Similarly, the T allele in CCL5 rs2107538, and the CCL5 rs2280789-G, BC risk allele were also correlated with the low levels of CCL5 mRNA in the blood cells of the BC patients and, in a dose-dependent manner, with the low amounts of CCL5 in the sera of the BC and TNBC patients [30]. This evidence concerns the gene CCL5 and breast cancer.
