed she had the BRCA1 gene. The gene indicated that she had an 87 percent risk of contracting breast cancer and a 50 percent risk of getting ovarian cancer in the future.
