Specifically, in the meta-analysis by Paracchini and colleagues, a lack of association between the CYP1B1 Val432Leu (i.e., C→G transversion at position 1666 in exon 3, resulting in an amino acid substitution of leucine (Leu) with valine (Val) at codon 432; rs1056836, NC_000002.12:38071059:G:C) polymorphism and BC was observed in Asian individuals, whereas in populations of mixed/African origin, a negative correlation emerged (OR = 0.8; 95% CI: 0.7–0.9; p < 0.05). Here, CYP1B1 is linked to breast cancer.
