Blood donation

The primary study objective is to collect biospecimen samples (e.g., blood) from participants diagnosed with Fanconi Anemia. The biospecimens will be used to create a biorepository that can be used to identify disease associated biomarkers and potential targets with immune and multi-omics profiling. The disease sample collection and analysis will be the foundation for an extensive network of biospecimen access and linked datasets for future translational research.
