BRAF Mutation Analysis, Papillary Thyroid Cancer
Test Code
Clinical Significance
BRAF Mutation Analysis, Papillary Thyroid Cancer - 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.
