Gene length matters in neurons

Abstract

A recent study by Gabel etal. (2015) found that Mecp2, the gene mutated in Rett syndrome, represses long (>100 kb) genes associated with neuronal physiology and connectivity by binding to methylated CA sites in DNA. This study adds to a growing body of literature implicating gene length and transcriptional mechanisms in neurodevelopmental and neurodegenerative disorders. A recent study by Gabel etal.
