At the end of the Fifth Santorini Conference (October 2010) in conclusion of the round table it was decided to think about the interest of having a scientific European organization able to give advice on the existing new field of pharmacogenomics. The purpose was to check the quality of the different information existing on the websites and to develop education and scientific aspects of pharmacogenomics and theranostics. A board of 6 members: Gérard Siest, Ron H.N. Van Schaik, Vangelis G. Manolopoulos, George Patrinos, Adriano Henney and Adrian Llerena has been set up and statutes under Greek law were elaborated and accepted at the first ESPT meeting and general assembly in October 2011 in Bled, Slovenia. A website (www.esptnet.eu) was also implemented.
