本文用聚合酶链反应 (PCR)检测 7例Turner综合征患者是否具有Y染色体特异性基因 SRY基因 (sex deter mineregionY) ,以检查出含有Y染色体或其片断的隐匿型嵌合体。结果 :7例患者SRY基因均阴性。结论 :含有Y染色体或其片段的隐匿型嵌合体患者在Turner综合征患者中所占的比例可能较小。
In this paper, polymerase chain reaction (PCR) was used to detect whether 7 patients with Turner syndrome have sex deter mineregionY to detect the occult chimera containing Y chromosome or its fragment. Results: All 7 patients had negative SRY gene. CONCLUSIONS: Patients with occult chimeras containing Y chromosomes or fragments thereof may account for a relatively small proportion of patients with Turner’s syndrome.
