The present invention relates to high-throughput methods comprising direct infusion electrospray ionization mass spectrometry (ESI-MS), multistep tandem mass spectrometry (MS
n
), consecutive reaction monitoring (CRM), ion mobility spectrometry mass spectrometry (IMS-MS), high-resolution MS, and IMS-MS, for genome-wide (whole cell or tissue) profiling of DNA and RNA nucleotides/nucleosides having a wide variety of variant structural modifications. In particular, these methods are contemplated for providing a specific profile of variant DNA and/or RNA chemically modified nucleic acids (i.e. structures) associated with specific medical conditions. Medical conditions may include, but are not limited to: cancer; including prostate, lung, uterus, larynx, ovary, breast, kidney, and many other types of cancers; specific stages of cancer; bacterial infections; viral infections; genetic and metabolic disorders; and any condition involving changes in DNA and/or RNA structural modifications.
