Using iPSCs and genomics to catch CNVs in the act.

Large copy number variants (CNVs) are strongly associated with morphogenetic processes and common neurodevelopmental disorders. A new study uses the example of Williams-Beuren syndrome (WBS) and Williams-Beuren region duplication syndrome to illustrate how induced pluripotent stem cells (iPSCs) and next-generation genomics can lead to a better understanding of complex genetics.
