Examples of KRAS mutations. a A representative example of a chromatogram. A KRAS mutation (c.183A > C; p.Q61H) in exon 3 as detected by Sanger sequencing is depicted (arrow). Each mutation was observed on the forward and the reverse strand. b An example of a chip-hybridization result from one patient. On top 3 type-specific double signals (arrowhead). On the left, the mutation-specific double signal (c35G > T; p.G12V) (arrow)
