Expression of Concern (EOC) is a correction or erratum published by the editors' preference to inform readers about serious concerns or potentially misleading information on a published article. We will mostly finalize our investigations about a suspicious case before issuing a notice; nevertheless, we may publish an EOC as a provisional notice in some rare cases. On infrequent occasions, an EOC may be issued while an investigation is underway but a judgment will not be available for a considerable time.
An EOC is written by the journal's Editor(s)-in-Chief. When published, an EOC is posted at the top of the article's webpage and linked to the article's publication record, similar to a correction.
Publishing an EOC does not change the status of the linked published article. After an EOC is published, the same article may be corrected or retracted, or the EOC itself may be corrected or retracted, depending on the editors' assessment of information, data, and/or materials received in subsequent discussions.
We also attempt to inform the authors of the affected article before publishing an EOC, but we do not require the authors' approval or agreement. We commit ourselves to publish data or other materials received from the authors as supporting files with an EOC; in such cases, authors are consulted and can elect not to have their files/materials published, though this may affect the editorial decision to resolve the issue with an EOC.
Human Genetics and Genomics publishes an EOC as a new article with the type of correction letter and makes a link to the preliminary article.
