title: Detection of CFTR gene mutations in patients suffering from chronic bronchitis.
abstract: BACKGROUND
  The purpose of the study was to examine cystic fibrosis transmembrane conductance regulator (CFTR) gene mutations in patients suffering from chronic bronchitis.
  
  
  METHODS
  Thirty-two patients admitted to the Department of Pulmonology, Lublin School of Medicine, Lublin, Poland between 1995 and 1996 due to chronic bronchitis were included in the study. Patients were analyzed for the eight most common mutations of the CFTR gene (DeltaF508, G542X, N1303K, 1717-1(GoA)), W1282X, G551D, R553X, and DeltaI507 by the reverse-hybridization method.
  
  
  RESULTS
  CFTR gene mutations were found in five of 32 (16%) patients, all within the DeltaF508 region of the CFTR gene. All positive samples were obtained from patients heterozygous for the DeltaF508 mutation. The presence of the DeltaF508 mutation was considered statistically significant when our study group was compared to the study of Poland's general population (p <0.05 Fisher's exact test).
  
  
  CONCLUSIONS
  Our results suggest there is an increased presence of the DeltaF508 point mutation of the CFTR gene in Polish patients suffering from chronic bronchitis.
