Real-Time Polymerase Chain Reaction (RT-PCR)
BRAF V600E mutations are found in 40-50% of papillary thyroid carcinoma (PTC), and much less commonly in anaplastic thyroid carcinoma or poorly differentiated carcinomas involving the thyroid. Correlation with morphologic and clinical findings is thus required. Cases of PTC with BRAF V600E mutation may be associated with more aggressive tumor characteristics and higher rates of recurrence and treatment failure. The assay tests for codons 600 and 601 BRAF mutations using a DNA-based mutation-specific PCR method, with an approximate sensitivity of 0.1% mutation-bearing cells in a mixed sample. BRAF mutations outside of these codons will not be detected.
