title: Genetic susceptibility to VTE: a primary care approach.
abstract: Genetic thrombophilic disorders are variably common and primary care clinicians must be aware of them because of the increased risk of VTE. A physical examination will not be able to determine if a given VTE resulted from a genetic predisposition or not. In some instances, a patient's personal and family history will alert a clinician to the existence of a thrombophilic disorder, but diagnosis of the specific thrombophilia will require laboratory evaluation and referral to a specialist. The acute management of VTE is the same regardless of the presence of a genetic thrombophilia; therefore, laboratory testing or evaluation by a specialist is not cause to delay treatment of the acute thrombotic event. After the initial treatment and stabilization of the patient, ample time exists to perform a thrombophilia workup. Long-term management of thrombophilia disorders is complicated and needs to be individualized, so referral to specialists is necessary. Primary care clinicians need to keep abreast of the studies being conducted on thrombophilia because numerous families continue to be plagued by VTEs without a recognizable cause. Undoubtedly, new causes of inherited thrombophilias are yet to be unveiled.
