Gene Editing as a Therapeutic Approach for Rett Syndrome

Inclusion Criteria:

* Patients -exclusively female- since the pathology is linked to the X chromosome, with a clinical diagnosis of Rett syndrome confirmed at the genetic level by the identification, through NGS analysis, for one of the recurrent mutations (mutational hotspots) in the MECP2 gene object of the study:

  c. 473C\>T - (p.(T158M)), c.502C\>T (p(R168X)), c.763C\>T (p.(R255X)), c.916C\>T (p.(R306C));
* Age above 6 months;
* Availability of parents or legal guardians to provide free and informed consent to participate in the study

Exclusion Criteria:

* NGS diagnosis with the normal outcome;
* Positive NGS diagnosis for mutation in MECP2 but with the presence of a mutation different from those under study.
* Unwillingness of parents or legal guardians to provide free and informed consent to participate in the study;
