The authors examine whether the mutations and haplotypes of CFTR will increase the risk of developing idiopathic chronic pancreatitis (ICP) in Chinese and their genotype and phenotype correlations. Seventy-eight patients with ICP and 200 geographically and ethnically matched controls in Taiwan were analyzed. The entire 27 coding and intronic regions of the CFTR gene were identified using heteroduplex analytical techniques and confirmed by sequencing analysis. The presence of 125G/C, 1001+ 10C>T, IVSTn(TG)m, 1540A>G, c2694T>G, and c4521G>A were determined by directing sequencing. Abnormal CFTR allele was found to be thrice as frequent in ICP patients as in controls (22/156 vs 19/400, p < 0.0001). T5 allele was associated with early onset of ICP. In six-loci haplotype analysis, 13 common haplotypes were assembled in the 278 individuals tested. The 125G/1001+ 11C/TG12/470M/2694T/4521G haplotype was associated with risk of ICP (odds ratio 11.3; 95% confidence interval 2.3-54.6, p =0.008) in Chinese. The mutation spectrum is different from other ethnic groups. A population-specific panel of CFTR changes should be recommended for targeted populations including ICP in Chinese. It is important to design suitable screening programs for different populations. ? 2007 The Authors Journal compilation ? 2007 Blackwell Munksgaard. |
