Brief Summary:
the investigators hypothesize that some of these polymorphisms contribute to VTE risk in women using COC, and that their screening could to help assess individual risk of VTE before COC prescription.
In order to test this hypothesis the investigators propose to build a predictive score for VTE in women using COC based on clinical and biological factors. To this end the investigators have a large case study (including 766 patients) recruited at the "Centre d'Exploration des Pathologies Hémorragiques et Thrombotiques" (CEHT) of the laboratory of Hematology (La Timone Hospital, Marseille) between 2003 and 2013. The cases had a personal history of documented VTE while using COC (PILGRIM study). A great number of clinical and biological relevant phenotypes in the field of VTE have already been collected (including 14 polymorphisms selected on the basis of their biological plausibility and the existence association studies).To our knowledge it is the largest study specifically conducted in order to assess genetic factors associated with VTE in women using COC. These 766 cases will be compared to 766 controls from the general population (cohort Nutrinet-Santé). Then, the predictive values of the score will be assessed in an independent multicentric validation study that the investigators will set up in the field of this project. Our study should allow a better understanding of the genetic and environmental factors involved in VTE related to COC use. Besides, this project aims to respond to a major public health issue giving an effective tool for the decision of prescribing COC.
