Additional notable recurrent rare SVs included an exonic insertion of a non-coding RNA, MIR137, which has been shown to play a significant role in neural development and neoplastic transformation19, splicing inversion in DRD4 which has previously been implicated in ADHD20, and an exonic translocation of BPTF, which causes expressive language delay and intellectual disability21. The gene discussed is BPTF; the disease is Expressive language delay.
