摘要
目的分析Turner综合征不同核型的遗传学特征、临床表现及其关系。方法外周血淋巴细胞G带分析。结果 16例Turner综合征患者中单体45,X0 6例(37.50%),46,X0/46,XX嵌合体1例(6.25%),46,Xi(Xq)1例(6.25%),47,XXX 4例(25.00%),46,XY/45,X0 3例(18.75%),46,XX,del(Xq24)1例(6.25%)。结论 X染色体数目异常及结构畸变是导致Turner综合征的主要原因,多种异常核型均不同程度导致女性生长缓慢、性腺发育不良、闭经及智力低下等其他器官功能异常。
Objective : To analyze the association between various chromosome karyotypes of Turner Syndrome and their clinic man- ifestation. Methods : G banding of peripheral blood lymphocytes were used to analyze chromosomes in the patients. Results : Among 16 Turner syndrome patients there were 6 case of mosaic 45, XO (37.50%) ; 1 case of mosaic 46, X0/46, XX (6. 25% ) ; 1 case of 46, Xi (Xq) (6.25%); 4 case of 47, XXX (25.00%); 3 case of 46, XY/45, X0 (18.75%); 1 case of 46, XX, del (Xq24) (6. 25% ). Conclusion: The primary reason of turner syndrome is the numerical anomalies and structural aberrations aberra- tions of X chromosome. Many kinds of organ dysfunctions, such as slow growth, gonadal dysgenesis, amenorrhea and mental retardation are caused by abnormal karyotype.
