Summary
Recurrent spontaneous miscarriages in couples can be linked to chromosome aberrations. Cytogenetic studies found these abnormalities in 6.2% of cases, with reciprocal translocations being most common.
Area of Science:
- Human Genetics
- Reproductive Medicine
- Clinical Cytogenetics
Background:
- Recurrent spontaneous miscarriage (RSM) affects a significant number of couples.
- Identifying the underlying causes of RSM is crucial for reproductive counseling and management.
- Chromosomal abnormalities are a known, though not fully elucidated, factor in RSM.
Purpose of the Study:
- To investigate the prevalence of chromosomal aberrations in couples experiencing recurrent spontaneous miscarriages.
- To identify specific types of chromosome abnormalities associated with RSM.
- To provide cytogenetic data for couples seeking diagnosis for RSM.
Main Methods:
- Cytogenetic analysis was performed on 129 couples with a history of recurrent spontaneous miscarriages.
- Karyotyping was utilized to detect structural and numerical chromosome abnormalities.
- Statistical analysis was applied to determine the frequency of observed aberrations.
Main Results:
- Chromosome aberrations were identified in 8 out of 129 couples (6.2%).
- Reciprocal translocations were the most frequent aberration, found in 6 couples.
- Pericentric inversion of chromosome 9 was detected in 3 couples (2.3%), and chromosome polymorphism was observed in 20% of cases.
Conclusions:
- Cytogenetic evaluation is valuable for couples with recurrent spontaneous miscarriages.
- Specific chromosomal aberrations, such as reciprocal translocations, are significant factors in RSM.
- Further research into the genetic contributions to RSM is warranted.
