Predictive Test for Age-Related Macular Degeneration in Asymptomatic Individuals
Description of Invention:
Age-related macular degeneration (ARMD) is the leading cause of severe, irreversible vision loss for those over the age of fifty in the United States and in other developed countries. Thirteen million Americans over the age of forty have ARMD. ARMD is caused by the deterioration of the central area of the retina, or macula, resulting in a loss of central vision. This disease is believed to be a multigenic disorder, and is triggered by environmental factors such as smoking, age or diet in genetically susceptible individuals.
The present invention describes a highly predictive genetic test for universal practical clinical use to identify individuals at increased risk for ARMD. It comprises a rapid, accurate and affordable genetic screen, utilizing DNA microarray technology on a single chip. Sixteen genes are screened for 90 mutations/polymorphisms associated with ARMD, with a high predictive power (up to 92.7%) to identify asymptomatic carriers at risk. Accurate prediction of genetic susceptibility to this disorder will allow interventions to protect at-risk individuals.
Applications:
Method to diagnose ARMD
Diagnostic kit to identify asymptomatic individuals at risk for ARMD
Method to identify genetic factors in an affected individual, aiding in the development of a tailored therapeutic plan
Provide genetic epidemiologic data to elucidate the role of genetic factors in the progression of the disease
Advantage:
Easy, rapid high-throughput method to diagnose ARMD
Development Status:
This technology requires analytic validation before commercialization.
Market:
There are an estimated 15 million cases of age-related macular degeneration in the United States, and 50 million cases worldwide.
