In addition, oligonucleotide microarray analysis of distinct gene expression patterns in CRC tissues harboring BRAF and K-ras mutations has shown that FOXJ3 was identified by PAM (Prediction analysis of microarrays) and the jackknife (or leave-one-out) cross validation as candidate to distinguish the mutant groups [102]. The gene discussed is KRAS; the disease is colorectal carcinoma.
