How many cases of progeria are in the world?
This condition is also known as Hutchinson-Gilford Progeria Syndrome. It is an extremely rare disease affecting only 1 out of 8 million births. Currently, there are only 80 known cases of progeria globally. In one year, a progeria patient typically ages as much as a normal person does in 10 years.
How fast does a person with progeria age?
Progeria, also known as Hutchinson-Gilford progeria syndrome (HGPS), is a rare genetic condition that causes a child's body to age fast. Most kids with progeria do not live past age 13. The disease affects both sexes and all races equally.
How does progeria cause heart disease?
Telomeres are proteins that play a major role in cellular aging. Children with Progeria are genetically predisposed to premature, progressive heart disease. Death occurs almost exclusively due to widespread heart disease, the leading cause of death worldwide. + Thus, there is clearly a tremendous need for research in Progeria.
How can you catch progeria?
Progeria is usually detected in infancy or early childhood, often at regular checkups, when a baby first shows the characteristic signs of premature aging. If you notice changes in your child that could be signs and symptoms of progeria, or you have any concerns about your child's growth or development, make an appointment with your child's doctor.
Why is progeria not inherited?
Progeria is caused by a genetic variant in the LMNA gene. This variant usually arises as a new change in the genetic material and is not inherited from a parent. Diagnosis is based on the symptoms, clinical exam, and may be confirmed by the results of genetic testing.

A mutation in the LMNA gene causes progeria. Most kids with progeria don't live past age 13. The disease affects people of all sexes and races equally. About 1 in every 4 million babies are born with it worldwide.
Could progeria have been prevented?
There's no cure for progeria, but regular monitoring for heart and blood vessel (cardiovascular) disease may help with managing your child's condition. During medical visits, your child's weight and height is measured and plotted on a chart of normal growth values.
How is progeria passed on?
Inheritance. Hutchinson-Gilford progeria syndrome is considered an autosomal dominant condition, which means one copy of the altered gene in each cell is sufficient to cause the disorder.
Is progeria detected before birth?
Children with progeria do not begin showing symptoms until around 18-24 months; typically they are born looking healthy.
What causes progeria in pregnancy?
The Progeria gene discovery revealed that Progeria is caused by a mutation in the gene called LMNA (pronounced “lamin-A”). The LMNA gene produces the lamin A protein, which is part of the structural scaffolding that holds the nucleus of a cell together and helps to keep cells healthy.

How to help a child with progeria?
At home. Kids with progeria are more likely to get dehydrated, so they need to drink plenty of water , especially when they're sick or it's hot. Small meals more often can help them eat enough, too. Cushioned shoes or inserts can ease discomfort and encourage your child to play and stay active.
What are the symptoms of progeria?
A high-pitched voice. Loss of body fat and muscle. Hair loss, including eyelashes and eyebrows. Thin, wrinkled skin that shows spots.

Can a pediatrician diagnose progeria?
If your pediatrician is concerned, you may need to see a specialist in medical genetics who can confirm the diagnosis with a blood test. Before the genetic blood tests were availables, doctors could only diagnose progeria with X-rays and observation. Progeria Treatments.
What is the cause of progeria?
Progeria is caused by a change (mutation) in the LMNA gene that codes for the lamin A protein. The lamin A protein is the scaffolding that holds the nucleus of a cell together. Researchers now believe that the defective lamin A protein makes the nucleus unstable.

The disorder was originally described in the medical literature in 1886 (J. Hutchinson) and 1897 (H. Gilford). The prevalence of HGPS is approximately 1 in 20 million, so at any given time, there are approximately 400 children ...
When is HGPS diagnosed?
HGPS is usually diagnosed during the second year of life or later, when progeroid features begin to be noticeable . The diagnosis is based upon a thorough clinical evaluation, characteristic physical findings, a careful patient history and diagnostic genetic testing which is available through the Progeria Research Foundation ( www.progeriaresearch.org ). More rarely, the disorder may be suspected at birth based upon recognition of certain suspicious findings (e.g., “scleroderma-like” skin over the buttocks, thighs, lower abdomen; midfacial cyanosis; “sculptured” nose).
Does HGPS cause aging?
Some researchers suspect that reduced activity of certain enzymes may play a role in causing accelerated aging in individuals with HGPS. In one study, skin cells (fibroblasts) obtained from individuals with progeria were compared with skin cells from individuals without the disease.
Is Zokinvy effective for progeria?
Previously, in September 2012, the results of the first-ever clinical drug trial for children with progeria showed that Zokinvy was effective for progeria. Every child showed improvement in one or more of four ways: gaining additional weight, better hearing, improved bone structure and/or, most importantly, increased flexibility of blood vessels.
Can you have a child with progeria?
For parents who have already had a child with progeria, the chance of having another affected child is much higher – about 2-3%. This is due to a condition called mosaicism, where a parent has the genetic mutation for progeria in a small proportion of their cells, but does not have progeria.

Where does the word "progeria" come from?
The word progeria comes from the Greek words "pro" ( πρό ), meaning "before" or "premature", and "gēras" ( γῆρας ), meaning "old age".
Who first described progeria?
Progeria was first described in 1886 by Jonathan Hutchinson. It was also described independently in 1897 by Hastings Gilford. The condition was later named Hutchinson–Gilford progeria syndrome. Scientists are interested in progeria partly because it might reveal clues about the normal process of aging.
What is the FTI for progeria?
Farnesyltransferase inhibitors (FTIs) are drugs that inhibit the activity of an enzyme needed to make a link between progerin proteins and farnesyl groups. This link generates the permanent attachment of the progerin to the nuclear rim. In progeria, cellular damage can occur because that attachment occurs, and the nucleus is not in a normal state. Lonafarnib is an FTI, which means it can avoid this link, so progerin can not remain attached to the nucleus rim, and it now has a more normal state.

How early can you tell if you have progeria?
Signs and symptoms. Children with progeria usually develop the first symptoms during their first few months of life. The earliest symptoms may include a failure to thrive and a localized scleroderma -like skin condition. As a child ages past infancy, additional conditions become apparent, usually around 18–24 months.
