Modulation of sporadic colorectal cancer risk by polymorphisms and haplotypes of mismatch repair genes
A role of mismatch repair (MMR) in modulating colorectal cancer (CRC) was assessed by genotyping single nucleotide polymorphisms in five MMR genes in hospital-based case- control study. The TAG haplotype in hMSH6 (-556G>T-Ex1-145G>-IVS4-101G>C) decreased a risk of CRC and the GGG haplotype increased a risk of rectal cancer. Although no significant association was found for individual MMR polymorphisms, the hMSH6 haplotypes may modulate the risk of CRC in this population.
