This review explores the commonalities and differences between autism and RTT at clinical and molecular levels with respect to current status and challenges for each, highlights recent findings from the Rare Disease Network Natural History study on RTT, and summarizes the broad range of phenotypes resulting from mutations in the methyl-CpG-binding protein 2 gene (MECP2), which is responsible for RTT in 95% of individuals with the disorder.
