In urothelial carcinoma (UC), p300 and CBP are often mutated, whereas the GNAT family HATs GCN5 and PCAF (General Control Nonderepressible 5, p300/CBP-Associated Factor) are often upregulated.
This allowed identifying eight mutations of interest in two patients: FGFR3, PDGFRB, and CREBBP missense single-nucleotide variants (SNVs) in an urothelial carcinoma; FGFR2, FBXW7, TP53, and MLH1 missense SNVs as well as an ATM frameshift mutation in a squamous cell carcinoma of the tongue.
