In the version of this article initially published, in Table 2, first column, “m.13095T > C” should have been “m.130bT > C,” where “b” refers to the footnote “Characters hidden to respect confidentiality,” as with the other three from the Newcastle Group. In addition, the footnote “a” for Table 2 should have read “http://hfeaarchive.uksouth.cloudapp.azure.com/www.hfea.gov.uk/docs/Fourth_scientific_review_mitochondria_2016.pdf” rather than “Personal communication.” The following acknowledgment was omitted: “The authors thank Rob Taylor, Charlotte Alston, Emma Watson, Sam Byerley, Jane Stewart and Robert McFarland (Wellcome Centre for Mitochondrial Research Newcastle University and Newcastle upon Tyne Hospitals NHS Foundation Trust) for unpublished data included in Table 2.” The errors have been corrected in the HTML and PDF versions of the article.
