Mutation of T to A at 1799 in the exon 15 of the BRAF gene has been reported in 28–69% of papillary thyroid cancer cases, while point mutations of RAS genes are detected in 5–20% (Cohen et al., 2003; Kimura et al., 2003; Namba et al., 2003; Kondo et al., 2007). This evidence concerns the gene BRAF and thyroid gland papillary carcinoma.
