Official Full Name
collagen, type I, alpha 2
This gene encodes the pro-alpha2 chain of type I collagen whose triple helix comprises two alpha1 chains and one alpha2;chain. Type I is a fibril-forming collagen found in most connective tissues and is abundant in bone, cornea, dermis;and tendon. Mutations in this gene are associated with osteogenesis imperfecta types I-IV, Ehlers-Danlos syndrome type;VIIB, recessive Ehlers-Danlos syndrome Classical type, idiopathic osteoporosis, and atypical Marfan syndrome. Symptoms;associated with mutations in this gene, however, tend to be less severe than mutations in the gene for the alpha1;chain of type I collagen (COL1A1) reflecting the different role of alpha2 chains in matrix integrity. Three;transcripts, resulting from the use of alternate polyadenylation signals, have been identified for this gene.
