title: De novo distal trisomy 17q.
abstract: A boy is described, who shares many of the clinical features found in the few patients with a partial 17q trisomy known at present. Karyotyping revealed a de novo 17q+ chromosome, interpretable as a tandem duplication of the distal long arm region 17q25.
