Rett Syndrome: Coming to Terms with Treatment
Table 6
Rett Syndrome (therapeutic options).
| MeCP2 restoration | Missense mutations: reactivate full-length protein | | Nonsense (stop) mutations: promote full-length protein; may require “reactivation” | | Deletions/insertions: more complicated | |
| Symptomatic therapy | Serotonin reuptake inhibitors: ameliorate anxiety | | NMDA receptor blocker: memantine reverse glutamate hyperexcitability | | IGF-1: full length and tri-peptide downstream effect in BDNF cascade | | BDNF-mimetics: TrkB agonists restore BDNF levels | | Read-through compounds: stop mutations produce full length MeCP2 | |
| Gene therapy | Gene correction correct only abnormal allele | | Stem cell transplant | | X chromosome activation of normal allele activate normal allele in all cells | |
