The heatmap show the normalized coefficient of the gene in Cox model as seen in Figure 4A. Results indicated that ATM (Figure 4B) and SEPP1 (Figure 4E) genes induced significant (p < 0.05) increased risk in BRCA-LumA patients than other type of breast cancer patients while GABARAP (Figure 4C) gene induced significant (p < 0.05) decreased risk in all BRCA patients, but IL7R (Figure 4D) in only BRCA-LumB patients. The gene discussed is IL7R; the disease is invasive breast carcinoma.
