目的:探讨人染色体罗伯逊易位(Rob)的临床效应。方法:分析遗传咨询门诊不育、不孕、反复流产患者共302例,应用常规细胞遗传学GTG和FISH方法分析患者核型组成。结果:检测出Rob核型6例。结论:结合资料分析认为Rob携带者会产生遗传物质部分重复或缺失的配子,导致不育或孕早期自发流产。
Objective: To investigate the clinical effect of human chromosome Robertson’s translocation (Rob). Methods: A total of 302 cases of infertility, infertility and recurrent spontaneous abortion were analyzed. The karyotypes of patients were analyzed by conventional cytogenetics GTG and FISH. Results: Rob karyotype was detected in 6 cases. Conclusion: According to the data analysis, Rob carriers will produce gametes with partially duplicated or missing genetic material, resulting in infertility or spontaneous abortion in early pregnancy.
