The role of maternal folate status in child risk of autism has received great attention and is in debate. While many studies suggest beneficial effect of higher maternal folate intake against autism, a few studies raised concern about the potential harm of high prenatal folate intake. Our preliminary data suggest that maternal folate intake may have an impact on RNA methylation metabolism. This proposal aims at the determination of association among functional RNA methylation, maternal folate status, and child risk of autism spectrum disorders (ASD). The methodologies developed by our study will be helpful to investigate molecular underpinnings of other micronutrients or toxicants on neuro-development outcomes.
