Popis: BackgroundLittle is known about the relationship between cystic fibrosis transmembrane conductance regulator (CFTR) gene mutations in Asian patients and severe asthma or idiopathic bronchiectasis. We investigated this potential relationship in the Singaporean Chinese.MethodsTwenty patients with chronic pulmonary disease, 14 with severe asthma and 6 with idiopathic bronchiectasis, were screened for CFTR mutations by direct gene sequencing. The frequencies of identified putative mutations were compared against 40 unaffected controls and 96 unselected population samples.ResultsThree missense mutations (I125T, I556V, and Q1352H) and 1 splice site variant (intron 8 12TG5T) were identified in a total of 10 patients, representing a combined mutant/variant allele frequency of 0.25. These alleles were also observed in the controls, but at a significantly lower allele frequency of 0.09 (P
