Rett Syndrome Treatment Breakthrough by Texas Children's

Researchers at Texas Children s Hospital and Baylor College of Medicine have discovered a potential new therapeutic approach for Rett syndrome, a rare neurodevelopmental disorder primarily affecting girls. The study, published in Science Translational Medicine, demonstrates that modulating the alternative splicing of the MECP2 gene to increase the production of the MeCP2-E1 protein can alleviate symptoms in mouse models and patient-derived cells. This strategy aims to restore functional MeCP2 protein levels, which are disrupted by mutations in the MECP2 gene, without causing the toxicity associated with MeCP2 overexpression. Led by Huda Zoghbi and Harini Tirumala, the team's findings provide preclinical evidence for developing antisense oligonucleotide therapies, offering hope for a condition that currently lacks a cure.
