Other studies showed that the MDM2 SNP309 polymorphism or the p53 common polymorphism at codon 72 is not associated with or only weakly associated with predisposition to carcinomas in other populations (Millikan et al., 2006; Krekac et al., 2008; Tornesello et al., 2009; Zubor et al., 2009). The gene discussed is MDM2; the disease is carcinoma.
