Protein C deficiency is a rare genetic trait that predisposes to thrombotic disease. [83] Protein S deficiency: Factor V Leiden: Thrombocytosis: Idiopathic thrombocytopenic purpura: D69.3: 6673: D016553 Idiopathic thrombocytopenic purpura (ITP) is the condition of having a low platelet count (thrombocytopenia) of no known cause .

Factor V Leiden is an inherited blood clotting disorder. It can cause life-threatening clots in the body and complications during pregnancy.
APC resistance is the inability of protein C to cleave Factor Va and/or Factor VIIIa, which allows for longer duration of thrombin generation and may lead to a hypercoagulable state. This may be hereditary or acquired. [4] The best known and most common hereditary form is Factor V Leiden, which is responsible for more than 95% of cases. [5]
The activated protein C resistance (APCR) test is a coagulation test used in the evaluation and diagnosis of activated protein C (APC) resistance, a form of hypercoagulability.
The exact prevalence of protein S deficiency in the population is unknown; it is found 1.3–5% of people with thrombosis. [14] The minor ("type 2") thrombophilias are much more common. Factor V Leiden is present in 5% of the population of Northern European descent, but much rarer in those of Asian or African extraction.
There have also been cases in patients with other deficiency, including protein S deficiency, [6] [7] activated protein C resistance (Factor V Leiden) [8] and antithrombin III deficiency. [ 9 ] Although the above hypothesis is the most commonly accepted, others believe that it is a hypersensitivity reaction or a direct toxic effect.
