INGX and neoplasm: With the exception of two probes (found in the promoters of genes DFCAF12L2 and INGX), which were highly methylated in all samples, the remaining 20 probes showed the expected behavior in tumor-adjacent normal tissue in that they were substantially unmethylated in male tissue and about 50% methylated in females (similar pattern to the probes profiled in Fig. 3e, f).
