, the eye, and in the ear. Type XXVII collagen is related to the "fibrillar" class of collagens and may play a role in development of the skeleton. Fibrillar collagens, such as COL27A1, compose one of the most ancient families of extracellular matrix molecules. They form major structural elements in extracellular matrices of cartilage, skin, and tendon.
