CTGovID NA
Funding Agency NHLBI-TOPMed
Overview This study is part of the NHLBI Trans-Omics for Precision Medicine (TOPMed) Whole Genome Sequencing Program. OMB-SCD was designed to identify genetic factors that predispose SCD patients to develop specific end-organ complications and to experience more or less severe clinical courses.
Focus Areas 1. Whole Genome Sequencing
2. The relationship of clinical characteristics (Hb genotype, hematologic, cardiopulmonary, neurologic, renal, hepatobiliary, musculoskeletal/cutaneous, pain, biomarkers, hydroxyurea therapy) with survival
3. Identification of molecular phenotypes and biomarkers that may be useful targets for SCD treatment
4. The relationship of severity of organ damage on survival
Outcomes 1. The primary endpoint was death during the follow-up period.
2. Comorbidities associated with decreased survival
3. Contributors to early mortality among SCD patients
4. Specific targeted outcomes (overall disease severity as well as specific types of end organ damage)
