脊索样脑膜瘤是一种罕见的组织学亚型脑膜瘤。对3例患者的细胞遗传学分析揭示了染色体显微解剖和反向荧光原位杂交确定的(1)t(1;3)(p12-13;q11)不平衡易位的独特特征。由于t(1;3)未在其他脑膜瘤亚型中观察到,因此它可能是脊索样脑膜瘤的特异性细胞遗传学标志物。目前尚不清楚是融合基因还是染色体臂1p和3p基因的联合丢失是易位的重要病理结果。中华医学杂志(英文版),1999。©1999 Wiley‐Liss, Inc。
Chordoid meningioma is a rare histological subtype of meningiomas. Cytogenetic analysis of three cases revealed the unique feature of an unbalanced translocation der(1)t(1;3)(p12–13;q11) that was ascertained by chromosome microdissection and reverse fluorescence in situ hybridization. As the t(1;3) has not been observed in other subtypes of meningioma, it may represent a specific cytogenetic marker of chordoid meningiomas. It is not yet clear whether a fusion gene or the combined loss of genes from chromosome arms 1p and 3p is the pathogenetically important outcome of the translocation.
