Molecular genetics of inherited eye disorders.
In the past 10 y, there have been considerable advances in the mapping, isolation, and characterization of many genes for important ocular conditions: retinitis pigmentosa, Norrie disease, Waardenburg syndrome, choroideremia, aniridia, retinoblastoma, and others. The candidate gene approach has now supplemented classical linkage studies and positional cloning in the investigation of ocular disorders. Developmentally expressed genes and animal models have provided insights as to the etiology of other disorders. With this knowledge at hand, genetic counselling for heritable eye diseases has been greatly improved.
