Abstract

Retrotransposition in neurons L1 retrotransposons are dynamically regulated and active genomic elements that affect gene expression and neuronal function throughout brain development. According to a new study by Alysson Muotri and colleagues, the absence of MeCP2, a modulator of DNA methylation implicated in several neurodevelopmental disorders, increases L1 retrotransposon activity in rodent models. This increase in susceptibility to L1 retrotransposition is duplicated in iPS cells derived from patients with Rett syndrome. These data correlations suggest that disease-related genetic mutations may influence L1 retrotransposon activity, adding another layer of complexity to our understanding of molecular neurological disorders.
