iCOGS collection provides a collaborative model

Nature Genetics is pleased to present the iCOGS Focus comprising a collection of 13 papers from COGS, representing a significant advance in our understanding of genetic susceptibility to three hormone-related cancers: breast, ovarian and prostate cancer. We hope that you will find this Focus issue, as well as the accompanying Focus online, a useful guide to this milestone in genetic epidemiology.
