Title: Identification of Prothrombin Belgrade Variant in a Mexican–American Family with Recurrent Deep Vein Thrombosis

Authors: Émile Moura Coelho da Silva, Natalie Montanez, Miguel Escobar

First Case of the Rare Prothrombin Belgrade Variant in a Mexican-American Family with VTE

We report the first case of the rare prothrombin Belgrade variant (c.1787G>A, p.Arg596Gln) in a Mexican-American family, associated with recurrent early-onset venous thromboembolism (VTE). This case highlights the potential underrecognition of antithrombin-resistant prothrombin variants and supports the value of comprehensive genetic thrombophilia testing in patients with negative standard hypercoagulable studies but a strong personal and/or family history of VTE.

Grateful to Dr. Miguel Escobar and Natalie Montanez for their support and collaboration!”
