Genes that determine immunology and inflammation modify the basic defect of impaired ion conductance in cystic fibrosis epithelia.

ABSTRACT: BACKGROUND: The cystic fibrosis (CF) basic defect, caused by dysfunction of the apical chloride channel CFTR in the gastrointestinal and respiratory tract epithelia, has not been employed so far to support the role of CF modifier genes. METHODS: Patients were selected from 101 families with a total of 171 F508del-CFTR homozygous CF patients to identify CF modifying genes. A candidate gene based association study of 52 genes on 16 different chromosomes with a total of 182 genetic markers was performed. Differences in haplotype and/or diplotype distribution between case and reference CF subpopulations were analysed. RESULTS: Variants at immunologically relevant genes were associated with the manifestation of the CF basic defect (0.01
