Mutations of Nr2e3 are correlated with several hereditary retinopathies, such as enhanced short‐wavelength sensitive cone syndrome,[27] retinal pigments,[28] Goldmann–Favre syndrome.[29] Except for the retina, Nr2e3 is also expressed in other tissues, including the breast and liver, and is related to breast and liver cancer. The gene discussed is NR2E3; the disease is liver cancer.
