Gene Description | BRAF, serine/threonine-protein kinase B-raf, is a member of the Raf family of serine/threonine protein kinases, which signals through the MAP kinase pathway to regulate cell proliferation and cell growth (PMID: 24737949, PMID: 29540830). BRAF mutations and fusions have been identified in a variety of cancers, including, colorectal (PMID: 30122982), lung (PMID: 29729495), thyroid (PMID: 12970315), and melanoma (PMID: 24737949), and a number of mutations have also been demonstrated to confer drug resistance (PMID: 27478040). | ||||||||||

act mut | unknown | gain of function | BRAF act mut indicates that this variant results in a gain of function in the Braf protein. However, the specific amino acid change has not been identified. | |
class 1 | unknown | gain of function | BRAF Class 1 variants are BRAF variants that activate BRAF and downstream signaling in a dimer-independent, RAS-independent manner (PMID: 28783719, PMID: 26343582). | |
class 2 | unknown | gain of function | BRAF Class 2 variants are BRAF variants that activate BRAF and downstream signaling in a dimer-dependent, RAS-independent manner (PMID: 28783719, PMID: 26343582). | |
class 3 | unknown | loss of function | BRAF Class 3 variants are BRAF variants that demonstrate low or no BRAF kinase activity, but activate downstream signaling through CRAF activation, in a dimer-dependent, RAS-dependent manner (PMID: 28783719). | |
D594X | missense | unknown | BRAF D594X indicates any BRAF missense mutation that results in replacement of the aspartic acid (D) at amino acid 594 by a different amino acid. | |

G466X | missense | unknown | BRAF G466X indicates any BRAF missense mutation that results in replacement of the glycine (G) at amino acid 466 by a different amino acid. | |
G469X | missense | unknown | BRAF G469X indicates any BRAF missense mutation that results in replacement of the glycine (G) at amino acid 469 by a different amino acid. | |
G596fs | frameshift | loss of function - predicted | BRAF G596fs results in a change in the amino acid sequence of the Braf protein beginning at aa 596 of 766, likely resulting in premature truncation of the functional protein (UniProt.org). Due to disruption of the protein kinase domain (UniProt.org), G596fs is predicted to lead to a loss of Braf protein function. | |

Due to the loss of the protein kinase domain (UniProt.org), P403fs is predicted to lead to a loss of Braf protein function. | |
