In the published article, there is an error in Figure 3 and Figure 4 as published. The two figures are inverted, while the captions are correct. The corrected Figure 3 and Figure 4 and its caption appear below.
FIGURE 3

Chromosome 15q13.3 and hiPSCs derived from individuals with CNV. Graphic representation of chromosomal region 15q13.3 showing BreakPoint regions BP3, BP4 and BP5 and the extensions the microdeletions and microduplications present in the hiPSCs in the published studies.
FIGURE 4

An insight into molecular effects of CNV 15q13.3. Cells carrying CNV duplications show decreased calcium flux associated with the α7 receptor, downregulation of JAK2-PI3K pathway, decreased assembly and trafficking of nAchRs, and ER stress. Cells carrying CNV deletions exhibit decreased α7nAchRs calcium flux and downregulation of JAK2-PI3K pathway.
In the published article, there is an error in Table 1 as published. The table is not paginated correctly.Table 1 and its caption appear below.
