Promoter polymorphisms in matrix metallopeptidase 1 and risk of cutaneous melanoma.

ABSTRACT: Matrix metallopeptidase 1 (MMP1) is one of the interstitial collagens in the extracellular matrix metalloproteinase family and involved in tumour behaviours. However, there is no report on the role of genetic variation in MMP1 in risk of cutaneous melanoma (CM). We investigated the association between genotypes and haplotypes of seven reported MMP1 promoter polymorphisms [-1607G ins/del (2G/1G), -839G>A, -755T>G, -519A>G, -422A>T, -340A>G and -320T>C, genotyped by the TaqMan assay] and CM risk in 872 patients and 873 cancer-free controls. These seven polymorphisms were not in linkage disequilibrium among each other (r(2)<0.63). Compared to their common homozygous genotypes, the variant -519GG was associated with significantly decreased CM risk [adjusted odds ratio (OR)=0.71, 95% confidence
