Antithrombin III is the most important inhibitor of coagulation proteinases such as thrombin and factor Xa. Inherited deficiency of antithrombin III is a well recognised risk factor for the early development of venous thromboembolism. The gene for antithrombin III is located at chromosome 1q 23-25 and its structural organisation has been described. A database of mutations of the antithrombin III gene has been compiled and a recent update lists 184 entries. These entries are listed according to subtype of deficiency and to nucleotide sequence number. There are 68 reports of type I 'classical' and 116 reports of type II 'variant' deficiencies. This summary considers the entries in terms of the number of unique molecular events, the nature of the genetic defects and the role of CpG dinucleotides in deficiency. Sample listings of type I and II deficiency entries are provided.
抗凝血酶III是凝血蛋白酶(如凝血酶和Xa因子)最重要的抑制剂。遗传性抗凝血酶III缺乏是静脉血栓栓塞早期发展的一个公认危险因素。抗凝血酶III基因位于1号染色体q23-25,其结构组织已被描述。已编制了抗凝血酶III基因突变数据库,最近的一次更新列出了184条记录。这些记录根据缺乏亚型和核苷酸序列号列出。有68份I型“经典”缺乏报告和116份II型“变异”缺乏报告。本综述从独特分子事件的数量、遗传缺陷的性质以及CpG二核苷酸在缺乏中的作用等方面考虑这些记录。提供了I型和II型缺乏记录的样本列表。
