TP53 and thymoma: Furthermore, we found more TP53 mutations in BLCA, HNSC, and KICH, and more mutations of phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha (PIK3CA) in BRCA, more BRAF mutations in THCA, and more mutations of general transcription factor IIi (GTF2I) in thymoma (THYM) in PODNL1 high-expression groups.
