Abstract
Epigenetic events including chromatin remodeling and histone modifications have recently emerged as important contributors to a variety of neurodevelopmental disorders. This review focuses on CHARGE syndrome, a multiple anomaly condition caused by mutations in the gene encoding CHD7, an ATP-dependent chromatin remodeling protein. CHD7 exhibits pleiotropic effects during embryonic development, consistent with highly variable clinical features in CHARGE syndrome. In this review, a historical description of CHARGE is provided, followed by establishment of diagnostic criteria, gene discovery, and development of animal models. Current understanding of epigenetic CHD7 functions and interacting proteins in cells and tissues is also presented, and final emphasis is placed on challenges and major questions to be answered with ongoing research efforts.

Zentner and colleagues demonstrate that CHD7 binds to “poised” enhancers, which show preference for regulation of ectodermal derivatives. This study, combined with their earlier reports, confirm that CHD7 has a broad repertoire of binding sites in the mammalian genome, including transcription start sites and enhancer regions.

Hum Mol Genet. 2014; 23(2):434–448 The authors of this study provide the first evidence that changes in retinoic acid signaling can influence the developmental effects of CHD7 on inner ear development. Using a combination of mouse genetics and in vitro neural stem cell assays, they show that CHD7 is a key regulator of neural stem cell proliferation and that CHD7 deficiency leads to impaired neuronal development in the brain.

In this paper, the authors highlight the significant phenotypic similarity between CHARGE and Kabuki syndrome. Kabuki syndrome is caused by mutations in the KMT2D gene, which encodes a H3K4 histone methyltransferase. The authors further demonstrate that CHD7 and KMT2D also share interacting protein partners.
