N normal phenotype
homeostasis/metabolism
• retinyl ester levels are reduced in the liver, lungs, eye, and brain and are higher in adipose tissue than in wild-type on a normal vitamin A-sufficient diet and are reduced on a vitamin A-deficient diet
• retinol levels are reduced in the liver, lungs, and eyes and are increased in the kidney, adipose tissue, muscle, brain, and tongues compared to wild-type on a normal vitamin A-sufficient diet, however no differences in serum retinol levels
• almost complete absence of retinol in tissues after 6 weeks on a vitamin A-deficient diet, indicating that homozygotes become vitamin A-deficient more rapidly
• serum retinol levels are significantly lower compared to wild-type on a vitamin A-deficient diet, indicating increased susceptibility to vitamin A-deficiency
