Retinitis Pigmentosa Fact #8
I've already said that RP is caused by a mutated gene, well, there are many types of genes that can be mutated to cause RP. In 1989, a mutation for the gene rhodopsin was discovered. Rhodopsin is essential in visual transduction cascade which enables vision in low light situations. Since 1989, over 100 other mutations for this gene have been identified and make up about 15% of all types of Retinal Degeneration.
