title: Complex chromosomal rearrangement involving chromosomes 11, 13, 14 and 18 resulting in monosomy for 13q32----qter.
abstract: A five-year-old boy with speech delay, minor facial abnormalities and borderline psychomotor retardation was found to have a complex de novo double translocation involving four chromosomes resulting in monosomy for the segment 13q32----qter. Chromosomes involved were 11, 13, 14, and 18. The translocation between chromosome 11 and 13 was unbalanced with the loss of the segment 13q32----qter. The second translocation between 14 and 18 was apparently balanced.
