Wolf-Hirschhorn syndrome (WHS) is a condition that results when there is a deletion on the short arm of chromosome 4. This missing genetic material results in severe developmental delays and seizures. It is associated with variety of birth defects including microcephaly (small head size), cranial asymmetry, heart defects, curvature of the spine and cleft lip and/or palate.
Prognosis depends on what birth defects are present. It is estimated that around 35% of WHS patients die within the first two years of life. Children with WHS often exhibit severe to profound cognitive and physical disabilities.
