“… 4 In addition, alterations such as mutations, chromosomal structural variants, microsatellite instability, gene fusions, altered gene expression, and epigenetic inactivation in cancer hallmark genes have been implicated in CRC development. 5 In the case of CRC, earlier studies have identified alterations in genes such as KRAS, NRAS, c-Myc, APC, TP53, CTNNB1, PIK3CA, and mismatch repair (MMR) genes with significant frequency in the number of CRC cases. 6 , 7 In recent years, researchers have also identified several new genes that serve as a potential therapeutic target (e.g., LGR4-6, RNF43, ZNRF3, RSPO2, ANO5, SLITRK1, NRXN1, and ANK2) and are linked to the CRC development.…”
