The GENEVA study structure promotes collaborative efforts and ongoing interactions among all participating studies. Since the initiation of GENEVA, various subcommittees and working groups have been established to address specific issues related to analysis, genotyping QC and assurance, phenotype harmonization, cross-study integration and other challenges inherent to collaborative studies. Through monthly teleconferences and in-person Steering Committee meetings held three times per year, this interacting network of teams has been crucial in addressing the consortium’s aims.
