A genetic variation believed to increase risk for heart failure in people of African or Latino ancestry has been identified in a new study by researchers from the Icahn School of Medicine at Mount Sinai and Perelman School of Medicine at the University of Pennsylvania.

The study found that the transthyretin or TTR V122I genetic variant was significantly associated with heart failure and that heredity transthyretin amyloid cardiomyopathy (hATTR-CM) caused by this variant was confirmed at appreciable frequency in individuals of African or Latino ancestry. The results suggest a significant under-recognition and under-diagnosis of this potentially fatal disease.

The results of the study were published in JAMA.
