The major features of this disorder include a characteristic facial features, delayed growth and development, intellectual disability, and seizures. Almost everyone with this disorder has distinctive facial features, including a broad nasal bridge, large and protruding eyes, and a high forehead.  This combination is described as a 'Greek warrior helmet' appearance. Other characteristic facial features include a shortened distance between the nose and upper lip (a short philtrum), a downturned mouth, a small chin (micrognathia), and poorly formed ears with small holes (pits) or flaps of skin (tags). Additionally, affected individuals may have asymmetrical facial features and an unusually small head (microcephaly). People with Wolf-Hirschhorn syndrome experience delayed growth and development. Slow growth begins before birth, and affected infants tend to have problems feeding and gaining weight (failure to thrive). They also have weak muscle tone (hypotonia) and underdeveloped muscles. Motor skills such as sitting, standing, and walking are significantly delayed. Most children and adults with this disorder also have short stature. Intellectual disability ranges from mild to severe in people with Wolf-Hirschhorn syndrome. Compared to people with other forms of intellectual disability, their socialization skills are strong, but verbal communication and language skills tend to be weaker. Most affected children also have seizures, which may be resistant to treatment. Seizures tend to disappear with age. Additional features of Wolf-Hirschhorn syndrome include skin changes, such as mottled or dry skin; skeletal abnormalities, such as abnormal curvature of the spine (scoliosis and kyphosis); dental problems including, missing teeth; and an opening in the roof of the mouth (cleft palate) and/or a split in the upper lip (cleft lip). Wolf-Hirschhorn syndrome can also cause abnormalities of the eyes, heart, and genitourinary tract. A condition called Pitt-Rogers-Danks syndrome has features that overlap with those of Wolf-Hirschhorn syndrome.
