Abstract: | A patient with the phenotype of trisomy 21 and increased activity of superoxide dismutase A is reported with partial trisomy for the distal portion of 21q. The exceptional feature in this case is a 45-chromosome karyotype due to the translocation of two chromosomes 21 onto the distal end of 14q. |
