The XIST/CCPX FISH Probe Kit is designed to detect the human XIST gene located on chromosome band Xq13.2, along with the number of chromosome X copies per cell.
Rearrangements in the XIST gene region – also known as SXI1, swd66, DXS1089, DXS399E, LINC00001 or NCRNA00001 – have been observed in a number of familial and other conditions.
