While identification of epigenetic changes in individuals with psychiatric dysfunctions such as post-traumatic stress disorder (PTSD) is paramount to genomic research, there is no rapid and simplified way to detect an epigenetic marker such as DNA methylation in genes. Here, we introduce a faster, simpler method to detect methylation in the form of 5-methylcytosine (5mC, termed as PTSD-associated base) in known C
