ABSTRACT
G20210A prothrombin mutation is one of the most prevalent mutations in the western countreis. In most diagnostic algorithms, G20210A prothrombin mutation's identification is the major tool in determining the cause of thrombosis. However, there is little evidence about the prevalence of this mutation in thrombophilia and its role among Asian and especially Iranian people. According to sporadic investigations there exist some evidence of the low prevalence rate of the mutation in Iranian patients. The case at issue has been negative in regard to other inherited and acquired causes; thus, the researchers intended to study the mutation rate in this case. The patient under study had the past record of recurrent miscarriage and CVA. Considering the limited number of studies conducted on thrombosis genetic prevalence and their impact on recurrent abortions and thrombophilia in Iran, this study is considered to be the first report on the screening of G20210A mutation. In this regard, the role of this mutation in unexplained miscarriage and exacerebation of underlying disorders could be investigated
