The Collaborative Health Studies Coordinating Center (CHSCC, Department of Biostatistics, University of Washington,) assists with genotype data cleaning, phenotype data organization and coordination of logistics and administration of the consortium. It also serves as an internal data repository for GENEVA and assists in cross-study phenotypic data harmonization. With guidance from the Steering Committee, NHGRI and the ESP, the CC provides leadership and management for administrative and scientific data management matters. While the SI are responsible for their own data analysis, the CC also provides statistical advice as needed.
