NCIt definition : Human BRAF wild-type allele is located within 7q34 and is approximately 190 kb in
length. This allele, which encodes B-Raf proto-oncogene serine/threonine-protein kinase
protein, plays a role in the transduction of mitogenic signals from the cell membrane
to the nucleus. A specific activating somatic mutation in the BRAF gene is associated
with several types of cancer such as colorectal and thyroid carcinomas and malignant
melanoma.;
NCIt note : Somatic BRAF gene mutations have also been detected in lung adenocarcinoma, non-small
cell lung cancer, non-Hodgkin lymphoma and cardiofaciocutaneous syndrome. Fusion of
the TRIM24 gene with the BRAF gene via translocation results in the production of
a TIF1-alpha-B-Raf oncoprotein.;
