PURPOSE: Chromosomal alterations are a major cause of clinically recognized abortions. So cryptic chromosomal rearrangements could be responsible for recurrent miscarriages. METHODS: The study was performed on 18 clinically normal couples who had four or more spontaneous abortions and whose karyotypes were found to be normal. Fluorescence in situ hybridization with specific probes of subtelomeric regions was used after optimizing the amount of probe. RESULTS: Only one subtelomeric translocation was detected between 2p and 3p chromosomes, in a female with seven miscarriages. CONCLUSION: Subtelomeric rearrangements are infrequently related to multiple miscarriages. This kind of studies can be considered specially worthy when a couple have had not only abortions but also offspring with mental and physical anomalies. Thus, possible initial studies should focus on affected children or fetus.
