The source of the variation in DNA methylation is not known for either of these diseases, but possibilities include stochastic changes or embedded environmental signatures. Future work on the MHC region will be required to elucidate whether environmental exposures alter DNA methylation in that area, as well as whether these can be mitigated to alter disease trajectory. One of the first autoimmune diseases predicted to have an epigenetic contribution was systemic lupus erythematosus. Potential environmental contributions have led researchers to examine DNA methylation patterns to determine whether genes involved in the production of anti-nuclear antibodies are differentially methylated in lupus patients [55].
