Recently, a significant PRDM5 promoter methylation was observed in BRAF mutant cancers of the serrated pathway whereas minimal levels of methylation were detected in the BRAF wild-type cancers of the traditional pathway; moreover, PRDM5 methylation was evident in a small proportion of serrated type polyps indicating that this may be an early event in tumorigenesis [135]. This evidence concerns the gene PRDM5 and cancer.
