Genotype analysis of the human GPx-1 polyalanine polymorphism in breast cancer samples and cancer-free individuals

DNAs were genotyped to determine the number of alanine codon repeats in the gene for human GPx-1 as described in the text, and the data presented in the table represent the determined genotypes for individuals analyzed.
