WebJan 24, 2024 · Horvath hypothesized that DNA methylation age measures the status of a person’s epigenetic maintenance system and its cumulative effects. However, what exactly is measured is still unknown. In 2024, Horvath and Raj proposed an epigenetic clock theory of aging [iii] . They state that DNA methylation age can predict accurate age.
