Interestingly, recent studies in pregnant non-human primates have also found that prenatal THC negatively impacts placental function [81] and can alter DNA methylation in genes associated with autism [82] that are related to the SCZ-associated genes found to be differentially expressed in the rodent and human placenta models in this study (i.e., IQGAP1 and VPS33B). The gene discussed is IQGAP1; the disease is autism.
