Gene Doping Workshop in Japan

Chaired by Teruaki Tozaki, Ph.D.

Organized by the Genetic Analysis Department, Laboratory of Racing Chemistry, Japan

Supported by the IFHA Gene Doping Control Subcommittee, the AORC Gene Doping ad-hoc committee, and the ISBC

Day: September 26 and 27, 2019

Venue: Utsunomiya Tobu Hotel Grande


The development of veterinary sciences contributes to the health and welfare of racehorse, but also may create concerns of genetic doping as a new threat. In 2017, the Gene Doping Control Subcommittee was established at the IFHA to discuss the definition of gene therapy in the horse racing industry and the genetic doping for its misuse. In the AORC and ISBC, special committees were also established with discussion of genetic doping and genetically modified racehorse concerns.

Workshop Principles

  • Participants understand what genetic doping is and experience its detection method.
  • Look at the genetic laboratory and experience actual gene doping detection. Participants understand which types of analysts and which instruments are required for gene doping detection.
  • Success by any one of us is success for racing industries and all of us. Developing gene doping testing methods is a large undertaking. Therefore, cooperative and collaborative activities are essential to accomplish our goals.
