A NlaIII polymorphism within the human factor VII gene.

ABSTRACT

The polymorphism is located within exon 5 of the human coagulation factor VII gene and is silent at the amino acid level. The distribution pattern is similar in Caucasians and African Americans. This polymorphism may be useful for restriction fragment length polymorphism (RFLP) diagnosis of factor X deficiency as well as factor VII deficiency, since the factor X gene is closely linked to the factor VII locus.
