Researchers developed a mouse model for Rett Syndrome (RTT), a neurodevelopmental disorder resulting from a mutation in the X-linked protein MECP2, in which the mice exhibit short lifespans, neuromotor impairment, and repetitive behaviors observed in RTT; the researchers demonstrated a correlation between MECP2 levels and amelioration of the RTT phenotype, finding that 5-10% of MECP2 restoration is associated with improved neuromotor function and extended lifespan in mice, findings with therapeutic implications for RTT.
