Comprehensive Screening of Gene Copy Number Aberrations in Formalin-Fixed, Paraffin-Embedded Solid Tumors Using Molecular Inversion Probe–Based Single-Nucleotide Polymorphism Array

Gene copy number aberrations (CNAs) represent a major class of cancer-related genomic alterations that drive solid tumors. Comprehensive and sensitive detection of CNAs is challenging because of often low quality and quantity of DNA isolated from the formalin-fixed, paraffin-embedded (FFPE) solid tumor samples. Herein, in a clinical molecular diagnostic laboratory, we tested the utility and validated a molecular inversion probe-based (MIP) array to routinely screen for CNAs in solid tumors. Using low-input FFPE DNA, the array detects genome-wide CNAs with a special focus on 900 cancer-related genes.
