Postnatal Blood Test
Assists in diagnostic evaluation of intellectual disability
Affymetrix_CytoScanDX_GroupBoxjpgThe CytoScan Dx assay from Affymetrix, Santa Clara, Calif, is a chromosomal microarray test to aid physicians in the diagnostic evaluation of congenital abnormalities, developmental delay, dysmorphic features, and intellectual disability in children. Including 2.69 million functional markers across the entire genome, the assay is intended for postnatal detection of chromosomal copy number variants in genomic DNA obtained from peripheral whole blood of patients referred for chromosomal testing based on clinical presentation. Equipped with both copy number and single-nucleotide polymorphism probes, the test can elucidate allelic imbalances and identify loss of heterozygosity and absence of heterozygosity associated with uniparental disomy or consanguinity, two conditions that increase the risk of recessive disorders. The assay also improves diagnostic yield by an incremental 12.5%, producing more accurate diagnosis when compared to G-banded karyotype. The assay can be analyzed using the company’s chromosome analysis suite Dx software, which offers an intuitive graphical interface.
