Fluorescence in situ hybridization (FISH) using PY3.4, X alpha satellite, and SRY probes was performed in each case to analyze the sex chromosome translocation and gene translocation. SRY gene was amplified by polymerase chain reaction (PCR) and its mutation was detected by direct sequencing. The results showed that among 8 patients, 5 were positive for SRY and the remaining negative for SRY. In the patients positive for SRY genes, 3 presented testes and the left 2 streak ovaries. In the patients negative for SRY, only one case presented testes, while 2 ovaries. Direct sequencing demonstrated that all SRY genes were normal in the patients positive for SRY genes. FISH technique demonstrated that SRY genes translocated from Ypter to Xpter in 2 46,XX phenotypic males positive for SRY genes. It was concluded that SRY gene is strongly involved in male sex determination, while a sequence of other genes may be taken into account in sexual development.展开更多
46,XX男性综合征是一类罕见的性发育障碍性疾病,通常染色体为46,XX且Y染色体性别决定区(sex-determining region Y gene,SRY)阳性,有正常的外生殖器和男性表型,多因成年后不育就诊。而SRY阴性的46,XX男性综合征患者多伴发外生殖器发育畸...46,XX男性综合征是一类罕见的性发育障碍性疾病,通常染色体为46,XX且Y染色体性别决定区(sex-determining region Y gene,SRY)阳性,有正常的外生殖器和男性表型,多因成年后不育就诊。而SRY阴性的46,XX男性综合征患者多伴发外生殖器发育畸形,多因年幼时性发育异常就诊。报告1例SRY阴性的46,XX男性综合征患者,该患者外生殖器及第二性征发育均为正常男性型,检查发现患者核型为46,XX、SRY阴性、AZF区域缺失、高促性腺激素性性腺功能减退症且无精子症,其生育建议行供精人工授精。展开更多
性发育异常在人类遗传性疾病中很常见,因此性别决定在临床和生物学研究中非常重要。Y染色体性别决定区(sex-determining region of Y-chromosome,Sry)即哺乳动物Y染色体上的睾丸决定基因片段,与性别决定密切相关。本文对Sry基因的结构...性发育异常在人类遗传性疾病中很常见,因此性别决定在临床和生物学研究中非常重要。Y染色体性别决定区(sex-determining region of Y-chromosome,Sry)即哺乳动物Y染色体上的睾丸决定基因片段,与性别决定密切相关。本文对Sry基因的结构功能和表达调节及其相关的性别决定分子机制进行了综述。展开更多
