| [[http://www.uniprot.org/uniprot/ANT3_HUMAN ANT3_HUMAN]] Defects in SERPINC1 are the cause of antithrombin III deficiency (AT3D) [MIM:[http://omim.org/entry/613118 613118]]. AT3D is an important risk factor for hereditary thrombophilia, a hemostatic disorder characterized by a tendency to recurrent thrombosis. AT3D is classified into 4 types. Type I: characterized by a 50% decrease in antigenic and functional levels. Type II: has defects affecting the thrombin-binding domain. Type III: alteration of the heparin-binding domain. Plasma AT-III antigen levels are normal in type II and III. Type IV: consists of miscellaneous group of unclassifiable mutations.<ref>PMID:7734359</ref> [:]<ref>PMID:3191114</ref> <ref>PMID:9031473</ref> <ref>PMID:6582486</ref> <ref>PMID:3080419</ref> <ref>PMID:3805013</ref> <ref>PMID:3179438</ref> <ref>PMID:3162733</ref> <ref>PMID:2781509</ref> <ref>PMID:2365065</ref> <ref>PMID:2229057</ref> <ref>PMID:2013320</ref> <ref>PMID:1906811</ref> <ref>PMID:1555650</ref> <ref>PMID:1547341</ref> <ref>PMID:8443391</ref> <ref>PMID:8486379</ref> <ref>PMID:7981186</ref> <ref>PMID:7959685</ref> <ref>PMID:8274732</ref> <ref>PMID:7994035</ref> <ref>PMID:7989582</ref> [:]<ref>PMID:7878627</ref> <ref>PMID:7832187</ref> <ref>PMID:9157604</ref> <ref>PMID:9845533</ref> <ref>PMID:9759613</ref> <ref>PMID:10997988</ref> <ref>PMID:11794707</ref> <ref>PMID:11713457</ref> <ref>PMID:12353073</ref> <ref>PMID:12595305</ref> <ref>PMID:12894857</ref> <ref>PMID:15164384</ref> <ref>PMID:16908819</ref>

| == Function ==
| |
| [[http://www.uniprot.org/uniprot/ANT3_HUMAN ANT3_HUMAN]] Most important serine protease inhibitor in plasma that regulates the blood coagulation cascade. AT-III inhibits thrombin, matriptase-3/TMPRSS7, as well as factors IXa, Xa and XIa. Its inhibitory activity is greatly enhanced in the presence of heparin.<ref>PMID:15853774</ref>
