SLC22A17 and cancer: To better understand the regulatory role of the CG probesets, taking into account their relative position within the SLC22A17 locus, differential analysis of SLC22A17 expression was performed by stratifying the TCGA Pan-Cancer SKCM samples into five groups according to the median methDNA levels of all the CG probesets pooled into promoter and body groups (Fig. 2D).
