Cystic fibrosis is a genetic disorder caused by a defect in the CFTR gene on chromosome 7. This defect leads to the production of thick, sticky mucus in the lungs, which can cause coughing and difficulty breathing. Blood chromosome analysis would not be diagnostic for cystic fibrosis, but it may be ordered if there is concern about other chromosomal abnormalities.
