GTR Home > Conditions/Phenotypes > Thrombophilia, hereditary, due to protein C deficiency, autosomal dominant

Summary

Heterozygous protein C deficiency is characterized by recurrent venous thrombosis. However, many adults with heterozygous disease may be asymptomatic (Millar et al., 2000). Individuals with decreased amounts of protein C are classically referred to as having type I deficiency and those with normal amounts of a functionally defective protein as having type II deficiency (Bertina et al., 1984). Acquired protein C deficiency is a clinically similar disorder caused by development of an antibody against protein C. Clouse and Comp (1986) reviewed the structural and functional properties of protein C and discussed both hereditary and acquired deficiency of protein C. [from OMIM]
