Molecular genetic testing of polymorphisms associated with venous thrombosis: a review of molecular technologies

The growing knowledge of genetic polymorphisms predisposing to venous thrombosis has increased the demand for genetic testing of associated risk factors. This has prompted the need for simple, fast, reliable, and cost-effective genotyping methods for identification of those mutations. In the past decade, a large variety of DNA mutation analysis methods have been developed for detection of genetic variants associated with venous thrombosis, including PCR-based and PCR-independent technologies. Each of these technologies possesses unique advantages, but all have a common goal of simplifying and expediting mutation analysis. This review describes some of the commonly used technologies and commercially available platforms employed in clinical laboratories for genetic testing of thrombophilia. The choice of a technology for each individual laboratory would primarily depend on the specific requirements for the assay's accuracy, reliability, speed, throughput, and cost-effectiveness.
