To the Editor: Van Woert, Yip and Balis1 report an alteration in the isoelectric focusing of the enzyme hypoxanthine-guanine phosphoribosyltransferase, E.C. (HGPRT), in red-cell lysates of patients affected with the Gilles de la Tourette syndrome. Because of similarities to the X-chromosome-linked HGPRT deficiency syndrome (Lesch-Nyhan), males being more frequently affected than females and some patients having a clinical history of self-mutilation,2 the authors interpret their results as providing evidence that purine metabolism is abnormal in these cases. We have examined the isoelectric focusing properties of HGPRT in red-cell lysates of six unrelated male patients with the Gilles de la Tourette.
