For all breast cancer types, our analysis showed significant inverse correlation of the TRPV6 mRNA level with the overall survival rate (HR = 1.58, 1.25–1.99; p = 8.8e-05) and the relapse-free survival rate (HR = 1.45, 1.29–1.63; p = 6.9e-10), with a 95% confidence interval (Fig. 7a, b). This evidence concerns the gene TRPV6 and breast carcinoma.
