Abstract excerpt
Estrogens play a central role in the etiology of breast cancer. The CYP19A1 gene encodes aromatase, a key enzyme in the biosynthesis of estrogens. Several single nucleotide polymorphisms (SNP) or haplotypes in the CYP19A1 gene have been evaluated in relation to breast cancer risk. However, the results have been inconsistent. In this study, we constructed haplotypes of the CYP19A1 gene using 19 haplotype-tagging...
