Abstract
A case of Turner's syndrome was found to be 46,XXqi/47XX,qi Xp-, a new mosaic. The origin of such a mosaic, the formation of the Xq isochromosome using the C-banding technique, and the X chromosome inactivation are discussed. The Xq isochromosome was apparently monocentric, but probably with two strictly close centromeres. The inactivated X seemed to be the Xqi or the normal X alternatively.
摘要
发现一例特纳综合征患者为46,XXqi/47XX,qi Xp-，这是一种新的嵌合体。本文讨论了这种嵌合体的起源、利用C带技术形成Xq等臂染色体以及X染色体失活的情况。Xq等臂染色体显然是单中心的，但可能有两个紧密相邻的着丝粒。失活的X染色体似乎交替为Xqi或正常的X染色体。
