Abstract

Purpose: Evaluation of recurrent spontaneous abortions (RSA) can be challenging for a Obstetrician. In case of early first trimester abortions, chromosomal abnormalities can be identified as an important cause. We analysed the RSA cases followed up and diagnosed in the Genetic Clinic or Genetic Lab of 2 hospitals in the region. Methods: Those couples with 3 or more spontaneous abortions were included in the analysis. Karyotyping was one using standard protocol with G-banding and reporting as per ISCN guidelines. Results: Of 97 RSA couples, 20 showed chromosomal abnormalities, and 15 of these had balanced chromosomal rearrangements. The age ranged from 22 years to 37 years, and the median number of abortions was 4. Complex chromosomal rearrangement was seen in 2 couples, in one partner. The spectrum of chromosomal anomalies in couples with RSA is discussed here. Conclusions: Frequency of chromosomal abnormalities in RSA was higher in present study compared to previous studies. Reciprocal translocations were commonest abnormality.
