MDM2 and cancer: Therefore, we investigated HPV prevalence and genotype distribution in cervical cancer as well as the association with 9 genetic single nucleotide polymorphisms (SNPs): CDKN1A (p21) C31A, TP53 C72G, ATM G1853A, HDM2 promoter T309G, HDM2 A110G, LIG4 A591G, XRCC1 G399A, XRCC3 C241T and TGFβ1 T10C, presumed to predispose to cancer.
