Concordance between single-nucleotide polymorphism–based genomic instability assays and a next-generation sequencing-based homologous recombination deficiency test

We evaluated the performance of single-nucleotide polymorphism (SNP) genotyping arrays OncoScan (Thermo Fisher Scientific, San Diego, CA) and Infinium CytoSNP-850K (CytoSNP; Illumina, Waltham, MA) for assessing homologous recombination deficiency (HRD) genomic instability.
