How Genetic Diseases Are Transferred?

Genetic illnesses are passed down from parents to their children through mutated and dysfunctional genes. Children diagnosed with genetic diseases may have inherited the abnormal, dysfunctional or mutated gene from either one, or both of their parents. Genetic diseases can be passed down through generations even if the carrier doesnt have any symptoms of carrying that disease. The risk of getting a genetic disease increases if both parents carry abnormal or dysfunctional genes. A couple of the most prevalent diseases that are passed through generations are Tay-Sachs disease and cystic fibrosis. Such illnesses as depression and even alcoholism can become more common in children if another family member has experienced the same illnesses.

Contagious or Not? The majority of genetic diseases occur at birth. You cannot catch the disease from someone else who has the disease. You are either born with the genetic disease in your DNA or not. So the disease can be inherited from your parents through the DNA, but you cannot catch the disease from someone who has it. No person with a genetic disease is contagious or infectious to the people around them.
