A bad CFRT gene causing cystic fibrosis causes the body’s cells to contain the wrong amount of salt or water within the body. This causes the body to loose nutrients through sweat. There are more than 1,000 different types of mutations in the CFTR genes in people with cystic fibrosis. IF the screening test finds cystic fibrosis this does not always mean that
