What cancers have BRAF mutations?
BRAF mutation is seen in melanoma, papillary thyroid carcinoma (including papillary thyroid carcinoma arising from ovarian teratoma), ovarian serous tumours, colorectal carcinoma, gliomas, hepatobiliary carcinomas and hairy cell leukaemia.
How does BRAF cause cancer?
Somatic mutations cause the BRAF protein to be continuously active and to transmit messages to the nucleus even in the absence of these chemical signals. The overactive protein may contribute to the growth of cancers by allowing abnormal cells to grow and divide without external signals.
What does it mean if you are BRAF positive?
A BRAF mutation is a change in a BRAF gene. That change in the gene can lead to an alteration in a protein that regulates cell growth that could allow the melanoma to grow more aggressively. Approximately half of melanomas carry this mutation and are referred to as mutated, or BRAF positive.
What causes a BRAF mutation?
A BRAF mutation can be inherited from your parents or acquired later in life. Mutations that happen later in life are usually caused by the environment or from a mistake that happens in your body during cell division. Inherited BRAF mutations are very rare, but they can cause serious health problems.
How should BRAF V600E mutated colorectal cancer be treated?
BRAF mutated CRC has unique clinical, morphological, and therapeutic characteristics that differentiate it from the other described molecular subtypes. The classic treatment has been based on a combination of chemotherapy treatments with anti-VEGF monoclonal antibodies.
How much does a BRAF test cost?
BRAF testing costs about $200-$300. If the BRAF testing is negative, testing should proceed for the MLH1 gene, to confirm Lynch Syndrome.
How is BRAF mutation detected?
The test for BRAF mutation can be applied to fresh, frozen or, more commonly, formalin-fixed, paraffin embedded (FFPE) tumor. The V600E mutation is the primary mutation tested for commercially. The most commonly used technique to identify BRAF mutation is real-time polymerase chain reaction (PCR).
What happens when BRAF is mutated?
A specific mutation (change) in the BRAF gene, which makes a protein that is involved in sending signals in cells and in cell growth. This BRAF gene mutation may be found in some types of cancer, including melanoma and colorectal cancer. It may increase the growth and spread of cancer cells.
What does BRAF mean in medical terms?
Definition of BRAF
BRAF (v-raf murine sarcoma viral oncogene homolog B1) is a serine/threonine protein kinase that plays a critical role in the RAS-RAF-MEK-ERK mitogen activated protein kinase (MAPK) cell signalling pathway.
