In this analysis, expression of 2 genes (CENPF, PLXNA1) showed significant differences between groups that died from breast cancer (n = 388) vs alive/lost to follow up (n = 962) (p < 0.05), and significantly predicted differences in length of survival in Kaplan–Meier analyses (p < 0.05) (Fig. S2). The gene discussed is PLXNA1; the disease is breast cancer.
