The Wellcome Trust Case Control Consortium (abbreviated WTCCC) is a collaboration between fifty research groups in the United Kingdom in the field of human genetics.
Established in 2005, the WTCCC aims to conduct genome-wide association studies (GWASs) to shed light on the genetic architecture of common human diseases.
[1] The founding chairman of the consortium was University of Oxford statistician Peter Donnelly.
[2] According to the consortium's website, it has identified "approximately 90" new susceptibility loci for common human diseases.
These GWASs included a total of 19,000 subjects, of whom 2,000 had one of the eight diseases and an additional 3,000 served as controls.
