Cytogenetic studies in couples with multiple spontaneous abortions
Acta Anthropogenetica
|January 1, 1983
Summary
Chromosome abnormalities were identified in 5 of 222 individuals from couples experiencing recurrent pregnancy loss. These included balanced translocations and a rare mosaic condition, highlighting the importance of genetic screening in reproductive health.
Area of Science:
- Human Genetics
- Reproductive Biology
- Cytogenetics
Background:
- Recurrent spontaneous abortion (RSA) affects a significant number of couples.
- Identifying underlying genetic causes is crucial for reproductive counseling.
- Chromosomal abnormalities are a known risk factor for RSA.
Purpose of the Study:
- To investigate the prevalence of chromosomal aberrations in couples with a history of two or more spontaneous abortions.
- To identify specific types of chromosomal abnormalities contributing to recurrent pregnancy loss.
Main Methods:
- Karyotyping was performed on 222 individuals from 117 couples.
- Standard cytogenetic techniques were utilized for chromosome analysis.
Main Results:
- Chromosomal aberrations were detected in 5 out of 222 individuals (2.25%).
- Four individuals had balanced translocations.
- One individual presented with a 46,XX/45,X mosaic karyotype.
Conclusions:
- A notable proportion of couples with recurrent pregnancy loss harbor chromosomal abnormalities.
- Balanced translocations and mosaicism are significant findings in this population.
- Karyotyping is an essential diagnostic tool for couples undergoing genetic counseling for recurrent spontaneous abortions.
