Funding Agency NHLBI-TOPMed
Grant Number 5R01HL079912-02
Overview This study is part of the NHLBI Trans-Omics for Precision Medicine (TOPMed) Whole Genome Sequencing Program. The study will look at the risk factors for pulmonary hypertension (high blood pressure in the lungs) in children and adolescents with sickle cell anemia (SCA) and examine the role of hypoxia (oxygen shortage) in the disease.
Focus Areas 1. Whole Genome Sequencing
2. 6-Minute Walk
3. Sickle Cell Anemia
4. Pulmonary Function Tests
5. Sickle Cell Disease
6. Pulmonary Hypertension
7. Chuvash Polycythemia
8. Echocardiogram
Outcomes Clinical factors associated with patient-reported history of one or more acute pulmonary events, either acute chest syndrome (ACS) or pneumonia, in patients with SCD.
