摘要:

假性软骨发育不全(pseudoachondroplasia, PSACH)和多发性骨骺发育不良(multiple epiphyseal dysplasia, MED)均为骨发育不良性疾病的家族成员之一, 它们的遗传方式和临床表型都具有异质性的特点, 二者均由软骨低聚物基质蛋白(cartilage oligomeric matrix protein, COMP)基因突变所致。COMP是血小板凝血酶敏感蛋白(thrombospondin, TSP)家族的成员之一, 它在骨骼的发育过程中起着重要的作用, 文章着重就COMP的结构与功能、COMP基因的突变类型、检测方法及其与两病的相关性的最新进展作一综述。

Abstract:

Pseudoachondroplasia (PSACH) and multiple epiphyseal dysplasia (MED) belong to the family of bone dysplasia disorders, which are both genetically and phenotypically heterogeneous. Both disorders are caused by mutations in the cartilage oligomeric matrix protein (COMP). COMP is a member of the thrombospondin (TSP) family, which plays an important role in skeletal development. In this paper, we mainly review the latest advances on the structure, function of COMP. We also discuss the types of COMP mutations, the detection methods and the relationship between the COMP gene and these two diseases.
