There was no significant difference in burden of large, rare CNVs between patients with OCD/TS and controls for CNV rate (average number of CNVs per person), CNV proportion (proportion of samples carrying ≥1 CNV), gene rate (the average number of genes spanned by a CNV), or by restricting to CNVs containing exons (Tables 1, S4, S5, S6; Tables S4–6 appear online). Similarly, no increased CNV burden was identified in secondary, disorder-specific analyses (OCD versus controls or TS versus Controls; Tables S7, S8, available online).
