Protein Deficiencies

A deficiency is something that fails to meet a particular need or requirement, usually due to a lack or shortage, functional quality or availability.

There are many health conditions caused by a deficiency of essential substances such as vitamins, minerals, hormones and proteins.

Protein Deficiency

Factor XII (Hageman factor) Deficiency

Factor XII deficiency is a rare hereditary disorder with no symptoms. It does not cause abnormal bleeding in the affected person but the blood takes longer than normal to clot (coagulate) in a test tube. (www)

Protein C Deficiency

A deficiency of the anticoagulant protein C, is associated with a variably increased risk of thrombosis. In the rare inherited homozygous or compound heterozygous state, protein C deficiency is associated with severe life-threatening neonatal purpura fulminans or massive venous thrombosis. The inherited heterozygous state of protein C deficiency most frequently is associated with deep venous thrombosis of the lower limb but also may manifest in other venous locations. A significant percentage of patients with protein C deficiency remain asymptomatic. (www)

Protein S Deficiency

Protein S Deficiency (PSD) is a rare blood disorder that affects just a few thousand people worldwide. It is one of several known risk factors for thrombophilia and can increase the risk of blood clots such as Deep Vein Thrombosis (DVT) and Pulmonary Embolism (PE). (www)
