What is the genetic disorder of cystic fibrosis and what are the symptoms?

Cystic fibrosis is a disease that is inherited by children
from their parents. For a person to have cystic fibrosis, two copies of the cystic
fibrosis gene have to be inherited, one from each
parent.

Cystic fibrosis leads to the accumulation of mucus
in vital organs like the lungs, the pancreas and the digestive system. This leads to the
lungs getting inflamed which does not allow the patient to breathe normally. The
collection of mucus in the pancreas and the digestive system does not allow normal
production and distribution of enzymes which inhibits digestion. To manage the effects
of cystic fibrosis, patients have to take synthetic enzymes with their
food.

Some symptoms of cystic fibrosis are frequent lung
infections, difficulty in breathing, a salty tasting skin, poor growth and difficulty in
bowel movements.
