The XA TriScore (X/Y/21) enumeration probe is a qualitative, non-automated test for the detection of copy number variations of chromosome X, chromosome Y and chromosome 21 by fluorescence in situ hybridization (FISH). The product is intended for prenatal testing of pregnancies at risk for copy number variations of chromosomes X and chromosome Y and trisomy 21 on methanol/acetic-acid fixed uncultured amniocytes.
The XA TriScore (X/Y/21) enumeration probe consists of an aqua-labeled probe hybridizing to the centromere of the X-chromosome, a green-labeled probe hybridizing to the centromere of the Y-chromosome and an orange-labeled probe hybridizing to the DSCR4 gene region at 21q22.1-22.2.
Probe maps for selected products have been updated. These updates ensure a consistent presentation of all gaps larger than 10 kb including adjustments to markers, genes, and related elements. This update does not affect the device characteristics or product composition. Please refer to the list to find out which products now include updated probe maps.
Probe map details are based on UCSC Genome Browser GRCh37/hg19, with map components not to scale.
