It is important to emphasize that the BC risk allele c.836 A (rs17576) MMP9 (according to our data, the reference allele G of this SNP is protective) determines the high transcriptional activity (β > 0) of the overwhelming number of the abovementioned genes (five out of seven); only the adipose expression of two genes (SLC12A5, and CD40) is negatively associated with this allele (β < 0). The gene discussed is SLC12A5; the disease is breast cancer.
