A University of Rochester Medical Center cardiology research team has won a $4 million National Institutes of Health grant to study a genetic disorder that causes heart arrhythmias and can lead to sudden death, URMC officials said Tuesday.
Led by Arthur Moss M.D., the cardiology team plans a five-year study of Long QT Syndrome, type 3. Researchers at Columbia University New York Presbyterian Hospital are also involved.
The project is to analyze cellular mechanisms involved in the Long QT 3 disorder, look at ways in which the syndrome overlaps other heart rhythm disorders and investigate treatments for the condition.
With the establishment in 1979 of a registry of Long QT families, Moss created one of the first international genetic-disease data bases. Tracking families in the registry has helped scientists identify 10 genes and 500 genetic mutations figuring in variations of the syndrome.
Moss recently was named to the Bradford C. Berk M.D., Ph.D. Distinguished Professor of Medicine endowed chair.
