Fortenberry et al. (2014) conducted a study including 264 women (floriculturists and wives of floriculturists) who had been pregnant sometime during the 10 years preceding the study to examine whether maternal and/or child PON1 genotypes (PON1R192Q and PON1L55M) were associated with Attention Deficit Hyperactivity Disorder-Like Phenotypes (ADHD-LP) in a Mexico City, Mexico birth cohort [117]. The gene discussed is PON1; the disease is attention deficit-hyperactivity disorder.
