Hypoplasminogenemia

Plasminogen deficiency is an autosomal recessive disorder caused by mutations of the PLG gene. It is characterized by low levels or dysfunctional plasminogen.As plansmin is the enzyme responsible for fibrinolysis. a deficiency results in thrombophilia. In type 1 deficiency also wound healing is impaired.

Classification

Two types of mutations can be distinguished. With type 1 the protein is completely absent in plasma. With type two the antigen is present but dysfuntional. In type 2 deficiency wound healing is not impaired.
