Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include children and adults with rare diseases whose molecular mechanisms are not fully understood and who are part of the BaMaRa database.
✕Probably not a fit
Patients with well-characterized rare diseases or those whose molecular functions are already known 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
This study utilizes next generation sequencing (NGS) to identify genetic variants associated with rare diseases that are not yet fully understood. By collecting biological samples such as skin biopsies, blood, and urine, the study aims to confirm the relationship between these genetic variants and the clinical manifestations of the diseases. The research focuses on patients whose molecular functions are unknown, contributing to a better understanding of rare genetic conditions. The findings could lead to improved diagnostics and potential therapeutic strategies for affected individuals.
Why it matters
Potential benefit: If successful, this study could enhance the understanding and diagnosis of rare genetic diseases, leading to better patient management.
How similar studies have gone: Other studies utilizing next generation sequencing for rare diseases have shown promise, indicating that this approach is both relevant and potentially effective.
