This paper describes a retarded girl who had a severe seizure disorder and a few minor anomalies, and who was found to have a “G‐sized” supernumerary chromosome in all her cells which were examined. Studies of the patient's and her parents' chromosomes by a variety of techniques suggest that the supernumerary chromosome arose following a prezygotic maternal 13;15 translocation.
