NCIt definition : Human COL1A1 wild-type allele is located in the vicinity of 17q21.33 and is approximately
18 kb in length. This allele, which encodes collagen alpha-1 (I) chain protein, is
involved in both the development and maintenance of tendon, ligaments and bones. Mutations
in the gene are associated with both Ehlers-Danlos syndrome and osteogenesis imperfecta
types. In cases of dermatofibrosarcoma protuberans the gene is involved in a translocation
t(17;22)(q22;q13) with the PDGF gene.;
