UBIAD1 is the gene responsible for Schnyder corneal dystrophy (SCD), a rare autosomal dominant disorder that manifests as a progressive bilateral corneal opacification due to the widespread deposition of intercellular and extracellular cholesterol and phospholipids in the epithelium, Bowman’s layer, and stroma of the cornea [146,147,148]. Here, UBIAD1 is linked to Schnyder corneal dystrophy.
