The COGS project

COGS is a European Commission funded project with the overall objectives a) to determine the genetic determinants of breast, ovarian and prostate cancer, b) to assess gene and environment interaction, c) to assess inheritance of prognosis, d) to develop risk models to allow prediction of breast, ovarian and prostate cancer and e) to assess the organizational, ethical, legal and social implications of preventive initiatives.

COGS stands for "The Collaborative Oncological Gene-environment Study"

By 2012, more than 250,000 individuals had been genotyped using the 200,000 SNPs iCOGS chip, and the first major publications emerged in March 2013.

Financing: EU
