BRAF fusion

Saturday 4 January 2014

MAPK pathway activation


- BRAF-AKAP9 fusion gene (15630448) in thyroid carcinomas

- PAPSS1-BRAF and TRIM24-BRAF fusion gene in melanoma

  • BRAF fusions define a new molecular subset of melanoma, potentially comprising 4% to 8% of "pan-negative" cases.
  • Their presence may explain an unexpected clinical response to MEK inhibitor therapy or assist in selecting patients for MEK-directed therapy.

- KIAA1549-BRAF gene fusion (KIAA1549 andBRAF )
