Report of two patients with associated conditions in addition to cystic fibrosis.

PURPOSE

To report two patients with associated conditions in addition to cystic fibrosis.

METHODS

We reviewed our database and report two patients with cystic fibrosis who had associated conditions. These patients also had novel disease causing CFTR mutations on full gene sequence analysis.

RESULTS

We identified 2 patients with novel disease causing cystic fibrosis transmembrane conductance regulator mutations that we report here. A 12-year-old female with cystic fibrosis, diagnosed at 18months, had normal pulmonary function tests and chest X-ray. Her main cystic fibrosis-related health issue was poor growth. Results of cystic fibrosis transmembrane conductance regulator DNA analysis showed deltaF508; L467P; and 7T/9T. She was later diagnosed with Crohn's disease. An 11-year-old male with Rubinstein-Taybi syndrome, diagnosed with cystic fibrosis at 2years of age, had minimal findings on chest X-ray and pancreatic insufficiency. Results of his cystic fibrosis transmembrane conductance regulator DNA analysis showed deltaF508; 4329delCT; and 7T/9T.

CONCLUSION

We report 2 patients with CF who had associated conditions and also had novel disease causing CFTR mutations. Associated conditions may worsen the clinical manifestations of CF and complicate medical management.
