KERA

The protein encoded by this gene is a keratan sulfate proteoglycan that is involved in corneal transparency. Defects in this gene are a cause of autosomal recessive cornea plana 2 (CNA2).[provided by RefSeq, May 2010]

Keratocan

May be important in developing and maintaining corneal transparency and for the structure of the stromal matrix.

Cornea plana 2, autosomal recessive (CNA2):
A severe form of cornea plana, a rare ocular disorder characterized by flattened corneal curvature leading to a decrease in refraction, reduced visual activity, hyperopia, hazy corneal limbus, opacities in the corneal parenchyma, and marked arcus senilis often detected at an early age. CNA2 patients manifest extreme hyperopia and additional ocular anomalies such as malformations of the iris, a slit-like pupil, and adhesions between iris and cornea.
