To the Editor:

We thank the authors of “CTNBB1 mutations in papillary thyroid carcinoma with prominent myofibroblastic stromal component” for their short correspondence in which they identify an error in Fig. 4 of the original paper [1, 2]. The original sequencing report was reviewed and shows a CTNNB1 c.124A>G (p.Thr41Ala) mutation that was reported incorrectly in the original report. This was a typographical error in the original report. Review of the sequencing data for case 3 shows this should have indeed been a CTNNB1 c.121A>G (p.Thr41Ala) mutation. This mistake was unfortunately transcribed and propagated into Table 3 and Fig. 4 and not caught during review of the Table and Figure. Table 3 and Fig. 4 have been revised (see Table 1 and Fig. 1). The body of the manuscript requires no revisions. The overall study findings remain unchanged.
