Genome-wide association studies furthermore link variation in SLC4A7 to breast cancer susceptibility in women of diverse ethnicities; [12–16] and we recently reported that the level of SLC4A7 mRNA in human primary breast cancer biopsies predicts survival (hazard ratio 2.14–2.18) of women with luminal A or basal-like/triple-negative breast cancer [17]. The gene discussed is SLC4A7; the disease is breast cancer.
