Current Status of Developmental Encephalopathies: Rett Syndrome, MECP2 Duplication Disorder, CDKL5 Deficiency Disorder, and FOXG1 Disorder

Course Description

• To understand the recent advances in the developmental encephalopathies, namely, Rett syndrome, MECP2 Duplication Disorder, CDKL5 Deficiency Disorder and FOXG1 Disorder through comparison of the important similarities and critical differentiating features of this expanding group of neurodevelopmental disorders;
• To understand the phenotypegenotype relationships that characterize each disorder; and
• To promote the existing and emerging clinical trials that offer the potential for diseasemodifying or curative promise.

Learning Objectives

1. Understand the recent advances in the developmental encephalopathies, namely, Rett syndrome, MECP2 Duplication Disorder, CDKL5 Deficiency Disorder and FOXG1 Disorder through comparison of the important similarities and critical differentiating features of this expanding group of neurodevelopmental disorders including clinical trajectories and phenotype-genotype correlations.
2. Understand the current strategies and challenges to develop and promote clinical trials that offer the potential for disease-modifying or curative therapeutics. Impact Statements This educational session helped me to identify changes I could make in my practice related to:
3. Evaluation, diagnosis, and management of these developmental encephalopathies including directing these children to clinical centers focusing on these disorders.
4. Educating and advocating for parents and other caregivers regarding the therapeutic opportunities available or under development for these developmental encephalopathies.
