There are two errors in Table 5 on page 546 of this article. The reported clinical effects of variant −308 G>A from Seitz et al. (2007) and Cuchacovich et al. (2006) should both read 'Associated with decreased efficacy' not 'Associated with increased efficacy' as originally printed. The error has been corrected for the HTML and PDF versions of the article.
