The genes with the highest centrality values (B ≥0.1) in G1 are PSMG3, HJURP, BEND3, C10orf2, TPX2, RRP12 and DNMT3B; in G2, CXCR6, HCST, C3AR1, GBP4, LY96, ANKRD22, FPR3 and FCGR2A; and in G3, CTSK. Within this set, the genes HJURP, RRP12, DNMT3B, CXCR6, HCST, C3AR1, FPR3 and CTSK also showed high node degree values (ND ≥4), representative for probe co-expression, corroborating with their key role on the differentiation of basal-like carcinomas. The gene discussed is RRP12; the disease is carcinoma.
