The results of the KRAS mutational analysis have shown that the majority of somatic mutations in the KRAS affect only one codon, mainly codon 12(p.G12D) with low frequency in adenomas (13.3%) versus CRCs (36%).

The US Food and Drug Administration approved a liquid biopsy test for EGFR-activating mutations in patients with non-small-cell lung cancer as a companion diagnostic for therapy selection. ctDNA also allows for the identification of mutations selected by treatment such as EGFR T790M in non-small-cell lung cancer. ctDNA can also detect mutations such as KRAS G12V in colorectal cancer and BRAF V600E/V600K in melanoma.

Moreover, comparison of the survival of patients with tumors harboring G12V/A KRAS mutations with those harboring wild-type KRAS gene revealed that G12V/A KRAS mutations are prognostic biomarker for inferior PFS and OS in patients with mCRC treated with bevacizumab in univariate as well as multivariable analyses.

Recent evidence associates the codon 12 valine-for-glycine (G12V) mutant Ki-Ras protein with higher stage and increased lethality of colorectal carcinomas, while the codon 12 aspartate-for-glycine (G12D) Ras mutation shows no such association.

To accomplish this, we first carried out an in silico analysis of RNA-seq databases and found that the distribution of alternative splicing isoforms of genes RPL13, HSP90B1, ENO1, EPDR1 and ZNF518B was altered in human CRC cell lines carrying the G13D KRAS mutation when compared to cell lines carrying wild-type KRAS.
