In vivo epigenetic editing of Sema6a promoter reverses transcallosal dysconnectivity caused by C11orf46/Arl14ep risk gene

Although many neuropsychiatric risk genes are known to contribute to epigenetic regulation of gene expression, very little is known about specific chromatin-associated mechanisms that govern the formation and maintenance of neuronal connectivity. Here, the authors report that transcallosal connectiv...

Sumario:Although many neuropsychiatric risk genes are known to contribute to epigenetic regulation of gene expression, very little is known about specific chromatin-associated mechanisms that govern the formation and maintenance of neuronal connectivity. Here, the authors report that transcallosal connectivity is critically dependent on C11orf46/ARL14EP, a nuclear protein encoded in the chromosome 11p13 WAGR risk locus, and that RNA-guided epigenetic editing of hyperexpressed Sema6a gene promoters in C11orf46-knockdown neurons resulted in normalization of expression and rescue of transcallosal dysconnectivity via repressive chromatin remodeling.
