UniProt Annotation
Function May be important in developing and maintaining corneal transparency and for the structure of the stromal matrix.
Subcellular Localization Secreted, extracellular space, extracellular matrix {ECO:0000250}.
Disease Associations The autosomal recessive cornea plana 2 (CNA2) [MIM:217300]: In CNA2, the forward convex curvature is flattened, leading to a decrease in refraction, reduced visual activity, extreme hyperopia (usually plus 10 d or more), hazy corneal limbus, opacities in the corneal parenchyma, and marked arcus senilis (often detected at an early age). CNA2 is a rare disorder with a worldwide distribution, but a high prevalence in the Finnish population. {ECO:0000269PubMed:10802664, ECO:0000269PubMed:11726611}. Note=The disease is caused by mutations affecting the gene represented in this entry.
Tissue Specificity Cornea. Increased expression in the stroma of keratoconus corneas. Also detected in trachea, and in low levels, in intestine, skeletal muscle, ovary, lung and putamen. {ECO:0000269PubMed:11683372}.
