Autosomal recessive protein C deficiency is an inherited blood clotting disorder characterized by serious protein C deficiency. The disease may be very severe and associated with neonatal purpura fulminans (NPF) or intracranial thromboembolism. It may also be a milder disorder where patients present with clotting (venous thromboembolism) in childhood, adolescence, or adulthood. It is caused by having changes in the PROC gene. The inheritance pattern is autosomal recessive. Treatment depends on the severity of the disease and may involve blood thinners, clot-dissolving medicines, or blood transfusions of fresh frozen plasma or highly purified protein C concentrate. In some cases, live donor liver transplantation which cures the disease.
