Abstract: Increased production of matrix metalloproteinases (MMPs) plays an important role in tissue damage in inflammatory bowel disease (IBD). Genetically encoded variation between individuals in MMP production may therefore contribute to disease onset, type, or severity. We undertook an extensive candidate gene single nucleotide polymorphism (SNP) study of MMP-1, -2, -3, -7, -8, -9, -10, -12, -13, and -14 and tissue inhibitor of metalloproteinases (TIMPs)-1, -3, and -4 in ulcerative colitis (UC). We identified tagging SNPs across these genes, and genotyped these SNPs in a Caucasian New Zealand dataset consisting of 419 UC patients and 907 controls. SNPs in a number of MMP genes were associated with UC. After correcting for multiple testing SNPs in MMP-3, MMP-8, MMP-10, and MMP-14 remained significant in their associations with UC. In a second study, using samples from a Dutch cohort, most of the significant findings in the New Zealand cohort were not replicated. However, data from an international meta-analysis provide some support for the initial findings. In conclusion, this study provides preliminary evidence to suggest that genetic variation in the MMPs may play a role in interindividual differences in UC susceptibility and clinical outcome. Further studies are needed in other cohorts to determine the robustness of these observations in different populations.
