摘要 微阵列比较基因组杂交技术(array-based comparative genomic hybridization,array-CGH)结合了比较基因组杂交技术(CGH)、微阵列芯片技术(micro-array)的优势,在分子遗传学中广泛应用于全基因组水平的拷贝数分析。array-CGH在产前诊断染色体疾病中的应用相比于传统的细胞遗传学核型分析技术以及荧光原位杂交技术(FISH)、多重荧光定量PCR(QF-PCR)、多重连接探针扩增技术(MLPA)等分子遗传学技术具有高通量、高分辨、高灵敏度、操作自动化等优势;能够检测出相当一部分常规核型分析技术不易发现的染色体微缺失和微重复综合征,以及亚端粒或者其他不平衡的染色体重排。目前用array-CGH进行全基因组扫描进行产前诊断,判断和评估所检出的拷贝数变异(CNVs)的临床意义有一定难度。对不同位点CNVs出现频率及临床意义研究可能会是近期研究热点之一。
