A Breast Cancer Polygenic Risk Score Is Feasible for Risk Stratification in the Norwegian Population Akdeniz, Bayram Cevdet; Mattingsdal, Morten; Dominguez-Valentin, Mev; Frei, Oleksandr; Shadrin, Alexey; Puustusmaa, Mikk; Saar, Regina; Sõber, Siim; Møller, Pål; Andreassen, Ole; Padrik, Peeter; Hovig, Eivind (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Background: Statistical associations of numerous single nucleotide polymorphisms with breast cancer (BC) have been identified in genome-wide association studies (GWAS). Recent evidence suggests that a Polygenic Risk Score ...
