Abstract:
Objective: To investigate 2 450 patients' chromosomes with a history of abnormal pregnancy such as spontaneous abortion, fetal death, teratism, and oligospermia and to explore the relationship between balanced chromosomal translocation and abnormal pregnancy. Methods: Chromosomal analysis was made by peripheral lymphocytes culture and G-banding. Results: 22 cases of balanced translocation were discovered(3 cases of robertsonian translocation)accounting for 0.90%. Spontaneous abortion, fetal death, teratism, and oligospermia were main manifestations of abnormal pregnancy. Conclusion: Balanced chromosomal translocation was a major reason for abnormal pregnancy. Examination of heredity and prepotency, prenatal diagnosis, guidance on assisted production were necessary for balanced chromosomal translocation carriers.
Key words: abnormal pregnancy, genetic counseling, chromosome, balanced translocation
