Certain genetic factors may play a role in increasing the risk of obstructive sleep apnea (OSA). A person who has a close relative with OSA is more likely to have it as well.

When you compare the genetic code of two people, it is 99.9% identical. So why are we so different? Because our DNA is made up of an astronomical number of molecules, the 0.1% of genes that are distinct is enough to explain these differences!

Changes may affect some of the cells in your body, but on the whole your DNA does not change during your lifetime. This means that the results of a genetic test done at age seven will be the same if you do it again at age 90!
