Figure 2A shows the number of genes per copy number variant (CNV) for all significant CNVs in autism spectrum disorder (ASD), intellectual disability (ID), schizophrenia (SZ), and epilepsy (EP) and is separated into deletions (red) and duplications (blue). Note: The median number of genes per CNV is shown in the center of each box and the whiskers indicate the range. Figure 2B shows the number of CNV categories (e.g. A, B, and C) for all 4 disorders. ID had a greater number of category A CNVs in both ASD (p=.004) and epilepsy (p<.001). Also, ID had a significantly greater number of category C CNVs for ASD (p=.04) and epilepsy (p=.002).
