Is this trial a fit for you?

Likely a good fit

Ideal candidates include individuals with a known or suspected diagnosis of CAGS and a relevant genetic variant in ANKRD17.

Probably not a fit

Patients without evidence of a disease-causing or potentially disease-causing ANKRD17 variant will 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

This observational study aims to create a registry for individuals with confirmed or suspected Chopra-Amiel-Gordon Syndrome (CAGS) to explore the range of symptoms, brain imaging changes, and learning difficulties associated with the disorder. Participants will provide medical and family histories, MRI records, photographs, and genetic test results, with a subset undergoing standardized neurobehavioral assessments. The collected data will be securely maintained for further analysis, and sample collection for functional testing and neuronal reprogramming will be offered to participants.

Why it matters

Potential benefit: If successful, this study could enhance understanding of CAGS, leading to better diagnosis and management strategies for affected individuals.

How similar studies have gone: While this study builds on previous findings regarding CAGS, it employs a novel approach by incorporating standardized assessments to validate earlier observations.

Inclusion Criteria:

* Participants must have a variant in ANKRD17 with a classification of VUS, likely pathogenic, or pathogenic
* Participants with a known diagnosis or CAGS have a disease-causing (likely pathogenic or pathogenic) variant in ANKRD17 evidenced by a pre-existing clinical genetic report.
* Participants with a suspected diagnosis of CAGS must have a variant of uncertain significance in ANKRD17 evidenced by a pre-existing clinical genetic report and clinical features of CAGS
