Description : Oguchi disease is a rare autosomal recessive form of congenital stationary night blindness
in which all other visual functions, including visual acuity, visual field, and color
vision, are usually normal. A typical feature of the disease is a golden or gray-white
discoloration of the fundus that disappears in the dark-adapted state and reappears
shortly after the onset of light (Mizuo phenomenon, or Mizuo-Nakamura phenomenon).
The course of dark adaptation of rod photoreceptors is extremely retarded, whereas
that of cones appears to proceed normally (summary by Fuchs et al., 1995). - Genetic
Heterogeneity of Oguchi Disease Oguchi disease-2 (CSNBO2) is caused by mutation in
the rhodopsin kinase gene (GRK1; 180381) on chromosome 13q34.;
Inheritance : Autosomal recessive;
Molecular basis : Caused by mutation in the S-antigen gene (SAG, 181031.0001);
Prefixed ID : #258100;
