Brain Gene Registry

Johns Hopkins IRB Protocol Number: IRB00343853
Site Principal Investigator: Constance Smith-Hicks, MD PhD
Status: Active, recruiting

The goals of this multi-site research study are to create a mechanism to interpret clinical genomic information in patients with IDD by establishing a national EHR-based IDD registry equipped to enhance phenotypic characterization, link genotypic and phenotypic data, and promote discovery. The research is supported by the IDDRS-CTSA Brain Gene Registry grant, U01TR002764 from NCATS/NIH.

Rett Syndrome Registry

Johns Hopkins IRB Protocol Number: IRB00321726
Site Principal Investigator: Constance Smith-Hicks, MD PhD
Status: Active, recruiting

This is a longitudinal multi-site study focused on the collection of real-world data from individuals with mutations on the MECP2 gene to better define the disease spectrum and the disease course throughout the lifespan, with the goal to improve care and accelerate drug development. This study is funded by the International Rett Syndrome Foundation. Learn more.

Sleep dysfunction in neurodevelopmental disorders of synaptic origin.

Johns Hopkins IRB Protocol Number: IRB00370853
Principal Investigator: Constance Smith-Hicks, MD PhD
Status: Active, recruiting

Sleep disorders are a common feature of neurodevelopmental disorders. In this clinical research study, we will use previously acquired overnight EEGs to examine neural networks underlying sleep and their association with behavioral features of synaptic disorders.

Examining phenotypic diversity in SYNGAP1-Related Disorders

This is a collaborative project with Lena Smirnova, PhD. We will use patient derived iPSC lines and brain organoids to examine neural mechanism involved in phenotype diversity. This research study is funded by a grant from the Maryland Stem Cell Research Fund.

Johns Hopkins IRB Protocol Number: NA_00028362
Principal Investigator: Dejan Budimirovic, MD
Status: Active, recruiting

The goal of this multi-site collaborate is to use Longitudinal Data to Characterize the Natural History of Fragile X Syndrome.
