Cystic fibrosis is a progressive, genetic disorder that affects lungs and digestive system. The disease is characterized by build up of thick sticky mucus in the lungs, pancreas and other organs. The patients experience difficulty breathing.
Lungs and digestive system are affected by this disease.
Cystic fibrosis is caused due to mutation in the gene that makes a protein, CFTR (cystic fibrosis transmembrane regulator). The cells become unable to move salt and water effectively making the mucus thick instead of thin & watery.
Yes, it is a genetic/inherited disorder.
