はじめに：CNV解析
コピー数多型（CNV）とは、1つ以上の遺伝子のコピー数が異常になるゲノムの変化をいいます。重複、欠失、転座、逆位などの構造ゲノム再編がCNVを引き起こす場合があります。
一塩基多型（SNP）のように、疾患感受性との関連が指摘されるCNVもあります。イルミナはさまざまなアレイおよび次世代シーケンス（NGS）ソリューションを提供して、高解像度なコピー数解析を実現します。
Array-Based CNV Analysis
Genome-wide genotyping arrays are commonly used to detect genetic variants, including CNVs that contribute to diseases and phenotypes. Array-based approaches for copy number analysis offer reliable, efficient methods for large-scale analysis.
Researchers can process multiple samples on a single microarray for broad surveys of genomic structural variation, and accurately profile chromosomal aberrations such as amplifications, deletions, rearrangements, and copy-neutral loss of heterozygosity.
CNV Array Products
Illumina offers both human and non-human genotyping arrays for CNV analysis. Illumina scientists strategically select the markers on the arrays to provide maximum genome coverage for optimal copy number analysis.

Learn MoreCustom genotyping arrays

Learn MoreCopy Number Analysis with NGS
While efficient for large CNV detection, genotyping arrays are less sensitive for detecting CNVs smaller than 50 kilobases. By providing a base-by-base view of the genome, NGS detects small or novel copy number variants that arrays often miss.
NGS can also map the exact location of a CNV. The high resolution of sequencing complements the high throughput of arrays, enabling a comprehensive view of the genome.

Learn MoreStudying Downstream Effects of CNVs
Copy number variation often alters gene expression. Targeted RNA sequencing (RNA-Seq) is an unbiased approach for analyzing and quantifying transcripts of interest. RNA-Seq can capture subtle gene expression changes, measure allele-specific expression, and detect fusion genes. By characterizing the downstream effects of variants, researchers can better understand the molecular mechanisms of disease. Learn more about targeted RNA-Seq.
