Description:
The COL1A1 gene encodes the pro-alpha1 chains of type I collagen. Collagen is a major structural protein in the extracellular matrix and connective tissue, and comprises a family of 28 members. Type I collagen is the main collagen of skin, tendon and bone and by far the most common. Type I collagen molecules are triplet helical structures made up of two α1(I) and one α2(I) chains. These are synthesized as precursor proα1(I) and proα2(I) chains containing a repeating Gly-Pro-X sequence, and undergo a series of posttranslational modification steps prior to folding into a triple helix. Functional collagen molecules undergo fibrillogenesis. Mutations in this gene are associated with osteogenesis imperfecta types I-IV, Ehlers-Danlos syndrome type VIIA, Ehlers-Danlos syndrome Classical type, Caffey Disease and idiopathic osteoporosis. Polymorphisms in this gene associated with bone mineral density (osteoporosis) in β-thalassemia patients. Two transcripts, resulting from the use of alternate polyadenylation signals, have been identified for this gene.
