are mutations in the BRAF gene. Occurring in approximately 50% of PTC patients, the BRAF mutation causes constitutive activation of the MAP-kinase pathway, leading to increased propensity for tumor cell proliferation ( 16 , 17 ). Although the

pathogenesis in PTC. Several genetic alterations have been described in PTC ( 4 ). Among them, BRAF mutation, especially BRAF V600E , is the most common mutation in PTC; however, its prognostic role in PTC is still debated ( 5 , 6 , 7 ). Another recently
