Retinoic acid-induced protein 1 is a transcription factor that in humans is encoded by the RAI1 gene. Mutations or copy number alterations affecting this gene are associated with neurodevelopmental disorders. Deletions of RAI1 are a primary cause of Smith–Magenis syndrome,^[5]^[6] whereas duplications of the gene are associated with Potocki–Lupski syndrome.^[7]
