To the Editor We are writing to correct errors in our previously published report, titled “Symptomatic Congenital Hemangioma and Congenital Hemangiomatosis Associated With a Somatic Activating Mutation in GNA11.”1 In Figure 3B, which depicts the region of the p.Q209P somatic mutation in our tumor sample viewed using the Integrated Genome Viewer software, the horizontal gray bars representing individual exome reads were off center. This was the result of our graphics software misaligning the reads with the histogram above it, causing a strange step-off to be seen. Herein, we provide a correctly aligned Figure.
