The Factor V R2 DNA Test
The Factor V R2 DNA Test
Factor V Leiden is the most common genetic risk factor for venous thrombosis and pulmonary embolism, present in 5% of the Caucasian population and in 20-40% of individuals with a history of venous thromboembolism. Not all individuals who are heterozygous for factor V Leiden will experience a thrombotic event.
The presence of the R2 polymorphism in the factor V gene increases the likelihood of thrombosis in factor V Leiden heterozygotes. The R2 polymorphism is very common, occurring in 1 in 10 individuals. This polymorphism is part of the HR2 haplotype, a collection of polymorphisms always inherited together.
Indication for Testing:
Heterozygosity for factor V Leiden demonstrated by the Factor V Leiden DNA Test (the R2 DNA test is not indicated for factor V Leiden homozygotes)
