Application of entropy-based statistics for testing gene-gene interaction between SNP309 in MDM2 gene and codon72 polymorphism in p53 gene.

afrequencies were shown as No. of individuals genotyped as TT/TG/GG of MDM2 309T>G in case.bfrequencies were shown as No. of individuals genotyped as TT/TG/GG of MDM2 309T>G in control.1obtained by logistic regression model assuming additive × additive model.2obtained by logistic regression model assuming dominant × dominant model.3obtained by logistic regression model assuming recessive × recessive model.4obtained by logistic regression model by coding genotypes as factors.GCC: gaster cardia cancer; LC: lung cancer; HCC: hepatacelluar cancer; BC: breast cancer.
