Lymphoblastoid cell lines (LCLs) were established from the peripheral blood of the two patients (Case #4 and #5) with exonic CNVs in ARHGAP10. The relative expression levels of ARHGAP10 mRNA in patients with ARHGAP10 deletion were significantly decreased compared with those in the schizophrenia group and control group (Supplementary Fig. 1e, f). The gene discussed is ARHGAP10; the disease is schizophrenia.
