Genetic predisposition to cancer

​Description of Research

The group is studying both breast and prostate cancer genetics, the main goal being on prostate cancer. Of all cancers, prostate cancer (PrCa) has been reported as one of the most heritable diseases. Genetic factors were recently estimated to account for 58% of the risk, using data from the Nordic Twin Study of Cancer. However, genetics has proven challenging because of the very heterogeneous nature of the disease. Our goal is to identify and characterize predisposing genes and variants, especially those affecting aggressive outcome, including treatment response to therapies.  This data will have diagnostic utility at an early, curable stage of the disease. Further, the aim is to develop tools for prognostic purposes, i.e. prognostic biomarkers, which are urgently needed in PrCa screening and clinical practice. In our previous work we have identified significant genomic regions, candidate genes and variants, which are further profiled and characterized.
