The common clinical features of the 17q12 recurrent duplication are variable ranging from normal to severe intellectual disability, epilepsy, and other clinical manifestations. Speech delay is common, and most affected individuals have some degree of gross motor delay. Seizures are present in 75%. Up to one third have eye or vision problems; cardiac and renal anomalies occur in rare cases. Other neurodevelopmental and psychiatric conditions reported in a subset of affected individuals are autism spectrum disorder, schizophrenia, and behavioral abnormalities (aggression and self-injury). The 17q12 recurrent duplication likely has reduced penetrance and variable expressivity since it is inherited in most instances from a parent who is often minimally affected or phenotypically normal (GeneReviews: https://www.ncbi.nlm.nih.gov/books/NBK344340/ ).
