Autism has been described in patients with SSRIDD, especially among patients with mutations in ARID1B. This observation is mirrored by the findings of De Rubeis et al. (2014), who found ARID1B among the high risk genes for autism, defined by two or more de novo loss-of-function mutations among 2270 children with ASD. The gene discussed is ARID1B; the disease is atrial septal defect.
