    The number of COVID-19 infections [4] are highest in subjects between ages 18–65, while the risk of severe disease or death [4] jumps after age 50 and increases with age. About 35% of patients with symptoms of COVID-19 experience neurological complications.

    Currently many EWAS use blood as a surrogate tissue due to its availability and ease of collection. However, epigenetic changes in the blood may not be associated with the changes in the particular tissue associated with the disease. Many intriguing disorders that could have epigenetic causative factors affect tissues such as brain, lung, heart ...

    The function of DNA strands (yellow) alters depending on how it is organized around histones (blue) that can be methylated (green).. In biology, the epigenome of an organism is the collection of chemical changes to its DNA and histone proteins that affects when, where, and how the DNA is expressed; these changes can be passed down to an organism's offspring via transgenerational epigenetic ...

    en.wikipedia.org/wiki/Epigenetics

    Epigenetic mechanisms. In biology, epigenetics is the study of heritable traits, or a stable change of cell function, that happen without changes to the DNA sequence. [1] The Greek prefix epi-(ἐπι-"over, outside of, around") in epigenetics implies features that are "on top of" or "in addition to" the traditional (DNA sequence based) genetic mechanism of inheritance. [2]

    Epigenetics of human development is the study of how epigenetics (hertiable characteristics that do not involve changes in DNA sequence) effects human development. Development before birth, including gametogenesis , embryogenesis , and fetal development , is the process of body development from the gametes are formed to eventually combine into ...

    The epigenetic marks can result in a wide range of effects, including minor phenotypic changes to complex diseases and disorders. [8] The complex cell signaling pathways of multicellular organisms such as plants and humans can make understanding the mechanisms of this inherited process very difficult. [9]

    Epigenetic modifications both globally and on specific candidate genes are thought to contribute to the etiology of this disease. Immunohistochemical analysis of post-mortem brain tissues across several studies have revealed global decreases in both 5-methylcytosine (5mC) and 5-hydroxymethylcytosine (5hmC) in AD patients compared with controls ...
