This gene encodes a protein belonging to the RAF family of serine/threonine protein kinases. This protein plays a role in regulating the MAP kinase/ERK signaling pathway, which affects cell division, differentiation, and secretion. Mutations in this gene, most commonly the V600E mutation, are the most frequently identified cancer-causing mutations in melanoma, and have been identified in various other cancers as well, including non-Hodgkin lymphoma, colorectal cancer, thyroid carcinoma, non-small cell lung carcinoma, hairy cell leukemia and adenocarcinoma of lung. Mutations in this gene are also associated with cardiofaciocutaneous, Noonan, and Costello syndromes, which exhibit overlapping phenotypes. A pseudogene of this gene has been identified on the X chromosome. [provided by RefSeq, Aug 2017]

BRAF rearrangements are found in about 20% of acinar-type neoplasms, and may serve as a potential treatment target. This study examined the efficacy of FISH versus NGS for detecting BRAF translocations in 31 acinar-type neoplasms. As part of FISH analysis, our BRAF break apart probes were used to detect BRAF rearrangements. The team found that, compared to NGS, FISH was highly sensitive, specific, and time- and cost-effective.
Pilocytic astrocytoma (PA) is a type of brain tumor. Certain molecular abnormalities can be indicative of PA such as alternative lengthening of telomeres or loss of ATRX. In many cases of PA, there is a duplication in the kinase domain of the BRAF gene called KIAA1549_BRAF. Red and green FISH probes were used to identify this BRAF gene duplication. The duplication was found to be present in 31% of the PA patients.
Atypical spitzoid neoplasms (APNs) are primarily pediatric lesions characterized by their intermediate features; clinically and histopathologically, they fall somewhere between benign spitz nevi and malignant melanoma. The genetics of these tumors are still poorly understood. In this study, 34 APNs were analyzed using FISH and IHC. Our ALK, BRAF, and NTRK1 break-apart FISH probes were used to detect rearrangements of the genes .
Histiocytic sarcoma (HS) is a rare, aggressive cancer that can occur in the GI tract, skin and liver. This study analyzed 21 cases of HS using RNA sequencing, whole exome sequencing, and FISH. BAC FISH probes from Empire Genomics were used to detect NF1 (RP11-14206) and PTNP11 (RP11-748H13, RP11-9P8, RP11-90F3, RP11-660M3), while BRAF translocations were identified using our BRAF break-apart probe. The team found many abnormalities within the RAS-RAF-MAPK pathway in all 21 cases, with aberrations in NF1 (6/21), MAP2K1 (5/21), PTPN11 (4/21), BRAF (4/21), KRAS (4/21), NRAS (1/21) and LZTR1 (1/21).
