In our article in the March 1987 issue of the Archives,1 a confusing statement appears on pages 242 and 245. It equates Klinefelter's syndrome with XYY chromosome abnormality. The correct statement on both pages should read XYY chromosome abnormality, and Klinefelter's syndrome should be omitted.
We apologize for this error that occurred during the editing process and that we did not catch while proofreading the manuscript.
