Identifying biomarkers in Rett Syndrome
Official title: Characterization of Translatable Neurophysiological Biomarkers to Enhance Therapeutic Development in Rett Syndrome
Run by Children's Hospital of Philadelphia · NCT05932589 · Data updated 2026-11-12
This study is trying to find specific brain signals in girls with Rett Syndrome to see how they differ from girls without the condition and how these signals relate to the severity of their symptoms over time.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include females aged 3-18 with a clinical diagnosis of RTT and a pathogenic variant in MECP2.
✕Probably not a fit
Patients with active medical conditions not typically found in RTT or those with duplications in MECP2 may not benefit from this study.

What this trial studies
This observational study aims to identify candidate biomarkers in individuals with Rett Syndrome (RTT) by measuring electrical activity in the brain through electroencephalograms (EEG) and evoked potentials. The study will compare findings from females with RTT to age-matched typically developing females to assess differences in neurophysiological parameters. Researchers will also explore the stability of these biomarkers over time and their correlation with clinical severity and disease staging. The ultimate goal is to establish reliable measures for future interventions and translational studies.
Why it matters
Potential benefit: If successful, this study could lead to the development of reliable biomarkers for monitoring disease progression and treatment efficacy in Rett Syndrome.
How similar studies have gone: Other studies have shown promise in identifying biomarkers for neurological disorders, but this specific approach in RTT is novel.

Inclusion Criteria: 1. Rett Group: Females ages 3-18 (inclusive) with a clinical diagnosis of RTT with a likely pathogenic or known pathogenic variant in MECP2. 2. Likely Rett Group: Females from 1 year to \< 5 years of age with MECP2 variant if regression has not yet occurred or child is within 6 months of last skill loss. 3. Typically developing (TD) Group: Females age matched to RTT population (1-18) with no developmental or cognitive concerns as assessed using the Child/Adult Behavioral Checklist, Survey of Well-Being of Young Children (\<5yo), or the Wide Range Achievement Test-4 (\>5 yo). Exclusion Criteria: Rett and Likely Rett Groups: 1. Presence of a duplication in MECP2 or any other identified pathogenic variant in another gene with a neurodevelopmental phenotype. 2. Active medical conditions not typically found in RTT. Typically Developing Group: 1. Score below norms on the performance tests 2. Have a known neurological disorder (excluding migraine) 3. Being on neuroactive medications.
