單體性(染色體)

Monosomy and srisomy are the conditions in which one or three homologs occur respectively, instead of the normal two. 單染色體以及三染色體都是正常的染色體缺失或增加一條染色體造成的。

RESULTS: Monosomy 22 was the predominant finding, detected in 47% of meningiomas. 結果：突出的發(fā)現是單體22可在47%25的腦膜瘤中檢測出來。

Turner syndrome encompasses several chromosomal abnormalities, of which monosomy X is the most common. 什么是'特納氏綜合征-染色體條件不足，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. 在單體22病例中，35%25的腫瘤中（49例中有17例）沒有檢測到多余的NF2突變。

Chromosomal analysis demonstrated mosaicism of monosomy 21 in peripheral blood lymphocyte: 45,XY,-21[7]/46,XY,[93]. 細胞染色體檢查顯示為鑲崁型單套第21染體，45,XY,-21[7]/46,XY,[93]。
