Polymorphism in the hMSH2 gene (gIVS 12-6T→C) and risk of non-Hodgkin lymphoma in a Japanese population

We conducted a hospital-based prevalent case-control study in a Japanese population (cases = 103, controls = 487) to ascertain the previous report about the association between the polymorphism in exon 13 of the hMSH2 gene (gIVS 12-6T→C) and the risk of non-Hodgkin lymphoma in an Ecuadorian population. When the TT genotype was defined as the reference, none of the CT genotypes (OR = 1.52; 95% CI, 0.97–2.37), CC genotypes (OR = 1.06, 95% CI, 0.44–2.54), or CT and CC genotypes combined together (OR = 1.44, 95% CI, 0.94–2.23) demonstrated significant OR. Further investigations with sufficiently larger populations and in other ethnicities are required to verify this association.
