Registry for patients with Congenital Dyserythropoietic Anemia

The Congenital Dyserythropoietic Anemia Registry (CDAR)

Observational Children's Hospital Medical Center, Cincinnati · NCT02964494

This study is collecting information from people with Congenital Dyserythropoietic Anemia to help researchers learn more about the condition and improve care for those affected.

What this trial studies

This registry collects long-term data on patients diagnosed with Congenital Dyserythropoietic Anemia (CDA) across North America, including the US, Canada, and Mexico. It aims to maintain a bio-repository of de-identified blood and bone marrow specimens to facilitate research into the epidemiology, natural history, and molecular mechanisms of CDA. The registry is designed to enhance understanding of this rare group of genetic disorders characterized by ineffective erythropoiesis and to promote collaboration among affected individuals and their healthcare providers.

Who should consider this trial

Good fit: Ideal candidates include individuals of all ages diagnosed with any type of Congenital Dyserythropoietic Anemia, regardless of whether a genetic mutation has been identified.

Not a fit: Patients with cancer, myelodysplasia, or secondary dyserythropoiesis are unlikely to benefit from this registry.

Why it matters

Potential benefit: If successful, this registry could lead to improved understanding and management of Congenital Dyserythropoietic Anemia, ultimately enhancing patient care.

How similar studies have performed: While this registry approach is relatively novel for CDA, similar registries for other rare diseases have shown success in advancing research and understanding.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Diagnosis of Congenital Dyserythropoietic Anemia (CDA), whether a genetic mutation is identified or not
* Evidence of congenital anemia/jaundice or a positive family history
* Evidence of ineffective erythropoiesis
* Typical morphological appearance of bone marrow erythroblasts
* All ages (ages 0-99)

Exclusion Criteria:

* Diagnosis of cancer
* Myelodysplasia
* Secondary dyserythropoiesis: e.g.; vitamin B12 deficiency or drug-related.

Note1: Patients with rare band 3 (SLC4A1) mutations recently described to be associated with dyserythropoiesis will be eligible since the mechanisms appear to involve direct participation of band 3 in the erythroblast mitosis and cytokinesis.

Note2: Siblings, parents, and family members of patients with confirmed CDA diagnosis are encouraged to participate in the study.
