Enhanced S-cone syndrome
Definition:
Enhanced S-cone syndrome (ESCS) is a rare autosomal recessive retinal dystrophy that results in an increased function of the short wavelength-sensitive (S) cones. It is characterized by night blindness, cystoid maculopathy and degenerative changes of the vascular arcades. Mutations in the NR2E3 gene, which encodes a photoreceptor cell-specific nuclear receptor, cause this disease.
