Mutations in the gene encoding UbiA prenyltransferase domain-containing protein-1 (UBIAD1) cause Schnyder corneal dystrophy (SCD), a rare autosomal dominant eye disease characterized by opacification of the cornea (Klintworth, 2009; Weiss, 2009; Orr et al., 2007; Weiss et al., 2007). This evidence concerns the gene UBIAD1 and Schnyder corneal dystrophy.
