Chromosomal rearrangement involving chromosomes 4, 6, 11 and 11.

The case of a healthy 29-year-old woman is reported who had a history of three early spontaneous abortions. Chromosomal analysis of the mother of the patient showed a balanced karyotype of 46,XX,t(6;11) (q24; q21), whereas the chromosomes of her father were normal. The karyotype of this patient is thus a combination of a familial translocation 6;11 and a de novo translocation 4;11, which is very rare.
