CTNNB1 and neoplasm: The tumor from P05 harbored a mutation in CTNNB1 (c.1147T > G, p.Trp383Gly) with 48.6% of VAF, and tumor from P06 presented two mutations: one in CTNNB1 (c.1149G > T, p.Trp383Cys, affecting the same codon of tumor from P05), and one in WTX (c.1057C > T, p.Arg353*) with VAFs of 47.30% and 45.82%, respectively.
