Several author names—Susanne Wendt, MD, Ana Cristina Puga, MD, PhD, and Anne Marie Conway, MHA, RN—were misspelled or incorrect in the above article that ran in the August issue.

The author lines should read as follows: Joseph Muenzer, James E. Wraith, MD, Michael Beck, MD, Roberto Giugliani, MD, PhD, Paul Harmatz, MD, Christine M. Eng, MD, Ashok Vellodi, MD, Rick Martin, MD, Uma Ramaswami, MD, Muge Gucsavas-Calikoglu, MD, MPH, Suresh Vijayaraghavan, MD, Susanne Wendt, MD, Ana Cristina Puga, MD, PhD, Brian Ulbrich, MD, Marwan Shinawi, MD, Maureen Cleary, MD, Diane Piper, MSc, CStat, Anne Marie Conway, MHA, RN, and Alan Kimura, MD, PhD.

Also, the Acknowledgement that ran on page 472 was incomplete. The following sentence should be added:

“This work was supported in part by NIH GCRC grant # M01-RR00188 to Texas Children's Hospital granted to Dr. Christine Eng, by NIH GCRC grant # M01-RR01272 to the PCRC and CHCR at Oakland Children's Hospital granted to Dr. Paul Harmatz, and by NIH GCRC grant # M01-RR00036 to Washington University granted to Dr. Rick Martin.”

We regret the errors.
