Missing Units of Measure.—In the article entitled "Nonphenylketonuric Hyperphenylalaninemia" published in the December 1989 issue of AJDC (1989;143:1464-1466), information was incomplete in one of the tables. In the second column of Table 1, "Pheny" indicates phenylalanine and the values, given in milligrams per deciliter, are of levels taken at the time of the examination. The brace indicating Wechsler Scales should have been over IQ scales only and should not have included readings of phenylalanine levels.
