摘要 目的 研究先天性心脏缺陷患者中染色体 2 2 q11缺失发生率和表型效应。方法 应用生物素标记染色体2 2 q11内DNA探针进行荧光原位杂交 (FISH)技术 ,对 36例先天性心脏病患者进行检测分析。结果 在 36例先天性心脏病患者中 ,发现 4例患者有染色体 2 2q11缺失 ,缺失率为 11.1%。结论 染色体 2 2 q11缺失是导致先天性心脏缺陷的重要因素 ,荧光原位杂交法是诊断 2 2 q11缺失准确。 Objective: To study the incidence and the phenotype effects of chromosome 22q11 deletion in patients with congenital heart defect. Methods: 36 patients with congenital heart disease was detected with fluorescence in situ hybridization using chromosome 22q11 DNA probe labeled avidin. Results: 4 chromosome 22q11 deletion were found in 36 patients with congenital heart disease,. The deletion rate was 11.1%. Conclusion: The chromosome 22q11 deletion are an important cause of congenital heart disease. The fluorescence in situ hybridization is an accueate and specific method for diagnosis of the chromosome 22q11 deletion.
