Differences between methods were particularly marked in the thyroid papillary microcarcinoma group; BRAF p.V600E mutations were found in 37% of patients using Seq and 63% and 66% of patients using ASA-PCR and qPCR, respectively.
Papillary microcarcinoma in comparison with larger papillary thyroid carcinoma in BRAF(V600E) mutation, clinicopathological features, and immunohistochemical findings.
BRAF(V600E) mutation and the previously unreported BRAF(G593D) mutation along with p.G606G silent change were found in the second papillary microcarcinoma, but no mutations were detected in the follicular adenoma or in the 2 other pools of solid cell nests screened for BRAF gene mutations.
