Factor V Leiden [CO006300]

Related Information

Abstract See Activated Protein C Resistance and Factor V Leiden Mutation. The term "factor V Leiden" is often used interchangeably with activated protein C resistance, although they are not true synonyms. The factor V Leiden mutation causes the vast majority of cases of activated protein C resistance. Whether or not additional mutations other than factor V Leiden can cause clinically-significant activated protein C resistance is under continued investigation.
