Since whole genome sequencing is expensive, we used mass spectrometric single nucleotide polymorphism genotyping technology for multiplex analysis, which included 68 validated mutations within eight genes (TP53, ARID1A, BRAF, and the PI3K/AKT pathway) [8] in accordance with previous data that mutations in these genes were shown for cancers related or non-related to the gastrointestinal tract. Here, TP53 is linked to cancer.
