FGFR3 and neoplasm: In our 15 tumor samples, the most recurrently mutated genes were FGFR3 and CDKN2A and the only recurrent mutation was p.Ser249Cys in FGFR3. Despite reports in the literature suggesting that mutations of TP53 are frequent in TCs (approximately 25%), we did not observe point mutations in this gene.
