Ethics approval and consent to participate
: This study was approved by the institutional review boards at the Mayo Clinic (14–009934) and Olmsted Medical Center (008-OMC-15). General authorization to review medical records for research in accordance with Minnesota Statute was checked, and no medical records were reviewed of any child for whom the general research authorization has been refused. As some of the subjects have left the community, it is practically impossible to locate all subjects who are eligible to the study and obtain consent for this proposed study. Therefore, the need for consent was waived by the institutional review boards at two institutions mentioned above.
