Identification and characterization of the human type II collagen gene (COL2A1).


The gene contained in the human cosmid clone CosHcol1, previously designated an alpha 1(I) collagen-like gene, has now been identified. CosHcol1 hybridizes strongly to a single 5.9-kilobase mRNA species present only in tissue in which type II collagen is expressed. DNA sequence analysis shows that this clone is highly homologous to the chicken alpha 1(II) collagen gene. These data together suggest that CosHcol1 contains the human alpha 1(II) collagen gene COL2A1. The clone appears to contain the whole gene (30 kilobases in length) and will be extremely useful in the study of cartilage development and for identifying those inherited chondrodystrophies in which defects occur in this gene.
