To the Editor:

The review of the text Genetic Testing: Care, Consent and Liability by Kathy Hudson (Nat. Genet. 38, 603; 2006) referred to an apparent error concerning the case of Breyne V. Hudson on page 116. The publishers of the text, John Wiley & Sons, Inc., have now acknowledged that this was the result of a “significant printing error” and have issued an Erratum.

The sentences in question read, as finally printed in the book, “The woman proceeded to have an abortion. The following day, the physician telephoned the woman, admitted that he had been mistaken and said that the baby actually had Trisomy 21 (Downs Syndrome), a condition that could not cause retardation but could result in developmental delays in learning, speech, and motor skills.” The Erratum states, “Somehow, during the final stages of the production process at John Wiley & Sons, Inc., the reference to '47,XXX' was replaced with the phrases 'Trisomy 21 (Downs Syndrome)'. The Publisher regrets this error and wishes to take full responsibility for it, as it was clear that the Editors had indeed approved the correct reference to 47,XXX.”
