MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] 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]
PHENOTYPE: Mice homozygous for disruptions in this gene have a thinner than normal corneal stroma with thicker collagen fibers which were less regularly packed. [provided by MGI curators]
