Four amino acid changes are associated with the Aldh3a1 locus polymorphism in mice which may be responsible for corneal sensitivity to ultraviolet light.

Abstract excerpt

We studied the phenotype and the nucleotide sequence for the cDNAs of the Aldh3a1a and Aldh3a1c allelic forms of the dioxin-inducible cytosolic aldehyde dehydrogenase (ALDH3A1) present in inbred mouse strains. This gene is constitutively expressed in cornea, stomach, skin, urinary bladder and lungs. The Aldh3a1a allele is found in most inbred mouse strains and codes for a 'high-activity' corneal enzyme compared...
