Type I collagen is the most abundant and ubiquitously distributed of the collagen family of proteins. It is a heterotrimer comprising two alpha1(I) chains and one alpha2(I) chain which are encoded by the unlinked loci COL1A1 and COL1A2 respectively. Mutations at these loci result primarily in the connective tissue disorders osteogenesis imperfecta and Ehlers-Danlos syndrome types VIIA and VIIB. Two instances of osteoporosis and a single instance of Marfan syndrome are also the result of mutations at these loci. The mutation data are accessible on the world wide web at http://www.le.ac.uk/depts/ge/collagen/collagen.html
I型胶原蛋白是胶原蛋白家族中含量最丰富且分布最广泛的蛋白质。它是一种异源三聚体,由两条α1(I)链和一条α2(I)链组成,这两条链分别由不连锁的基因座COL1A1和COL1A2编码。这些基因座的突变主要导致结缔组织疾病成骨不全以及VIIA和VIIB型埃勒斯-当洛综合征。两例骨质疏松症和一例马凡综合征也是这些基因座突变的结果。突变数据可在万维网上的http://www.le.ac.uk/depts/ge/collagen/collagen.html获取。
