A polymorphism in the 5′ region of coagulation factor VII gene (F7) caused by an inserted decanucleotide

We describe a polymorphism in the 5′ region of the coagulation factor VII (FVII) gene, originating from a decanucleotide (CCTATATCCT) insert present in the less frequent allele. This marker can be detected by restriction analysis of polymerase chain reaction products.
