Polymorphism Description:  This polymorphism is due to G->A substitution at nucleotide position 1691 in exon 10 (11 nucleotides 5 of the start of intron 10)of the gene.This missense mutation predicts the replacement of Arg506(CGA) by Gln (CAA) in one of the cleavage sites for activated protein C.This mutation is known as factor V Leiden (FVL) mutation.This mutation has been known to be associated with resistance to degradation by activated protein C, a functional abnormality of homeostatis associated with increased risk of venous thromboembolism.(PMID :7877648)
