Brachmann-de Lange syndrome with normal IQ
Abstract
The Brachmann-de Lange syndrome is a disorder with a high degree of clinical variability, generally associated with moderate to severe mental retardation. To date, 7 previous cases of Brachmann-de Lange syndrome with normal intelligence (IQ > 70) have been described. We report the eighth case of Brachmann-de Lange syndrome with normal intelligence. In reviewing thr literature, consistent clinical menifestations seen in these 8 patients that are of prognostic value are the absence of significant limb anomalies and birth weight > 2,500 g. © 1993 Wiley-Liss, Inc.
