Progeria

Progeria is a rare genetic condition that produces rapid aging in children.

Causes

Progeria is a rare condition that is remarkable because its symptoms strongly resemble normal human aging, but occur in young children.
Ninety percent of children with progeria have a mutation on the gene that encodes the protein lamin A. Progeria usually occurs without cause. It is only very rarely seen in more than one child in a family.

Symptoms

  • Growth failure during the first year of life
  • Narrow, shrunken or wrinkled face
  • Baldness
  • Loss of eyebrows and eyelashes
  • Short stature
  • Large head for size of face (macrocephaly)
  • Open soft spot (fontanelle)
  • Small jaw (micrognathia)
  • Dry, scaly, thin skin
  • Limited range of motion
  • Teeth - delayed or absent formation

Exams and Tests

The signs include:
  • Insulin-resistance
  • Skin changes similar to that seen in scleroderma (the connective tissue becomes tough and hardened)
Cardiac stress testing may reveal signs of early atherosclerosis of blood vessels.
Genetic testing can detect mutations in lamin A that cause progeria.

Treatment

There is presently no treatment for progeria.

Outlook (Prognosis)

Progeria is associated with a short lifespan. The average patient survives to the early teens. However, some patients can live into their early 20s. The cause of death is usually related to the heart or a stroke as a result of the progressive atherosclerosis.

Possible Complications

  • Heart attack (myocardial infarction)
  • Stroke

When to Contact a Medical Professional

Prevention

There is no known prevention.
