- CDD is a rare neurodevelopmental disorder linked to mutations in the CDKL5 gene, leading to symptoms like epilepsy, muscle weakness, and developmental delays.
- Researchers created a gene therapy vector, AAV9.Syn.hCDKL5, to deliver the CDKL5 gene to the brain, using a specific promoter to enhance gene expression.
- Studies in mice showed that injecting the vector directly into the cerebrospinal fluid improved distribution and resulted in biological activity, with successful functional improvements observed at higher doses.
