NDRG1 and cancer: We then investigated the relationship of MYC and NDRG1 amplifications with the HRD score using pan-cancer data, and the results were per our hypothesis: MYC and NDRG1 amplifications are significantly correlated with HRD score (MYC: rho = 0.6809, p = 0.0001; NDRG1: rho = 0.6453, p = 0.0004; Figures 4C, E; Spearman’s rank correlation).
