7 differentially methylated loci between PD individuals with 10+ vs. 0 years of plantation work exposure8 differentially methylated loci between PD individuals with 4+ vs. 0–2 organochlorines in the brain2 different loci annotated to DNAJC15 which were differentially methylated (in both brain and blood) between the organochlorine exposure groups. Here, DNAJC15 is linked to Parkinson disease.
