单体性(染色体)

Monosomy and srisomy are the conditions in which one or three homologs occur respectively, instead of the normal two. 单染色体以及三染色体都是正常的染色体缺失或增加一条染色体造成的。

RESULTS: Monosomy 22 was the predominant finding, detected in 47% of meningiomas. 结果：突出的发现是单体22可在47%25的脑膜瘤中检测出来。

Turner syndrome encompasses several chromosomal abnormalities, of which monosomy X is the most common. 什么是'特纳氏综合征-染色体条件不足，造成女性性特征'?

Among the monosomy 22 cases, no additional NF2 mutations could be identified in 35% (17 out of 49) of tumors. 在单体22病例中，35%25的肿瘤中（49例中有17例）没有检测到多余的NF2突变。

Chromosomal analysis demonstrated mosaicism of monosomy 21 in peripheral blood lymphocyte: 45,XY,-21[7]/46,XY,[93]. 细胞染色体检查显示为镶崁型单套第21染体，45,XY,-21[7]/46,XY,[93]。
