A mentally retarded boy with multiple malformations was found to have trisomy for the distal two-thirds of the short arm of chromosome 20 (trisomy 20p), resulting from a paternal translocation (5;20)(p15;p11). The patient had a cleft palate, a feature not present in other trisomy 20p patients. A review of the reported trisomy 20p patients indicates that their varied features do no constitute a readily recognizable clinical syndrome.
