Identification of somatic KRAS mutations by targeted next-generation sequencing from a set of three colorectal cancer (CRC) samples. The green letter A and red letter T indicate the presence of a non-reference allele. Somatic point mutations of C>A at 25,398,284 bp for CRC-1, C>A at 25,398,285 bp for CRC-2, and C>T at 25,398,281 bp for CRC-3 were found in KRAS on chromosome 12.
