EDS is a connective tissue disorder characterized by hyperextensible skin, atrophic cutaneous scars due to tissue fragility and joint hyperlaxity. EDS3 is a form of Ehlers-Danlos syndrome characterized by marked joint hyperextensibility without skeletal deformity.<ref>PMID:7833919</ref> Defects in COL3A1 are the cause of Ehlers-Danlos syndrome type 4 (EDS4) [MIM:[http://omim.org/entry/130050 130050]]. EDS is a connective tissue disorder characterized by hyperextensible skin, atrophic cutaneous scars due to tissue fragility and joint hyperlaxity. EDS4 is the most severe form of the disease. It is characterized by the joint and dermal manifestations as in other forms of the syndrome, characteristic facial features (acrogeria) in most patients, and by proneness to spontaneous rupture of bowel and large arteries. The vascular complications may affect all anatomical areas.<ref>PMID:1370809</ref> <ref>PMID:8411057</ref> <ref>PMID:2492273</ref> <ref>PMID:7749417</ref> <ref>PMID:1352273</ref> <ref>PMID:2808425</ref> <ref>PMID:1895316</ref> <ref>PMID:1357232</ref> <ref>PMID:1496983</ref> <ref>PMID:8098182</ref> [:]<ref>PMID:7912131</ref> <ref>PMID:8019562</ref> [:]<ref>PMID:8680408</ref> <ref>PMID:8884076</ref> <ref>PMID:9147870</ref> <ref>PMID:8664902</ref> <ref>PMID:8990011</ref> <ref>PMID:9036918</ref> <ref>PMID:9452103</ref> <ref>PMID:10923041</ref> <ref>PMID:10706896</ref> <ref>PMID:11168790</ref> <ref>PMID:12694234</ref> <ref>PMID:12786757</ref> Defects in COL3A1 are a cause of susceptibility to aortic aneurysm abdominal (AAA) [MIM:[http://omim.org/entry/100070 100070]]. AAA is a common multifactorial disorder characterized by permanent dilation of the abdominal aorta, usually due to degenerative changes in the aortic wall. Histologically, AAA is characterized by signs of chronic inflammation, destructive remodeling of the extracellular matrix, and depletion of vascular smooth muscle cells.<ref>PMID:8514866</ref> <ref>PMID:2243125</ref> <ref>PMID:2349939</ref> | ||

+ | The C propeptides of fibrillar procollagens have crucial roles in tissue growth and repair by controlling both the intracellular assembly of procollagen molecules and the extracellular assembly of collagen fibrils. Mutations in C propeptides are associated with several, often lethal, genetic disorders affecting bone, cartilage, blood vessels and skin. Here we report the crystal structure of a C-propeptide domain from human procollagen III. It reveals an exquisite structural mechanism of chain recognition during intracellular trimerization of the procollagen molecule. It also gives insights into why some types of collagen consist of three identical polypeptide chains, whereas others do not. Finally, the data show striking correlations between the sites of numerous disease-related mutations in different C-propeptide domains and the degree of phenotype severity. The results have broad implications for understanding genetic disorders of connective tissues and designing new therapeutic strategies. | ||
