BRAF CODON 600 VARIANT TESTING IN MALIGNANT MELANOMAS TO PREDICT RESPONSE TO BRAF KINASE INHIBITORS Approximately 40 to 60% of cutaneous melanomas carry activating variants in BRAF that lead to the constitutive activation of downstream signaling through the MAPK pathway. Approximately 90% of these variants result in the substitution of glutamic acid for valine at codon […]
ViewANALYSIS OF CODONS 12, 13, 59, 61, 117 AND 146 OF THE KRAS GENE, CODONS 12, 13, 59 AND 61 OF THE NRAS GENE AND CODON 600 OF THE BRAF GENE Activating somatic KRAS gene variants are found in 30-40% of colorectal tumours. These variants typically occur in codons 12, 13 (exon 2), 59, 61 (exon 3) 117 or […]
