For example, genes contributing to the GO term “collagen binding” such as collagens Col6a1 and Col6a2 [52] and procollagen C-endopeptidase enhancer Pcolce (its paralog Pcolce2 also figuring on the list) [53], have been linked to myopathies, while Tgfbi (transforming growth factor beta induced) has been linked to corneal dystrophies [54]. This evidence concerns the gene COL6A2 and corneal dystrophy.
