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.
