In the version of this article initially published, the immunofluorescence staining images for TGFBI in Fig. 7 and Supplementary Fig. 7 inadvertently displayed the same image. This error does not affect the conclusions for either figure (the staining pattern is identical). Fig. 7 has been replaced with the correct image in the HTML and PDF versions of the article.
