Figure 2From: Colorectal carcinomas with microsatellite instability display a different pattern of target gene mutations according to large bowel site of origin Sequence electrophorograms showing KRAS and BRAF mutations. A- Rectal carcinoma presenting the mutation c.35G > A (arrow) in KRAS exon 2 to the left and the normal tissue sample to the right (sequencing analysis is in the reverse direction); B- Sigmoid carcinoma presenting the mutation c.1799T > A (V600E) (arrow) in BRAF exon 15 to the left and the corresponding normal tissue sample to the right.Back to article page
