Abstract
- The aim of this study was to investigate the contribution of chromosomal anomalies and the frequency of particular types of aberrations in general couples preparing for pregnancy and make recommendations for pregnancy on the basis of the medical literature. Atotal of 6,198 general couples were included in the present study. The karyotypes were generated from the peripheral blood lymphocyte cultures and the cytogenetic analysis was performed using G-banding. In 12,396 cases, chromosomal anomalies were detected in 59 cases (0.48%, 59/12,396). Among of them, the frequency of translocation was 0.35% (n 5 43). Sex chromosomal anomalies accounted for 0.07% (n59), including Klinefelter syndrome (KS) (n54), Turner syndrome (TS) (n 5 4), and XYY syndrome (n 5 1). The others, including inversions (n 5 6) and deletion (n 5 1), accounted for 0.06%. Our study indicates that clinically important chromosomal defects are present at a remarkable frequency in the general couples in eastern China, suggesting pre-pregnancy cytogenetic analysis should be routinely performed among general couples in this area so that informed decision can be made, which will help to improve the quality of the pregnancy.
