There are 2 genes in common (PROM1, GPM6B) with the 339 probe sets used to develop our diagnostic classifier [13]; 3 genes (SEL1L3, KRT19, and KRT7) in common with the 119 genes differentially expressed gene of Joesting et al.[29], and 3 genes (NKX3-1, TPD52, and GALNT3) in common with the 44 genes that were differentially expressed between tumor-associated stroma and nontumor stroma from 5 patients [30]. The gene discussed is KRT19; the disease is neoplasm.
