KRAS and neoplasm: One was the A:T > T:A transversion of in codon 16 resulting in the truncation (AAG > TAG; Lys > Stop) of Kras protein in two tumor tissues and second was the C:T > T:C transition at codon 19 leading to change of leucine to phenaylalanine (CTT > TTT) in two tumor tissues [Table 2, Figures 3 &4].
