Using data from the Adolescent Brain Cognitive Development Study® (Casey et al., 2018; Jernigan, Brown, & Dowling, 2018), we previously investigated the associations between the FAAH C385A polymorphism, anxiety symptoms, and frontolimbic white matter pathways (structural connections) in children aged 9–11 years (Marusak, Evanski, Desai, & Rabinak, 2022). Here, FAAH is linked to Anxiety.
