Researchers identify a genetic mutation associated with high risk of age-related macular degeneration

Age-related macular degeneration (AMD) is the leading cause of severe visual loss among the elderly. Researchers had previously identified several relatively common genetic variants which together predict a person's increased risk for AMD, but a significant number of persons without the disease also have these variants. Now, for the first time, investigators have been able to clearly show a specific rare mutation called CFH R1210C that predicts a very high risk of disease and is extremely uncommon among individuals who do not have the disease.
