[[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> | <tr id='related'><td class="sblockLbl"><b>[[Related_structure|Related:]]</b></td><td class="sblockDat">[[1nq9|1nq9]], [[2b5t|2b5t]]</td></tr> | ||
