title: Translocation/duplication of 9p onto a duplicated 4q.
abstract: A 5-month-old girl with the classical dysmorphism of the 9p trisomy syndrome and a severe heart defect was found to have an unbalanced translocation of 9pter-->p22 onto q35 of a chromosome 4 with an inverted duplication of q32-->q35. This concurrence of two de novo rearrangements suggests that the breakpoint at 4q35 not only participated in the translocation but also predisposed to the segmental duplication of 4q.
