%0 Journal Article %T A BRAF V600E Mutation in RET-Negative Medullary Thyroid Cancer %A Osuna %A Patricia Mejia %A Robbins %A Richard J. %A Shakil %A Jawairia %A Thomas %A Jessica S. %J - %D 2020 %R https://doi.org/10.1155/2020/7641940 %X We report the case of a woman with a sporadic medullary thyroid carcinoma. Genomic analysis found that her tumor did not contain any common RET mutations but did harbor a BRAF V600E mutation. Only one other well-confirmed example of the BRAF V600E mutation has been reported in an MTC patient. We conclude that this common BRAF mutation may independently drive neoplastic transformation of human parafollicular C cells %U https://www.hindawi.com/journals/crie/2020/7641940/
