Among both TNBC and non-TNBC cases, the presence of the TIMP-2 rs8179090 homozygous variant CC genotype showed significant associations with BC and TNBC (OR = 2.63 and 3.48, 95%CI = 1.67–4.14 and 1.79–6.76, p = 0.0001 and 0.0003) (Table 8). The gene discussed is TIMP2; the disease is breast cancer.
