ABSTRACT
<p><b>OBJECTIVE</b>To assess the association of vascular endothelial growth factor (VEGF) gene polymorphisms with susceptibility to Crohn's disease (CD) in a Chinese population.</p><p><b>METHODS</b>For 275 CD patients and 495 controls, the genotypes of VEGF gene rs699947 and rs3025039 loci were determined with a SNaPshot method.</p><p><b>RESULTS</b>The allelic and genotypic frequencies of the rs699947 and rs3025039 loci did not differ between the two groups (all P>0.05). By stratification analysis, allele A and genotype CA+AA of rs699947 were more frequent in patients with colonic CD compared with the controls (P=0.006, 95%CI1.143-2.234; P=0.005, 95%CI1.203-2.900, respectively). Compared with the controls, the allele A and genotype CA+AA of rs699947 were less frequent in patients with ileal lesions including ileal CD and ileocolonic CD (P=0.033, 95%CI0.524-0.974;P=0.043, 95%CI0.481-0.989, respectively). The frequency of TT homozygote of rs3025039 was lower in patients with non-stricturing and non-penetrating CD compared with the controls (P=0.036, 95%CI0.016-0.870).</p><p><b>CONCLUSION</b>Polymorphisms of the VEGF gene rs699947 locus may contribute to an increased risk for colonic CD, but may play a protective role in patients with ileal lesion. Individuals carrying the TT genotype for VEGF rs3025039 locus may be less susceptible to non-stricturing and non-penetrating CD.</p>
