Mutations in this gene have been found in cancers, including non-Hodgkin lymphoma, colorectal cancer, malignant melanoma, papillary thyroid carcinoma, non-small-cell lung carcinoma, adenocarcinoma of the lung, brain tumors including glioblastoma and pleomorphic xanthoastrocytoma as well as inflammatory diseases like Erdheim–Chester disease.
V600E is a mutation of the BRAF gene in which valine (V) is substituted by glutamic acid (E) at amino acid 600. [1] [2] It is a driver mutation in a proportion of certain diagnoses, including melanoma, [3] [4] hairy cell leukemia, [5] [6] papillary thyroid carcinoma, [7] [8] colorectal cancer, [9] non-small-cell lung cancer, [10] [11] Langerhans cell histiocytosis, [12] Erdheim–Chester ...
Thyroid-preserving operations may be applied in cases, when thyroid cancer exhibits low biological aggressiveness (e.g. well-differentiated cancer, no evidence of lymph-node metastases, low MIB-1 index, no major genetic alterations like BRAF mutations, RET/PTC rearrangements, p53 mutations etc.) in patients younger than 45 years.

Dabrafenib is indicated as a single agent for the treatment of people with unresectable or metastatic melanoma with BRAF V600E mutation. [2] Dabrafenib is indicated, in combination with trametinib, for BRAF V600E-positive unresectable or metastatic melanoma, metastatic non-small cell lung cancer, metastatic anaplastic thyroid cancer, and unresectable or metastatic solid tumors.
Papillary thyroid cancer (papillary thyroid carcinoma, [1] PTC) is the most common type of thyroid cancer, [2] representing 75 percent to 85 percent of all thyroid cancer cases. [1] It occurs more frequently in women and presents in the 20–55 year age group.
In addition to these common markers, there are prognostic markers specific to different cancer types. For example estrogen level, progesterone and HER2 are markers specific to breast cancer patients. There is evidence showing that genes behaving as tumor suppressors or carcinogens could act as prognostic markers due to altered gene expression ...
The two are distinct genes in that they're on different chromosomes, but they both cause a syndrome called hereditary breast and ovarian cancer syndrome. The prostate and pancreas are now ...
Due to the importance of both Ras and B-Raf mutations in tumorigenesis, several Raf inhibitors were developed to combat cancer, especially against B-Raf exhibiting the V600E mutation. Sorafenib was the first clinically useful agent, that provides a pharmacological alternative to treat previously largely untreatable malignancies, such as renal ...
