In the article by Lehnart et al, “Inherited Arrhythmias: A National Heart, Lung, and Blood Institute and Office of Rare Diseases Workshop Consensus Report About the Diagnosis, Phenotyping, Molecular Mechanisms, and Therapeutic Approaches for Primary Cardiomyopathies of Gene Mutations Affecting Ion Channel Function,” which appeared in the November 13, 2007, issue of the journal (Circulation. 2007;116:2325–2345), a number of errors occurred. These erros have been corrected in the current online version of the article.
In Tables 1 through 5, numerous errors occurred in shadings (added to enable gene cross referencing), formatting, use of special symbols, and footnotes. Additionally, references have been added to the body of Table 3. In Table 5, middle panel, second-to-last row, the up arrow should be replaced by a down arrow, and in the bottom row, a reference should be added.
The publisher regrets these errors.
Throughout the article, the A-kinase–anchoring protein gene AKAP9gene was mistakenly omitted from discussions of long-QT Syndrome–susceptibility genes. The gene has been added to the text where relevant and Tables 2 and 3 have been updated to include the gene. Also, an article presenting important findings about the gene (Chen L, Marquardt ML, Tester DJ, Sampson KJ, Ackerman MJ, Kass RS. Mutation of an A-kinase–anchoring protein causes long-QT syndrome. Proc Natl Acad Sci U S A. 2007;104:20990–20995) should have been cited as “in press.” It has been added to the article with complete publication information as reference 159a.
The authors regret these omissions.
On page 2326, under Novel Clinical and Genetic Aspects of SCN5A Phenotypes, line 16, the citation to reference 27 should be changed to 29. The authors regret this error.
On page 2336, in the paragraph that begins, “Identification of mutations…” the designations “LQT1” through “LQT6” should be “LQTS1” through LQTS6.”
The authors regret the error.
