In a ±1000-bp window surrounding the ZNF154 probe cg21790626 site, we evaluated methylation status in 11 CpG nucleotides present on the array (Figure 1a); however, ZNF154 at the position cg21790626, which we previously reported, showed the highest average difference in methylation beta values between tumor and normal samples across all 14 cancer types. The gene discussed is ZNF154; the disease is neoplasm.
