An independent group comparison of basal-like (N = 32) and luminal A (N = 76) subtypes, which have the most abundant patient samples, indicates that BACH1 IHC scores were significantly higher in the basal-like tumor subtype (p < 0.001, Rank-Biserial Correlation = 0.517) (Figure 2B). The gene discussed is BACH1; the disease is neoplasm.
