NCIt definition : Human COL18A1 wild-type allele is located in the vicinity of 21q22.3 and is approximately
109 kb in length. This allele, which encodes collagen alpha-1 (XVIII) chain protein,
plays a role in the development of both the neural tube and the retina. Mutations
in the gene are associated with Knobloch syndrome.;
NCIt note : The COL18A1 gene product can be cleaved by various proteases to release the antiangiogenic
peptide endostatin.;
