Using high-resolution array-CGH, we identified unique duplications of a region on 6q27 in four multiplex families with at least three cases of chordoma, a cancer of presumed notochordal origin. The duplicated region contains only the T (brachyury) gene, which is important in notochord development and is expressed in most sporadic chordomas. Our findings highlight the value of screening for complex genomic rearrangements in searches for cancer-susceptibility genes.
利用高分辨率阵列比较基因组杂交技术,我们在四个至少有三例脊索瘤(一种推测起源于脊索的癌症)的多重家庭中,鉴定出了6q27区域的独特重复。该重复区域仅包含T(短尾)基因,该基因在脊索发育中起重要作用,并且在大多数散发性脊索瘤中表达。我们的研究结果突出了在寻找癌症易感基因时筛查复杂基因组重排的价值。
