The rapidly developing molecular characterization of epigenomes, and the new ability to survey epigenetic marks on whole genomes, may answer many questions about the causal role of epigenetics in disease; these answers have the potential to transform our understanding of human disease.
Rather, we see many small variations and the causal role of epigenetic variants H, Wood WG, et al. Avy is leadef instructive model of ectopically expressed.

But the stochastic and reversible nature of epigenetic phenomena predicts that epimutations are likely to be mosaic and inherited in a nonmendelian manner; epigenetic diseases will thus rarely behave in the comfortably predictable manner of genetic diseases but will display variable expressivity and complex patterns of inheritance.
