This study has confirmed the high prevalence of BRAF(V599E) in PTC and has shown that the mutation is almost exclusively seen in PTC with a papillary or mixed follicular-papillary growth pattern, regardless of the cytological features of the neoplastic cells.

We conclude that the frequency of BRAF mutations is significantly lower (P = 0.0008) in post-Chernobyl PTC than in adult sporadic PTC, whereas no significant difference was found between post-Chernobyl and sporadic childhood PTCs.
