Is this trial a fit for you?

Likely a good fit

Ideal candidates are individuals aged 5–50 with a confirmed 7q11.23 microduplication and French-speaking mothers as part of a health-insured family.

Probably not a fit

Patients without a 7q11.23 microduplication or those not meeting language/consent criteria may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Participants with a confirmed 7q11.23 microduplication will undergo clinical assessments, parental questionnaires, cognitive, reasoning, and motor testing to characterize the natural history of 7DUP and related neurodevelopmental issues. Each participant will be paired with sex- and age-matched controls drawn from the CREAT_criteria study data. The study will be conducted at multiple Lyon centers under a centralized lead sponsor to standardize data collection. Enrollment requires French-speaking mothers/guardians and health-insurance affiliation, with informed consent obtained from participants or guardians. The goal is to better understand social and cognitive profiles and identify patterns that could inform future interventions.

Why it matters

Potential benefit: Findings may improve understanding of 7DUP and help guide future care and monitoring for affected individuals.

How similar studies have gone: Previous work has established genetic and neurodevelopmental links for 7DUP; this study builds on that by characterizing natural history with matched controls.
