Full Program


  • The CTC (Complex Trait Consortium) is open to all those interested in or working on the identification of gene networks and allelic variants that modulate complex phenotypes in diverse environments (geneticists, molecular biologists, bioinformaticists, statisticians, modelers, computer scientists, etc.). Along with the major large-scale genomic sequencing projects, QTL mapping, quantitative and systems genetics have undergone a major revolution in the last decade. Progress in the next decade promises to be even more rapid and the prospects for exploring and investigating the complex interactions between gene variants, disease, and the environment will be significantly improved. Essentially all human diseases are complex since their range of prevalence, severity and outcome is determined by the interaction of many genes and environmental factors. Representative areas of interest at the annual meeting include statistical and computational tools, complex trait resources, use of humans and model organisms for complex or polygenic trait analysis, systems genetics, genetical genomics, population genetic variation associated with phenotypic variation, and QTLs. There will be cash prizes for best student and postdoc presentations (both platform talks and posters).


  • David A. Schwartz, director of National Institute of Environmental Health Sciences (NIEHS).
  • Jean-Louis Guenet, Institute Pasteur.


  • Online registration form is available here
    After registering, you will be directed to a secure site to pay the registration fee ($125). Registration covers all meeting expenses, including a reception dinner on May 6th, breakfast and lunch on May 7th and 8th, and breakfast, lunch and the conference banquet on May 9th.
