Wolf-Hirschhorn syndrome is a multiple malformation syndrome characterised by severe growth deficiency, severe to profound mental retardation with the onset of convulsions in early infancy, microcephaly, sacral dimples and a characteristic face ('Greek helmet appearance')1,2.
The phenotype results from the partial deletion of the short arm of chromosome 4 (4p16.3). Molecular analyses of patients with small terminal and interstitial deletions have allowed the definition of the Wolf-Hirschhorn Critical Region, which is 165kb in size and lies between D4S166 and D4S33273.
The quality of the products we have received from Cytocell have been excellent. The FISH probes they provide to us give intense, strong signals and are a pleasure to count. What has really stood out however has been the level of support and assistance provided by Cytocell’s application specialists. The team worked very closely alongside our own during the adoption of this product and spent many hours with us perfecting the technique, going above and beyond what I would expect during the transition period. Source BioScience absolutely demand high quality products and service to be able to deliver our results with confidence, and that is what we have received from Cytocell.
