Abstract excerpt
We have investigated a family with an autosomal dominantly inherited connective-tissue defect causing extreme joint hypermobility, premature osteoporosis and late-onset fractures. Analysis of collagenous proteins from affected individuals showed a deletion in some alpha 2(I) chains. Peptide mapping localized this to the CB peptide alpha 2CB4, which covers the N-terminal one-third of the protein chain. Polymerase...
