Fourteen families with genetically determined posterior retinaldystrophies were studied by fluorescein angiography.
2
Single gene defects cause the majority of these retinaldystrophies.
3
Initially, the identification of a mutation in the rds mouse model defined the role of this gene in hereditary retinaldystrophies.
4
Mouse mutants with retinaldystrophies have provided a valuable resource to discover human disease genes and helped uncover pathways critical for photoreceptor function.
5
Inherited retinaldystrophies represent the most important cause of vision impairment in adolescence, affecting approximately 1 out of 3000 individuals.
6
The molecular data for CRB1 and RPE65 support previous hypotheses that LCA can represent the severe end of a spectrum of retinaldystrophies.
