Molecular assay reagents intended to identify mutations in the collagen, type I, alpha 1 (COL1A1) gene, located at chromosome 17q21.3-q22.1, which provides instructions to make type I collagen, pro-alpha 1 (I) chain. Mutations at this locus have been identified in patients with diseases that include osteogenesis imperfecta (types I to IV) and Ehlers-Danos syndrome.
