[Molecular-genetic basis of tapetoretinal degeneration].

The review on problem tapetoretinal degeneration (TD) which represents serious enough and incurable disease revealed with frequency 1 : 3500-5000 in general population is presented. The most often reason of occurrence TD are mutations in RHO, RDS and RPE65 genes. The precise interrelation of pigmentary degenerations of a retina and mutations in genes RHO, RDS and RPE65 will allow to develop approaches of DNA--diagnostics of hereditary dystrophies of a retina so frequently meeting in clinical practice of the ordinary ophthalmologist, and also to pass at medical genetics consultation from probability estimations of risk of disease to unequivocal.
