Infinium Global Screening Array with Cytogenetics-24

Detect structural variation in the human genome and examine cytogenomic changes in constitutional diseases and cancers with this research microarray.

Overview

The Infinium Global Screening Array-24 with Cytogenetics-24 contains approximately 700K variants, including 80K supplemental probes targeting more than 4800 tiered genes and regions with known disease associations. Target variants were selected based on the input from a cytogenetics research consortium and include genes defined by ClinGen as pathogenic and likely pathogenic along with an enhanced backbone for a modern, up-to-date assay.

  • Detect structural variation in the human genome, including duplications, deletions, amplifications, copy-neutral loss of heterozygosity, and mosaicism

  • Examine cytogenomic changes in constitutional diseases, cancers, and more

  • Process sample types including saliva, blood, and buccal swabs using the polymerase chain reaction (PCR)-free Infinium HTS Assay with only 200 ng DNA per sample

  • Analyze formalin-fixed paraffin-embedded (FFPE) paired tumor-normal samples when used with the appropriate FFPE cluster file

Broad clinical research applications

Markers were selected from clinical research databases, including ClinVar, CPIC, and PharmGKB for research applications, including risk profiling, pharmacogenomics, wellness characterization, and disease discovery.
