RAS/RAF Panel
- Next Generation Sequencing (NGS)
The RAS/RAF Panel is an NGS-based assay performed by sequencing the entire coding region (full gene) of BRAF, HRAS, KRAS and NRAS genes. The panel reports mutations detected in the full gene including mutations in the most common hotspots, if present. The common hotspots include KRAS (exons 2-4, including codons 12, 13, 59, 61, 117, and 146), NRAS (exons 2-4, including codons 12, 13, 59, 61, 117, and 146), HRAS (exons 2-3, including codons 12, 13, 59, and 61), and BRAF (exons 11, 15 including codon V600).
