To further understand the relevance of the top five hub genes in cancers, we interrogated the PRECOG (PREdiction of Clinical Outcomes from Genomic profiles) database, which encompasses 166 cancer expression datasets, including overall survival data for ≈18 000 patients diagnosed with 39 distinct malignancies.[16] Our analysis revealed that HSP90AA1 had the highest unweighted meta‐Z score, followed by YWHAG, MRPS15, and POLR1B. The gene discussed is POLR1B; the disease is cancer.
