<unk>  is inherited in autosomal recessive fashion and is thought to be caused by the lack or abnormal configuration of keratan sulfate. Most cases of<unk>  are caused by mutations in CHST6 gene. The gene CHST6 is a carbohydrate sulfotransferase encoding an enzyme designated corneal N-acetylglucosamine-6-sulfotransferase. In<unk>  type I, various mutations lead to inactivation of the enzyme, in<unk>  type II, inactivation is caused by large deletions and/or replacements in the gene.
