Test ID: BRAF
BRAF Mutation Analysis (V600E), Tumor
Secondary ID 
A test code used for billing and in test definitions created prior to November 2011
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/17073 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/87931 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.
