In the article by Mu et al, “The Cypher and Enigma Homolog Protein Are Essential for Cardiac Development and Embryonic Survival,” which published online May 5, 2015, and appeared in the May 2015 issue of the journal (J Am Heart Assoc. 2015;4:e001950 doi: 10.1161/JAHA.115.001950), the Sources of Funding section contained an error. The first sentence read “Chen is funded by grants from the National Institute of Arthritis and Musculoskeletal and Skin (R01AR059334) and the National Heart, Lung, and Blood Institute.” It should read “Chen is funded by grants from the National Heart, Lung, and Blood Institute, and is an American Heart Association Endowed Chair.”
The authors regret this error.
