  • A Genome-Wide Association Study of Bisphosphonate-Associated Atypical Femoral Fracture. - Calcified tissue international (2020) · Kharazmi M, Michaëlsson K, Schilcher J, Eriksson N, Melhus H, Wadelius M, Hallberg P · PubMed 31006051

    Atypical femoral fracture is a well-documented adverse reaction to bisphosphonates. It is strongly related to duration of bisphosphonate use, and the risk declines rapidly after drug withdrawal. The mechanism behind bisphosphonate-associated atypical femoral fracture is unclear, but a genetic predisposition has been suggested. With the aim to identify common genetic variants that could be used for preemptive genetic testing, we performed a genome-wide association study. Cases were recruited mainly through reports of adverse drug reactions sent to the Swedish Medical Products Agency on a nation-wide basis. We compared atypical femoral fracture cases (n = 51) with population-based controls (n = 4891), and to reduce the possibility of confounding by indication, we also compared with b
