Methylation for PON1 (associated with neurobiological development, neurodegenerative disease), FGFR2 (associated with obesity and depression), and WNK4 (associated with hypertension and obesity) in the mother data, and ZFP57 (associated with post-traumatic stress disorder) in the child data were correlated to maternal exposure to adverse life events. This evidence concerns the gene ZFP57 and neurodegenerative disease.
