Molecular epidemiological studies, however, have yielded contradic tory results concerning the potential role of polymorphism rs4430796 in prostate cancer, especially among diverse populations (Gudmundsson et al, 2007b;Thomas et al, 2008;Sun et al, 2008a,b;Levin et al, 2008;Waters et al, 2009;Penney et al, 2009;Yamada et al, 2009;Helfand et al, 2009Helfand et al, , 2010Hooker et al, 2010;Zhou et al, 2011;Liu et al, 2011;Kim et al, 2011;Lange et al, 2012;Chan et al, 2012).
