chromosome 4 (written as 4p-). The size of the deletion varies among affected people, and studies suggest that larger deletions tend to result in more severe features. Most cases of WHS are not inherited, but some cases are inherited from an unaffected parent.Wolf-Hirschhorn syndrome (WHS) is a genetic condition that affects many parts of the body. The major features include a characteristic facial appearance; delayed growth and development; intellectual disability; low muscle tone (hypotonia); and seizures. Other features may include skeletal abnormalities, congenital heart defects, hearing loss, urinary tract malformations, and/or structural brain abnormalities. WHS is caused by a missing piece (deletion) of genetic material near the end of the short (p) arm of
