SLC4A7 and breast cancer: The potential importance of these observations was supported when multiple genome-wide association studies (GWAS) subsequently showed that a SNP in the SLC4A7 gene was linked to breast cancer: independent GWAS covering women of European (Ahmed et al., 2009), Korean (Han et al., 2011), Chinese (Long et al., 2010), and Japanese (Sueta et al., 2012) descent showed that the rs4973768 SNP corresponding to the 3′-UTR of SLC4A7 is associated with breast cancer with odds ratios for homozygosity between 1.2 and 1.3.
