abstract：BACKGROUND:Balanced complex translocations (BCTs) are rare events, they may result in reproductive failures: spontaneous abortions, missed abortions, stillbirths, congenital malformations in children, and male infertility. BCTs belong to the group of complex chromosome rearrangements (CCRs) - up to date about 260 cases...
