Test ID: BRAF    
BRAF Mutation Analysis (V600E), Tumor

NY State Approved Indicates the status of NY State approval and if the test is orderable for NY State clients.


Useful For Suggests clinical disorders or settings where the test may be helpful

As an adjunct to HNPCC / Hereditary Nonpolyposis Colorectal Cancer (HNPCC) Screen, when colon tumor demonstrates microsatellite instability (MSI-H) and loss of MLH1 protein expression, to help distinguish a somatic versus germline event prior to performing expensive germline testing


As an adjunct to negative MLH1 germline testing in cases where colon tumor demonstrates MSI-H and loss of MLH1 protein expression


Note: Mayo's preferred screening test (MLBRF / MLH1 Hypermethylation and BRAF Mutation Analyses) includes both MLH1 promoter hypermethylation and BRAF V600E testing.


To identify colon tumors with a previously negative KRAS mutation analysis result that may respond to epidermal growth factor receptor-targeted therapies.


To identify melanoma tumors that may respond to anti-BRAF targeted therapies. Note, this is a laboratory developed test and has not been FDA-approved for this purpose.
