Potential Methylation Sites in the MT-Dloop: Recent studies have shown that differential levels of methylation at specific CpG and Non-CpG sites can account for varying occurrences in diseases such as laryngeal squamous cell carcinoma, prostate cancer, colorectal cancer, and systemic lupus erythematosus [66,67,68]. This evidence concerns the gene MCAT and laryngeal squamous cell carcinoma.
