Genomic copy number variation (CNV) is a recently identified form of global genetic variation in the human genome. The Affymetrix GeneChip 100 and 500 K SNP genotyping platforms were used to perform a large-scale population-based study of CNV frequency. We constructed a genomic map of 578 CNV regions, covering approximately 220 Mb (7.3%) of the human genome, identifying 183 previously unknown intervals. Copy number changes were observed to occur infrequently (<1%) in the majority (>93%) of these genomic regions, but encompass hundreds of genes and disease loci. This North American population-based map will be a useful resource for future genetic studies.
基因组拷贝数变异（CNV）是人类基因组中最近发现的一种全基因组遗传变异形式。使用Affymetrix GeneChip 100和500 K单核苷酸多态性（SNP）基因分型平台对CNV频率进行大规模人群研究。我们构建了一个包含578个CNV区域的基因组图谱，覆盖了约220兆碱基（占人类基因组的7.3%），识别出183个以前未知的区间。在这些基因组区域的大多数（>93%）中，拷贝数变化很少发生（<1%），但涉及数百个基因和疾病位点。这张基于北美人群的图谱将为未来的遗传学研究提供有用的资源。
