[The investigation of angiotensin converting enzyme I/D and plasminogen activator inhibitor-1 4G/5G polymorphisms in venous thromboembolism patients]. / Venöz tromboembolili hastalarda anjiyotensin dönüstürücü enzim I/D ve plazminojen aktivatör inhibitör-1 4G/5G gen polimorfizmlerinin arastirilmasi.

INTRODUCTION: Deep venous thrombosis and pulmonary embolism, known as venous thromboembolism and seen as a fairly common multifactorial diseases. Differ between populations due to genetic factors, several polymorphisms associated with venous thromboembolism was conducted. As a result of these studies the relationship between disease development and polymorphism is not clear yet. In this study we aimed to investigate the role of angiotensin converting enzyme insersion/deletion (ACE I/D) and plasminogen activator inhibitor-1 4G/5G (PAI-1 4G/5G) polymorphism in the development of disease. MATERIALS AND METHODS: In our study, DNA isolated from 80 venous thromboembolism patients and 79 control groups was used. While the classical polymerase chain reaction method used to investigate the ACE I/D polymorphism, the polymerase chain reaction based on allele-specific amplification was used for the detection of PAI-1 4G/5G polymorphism. RESULTS: As a result, there were no significant statistical differences for ACE I/D and PAI-1 4G/5G polymorphism among patient and control groups (p> 0.05). CONCLUSION: These findings revealed that there is no relationship between these polymorphisms and the development of venous thromboembolism, but large-scale studies are need to be done.
