One SCZ case showed a somatic copy number variant (sCNV) overlapping intron 1 and potentially exon 2 of SORCS2 (Fig. S2A, B), implicated in attention-deficit hyperactive disorder (ADHD), and bipolar disorder (14, 15), though roles of SORCS2 in SCZ are not established. This evidence concerns the gene SORCS2 and attention deficit-hyperactivity disorder.
