In 2018, deCODE launched a website that enables Icelanders to request the analysis of their sequence data to determine whether they carry a SNP in the BRCA2 gene linked to significantly increased risk of breast and prostate cancer in Icelanders.  This was the first time that deCODE, which is primarily a research organization, returned information from its research data to participants. Stefansson had tried for many years to convince the Icelandic Ministry of Health that this was a serious public health issue that deCODE's data could address at virtually no cost, and it was but one of the clearest-cut of many such possible precision medicine applications to healthcare in Iceland.
