Reciprocal translocations in couples with spontaneous abortions
Acta Europaea Fertilitatis
|June 1, 1982
Summary
Cytogenetic analysis is recommended for couples experiencing recurrent spontaneous abortions. This investigation can identify reciprocal translocations, even without stillbirths or birth defects, aiding reproductive health.
Area of Science:
- Human Genetics
- Reproductive Medicine
- Cytogenetics
Background:
- Recurrent spontaneous abortion (RSA) affects a significant number of couples.
- The underlying causes of RSA are diverse, including chromosomal abnormalities.
- Cytogenetic analysis is a key diagnostic tool in evaluating couples with pregnancy loss.
Purpose of the Study:
- To investigate the frequency of reciprocal translocations in couples with a history of spontaneous abortions.
- To determine the clinical utility of cytogenetic analysis in RSA cases, irrespective of stillbirths or malformations.
Main Methods:
- Studied a cohort of 87 couples with one or more spontaneous abortions.
- Performed cytogenetic analysis to detect chromosomal abnormalities, specifically reciprocal translocations.
- Conducted a literature review and re-analysis of existing data to estimate translocation frequencies in homogeneous samples.
Main Results:
- Reciprocal translocations were identified in 3 out of the 87 studied couples.
- Literature re-analysis provided estimates for translocation frequency in specific patient subgroups.
- The findings suggest a non-negligible prevalence of translocations in couples with RSA.
Conclusions:
- Cytogenetic investigation is advisable for couples with a history of frequent spontaneous abortions.
- This recommendation holds true even in the absence of stillborn infants or diagnosed congenital malformations.
- Identifying chromosomal translocations can inform genetic counseling and reproductive planning for affected couples.
