How Rett Syndrome mutation targets the brain
...Michael Greenberg and colleagues tackled a central mystery of the disorder: why mutations in the MeCP2 gene specifically produce neural pathology. They also sought to understand why the pathology of RTT does not appear until well into infant development.
