Regional association plot for single nucleotide polymorphisms (SNPs) in
TGFBR2. The regional plot shows associations with overall survival in ER-negative breast cancer patients who received adjuvant chemotherapy, for all SNPs in TGFBR2. The y-axis shows the -log10 P-value. The purple diamond indicates SNP rs1367610, with the most significant association in TGFBR2. Chr, chromosome.
