What is Werner syndrome?
General Discussion. Werner syndrome is a rare progressive disorder that is characterized by the appearance of unusually accelerated aging (progeria). Although the disorder is typically recognized by the third or fourth decades of life, certain characteristic findings are present beginning during adolescence and early adulthood.
When is Werner syndrome diagnosed?
Diagnosis. In some cases, Werner syndrome may be recognized clinically as early as approximately age 15, based upon a thorough clinical evaluation, characteristic physical findings (e.g., absence of growth spurt at puberty, short stature, low weight), and a careful patient and family history.
Why does Werner syndrome cause hair loss?
According to reports in the medical literature, the hair loss seen in those with Werner syndrome may occur secondary to impaired functioning of the ovaries in females or the testes in males (hypogonadism), an endocrine condition associated with deficient growth and sexual development.
How many cases of Werner syndrome have been reported?
Since the disorder was originally described in the medical literature in 1904 (O. Werner), more than 800 cases have been reported.
What is recessive genetic disorder?
Recessive genetic disorders occur when an individual inherits an abnormal gene from each parent. If an individual receives one normal gene and one abnormal gene for the disease, the person will be a carrier for the disease, but usually will not show symptoms.
Is Werner syndrome a recessive trait?
Werner syndrome is transmitted as an autosomal recessive trait. Human traits, including the classic genetic diseases, are the product of the interaction of two genes, one received from the father and one from the mother. Recessive genetic disorders occur when an individual inherits an abnormal gene from each parent.
Can Werner syndrome be related to blood?
The parents of some individuals with Werner syndrome have been closely related by blood (consanguineous). In these cases, if both parents carry the same disease gene, there is a higher-than-normal risk that their children may inherit the two disease genes necessary for the development of the disease.
The WRN Gene
The gene that causes Werner syndrome—the WRN gene—controls Werner protein production. This protein is thought to have a role in DNA repair and maintenance. A mutation in this gene can cause Werner syndrome. Experts believe the damage causes Werner syndrome symptoms, but they are unsure of exactly how it occurs. 1
Werner Syndrome Symptoms
A person with Werner syndrome will exhibit signs of premature aging such as:
Causes
Werner syndrome is an inherited condition, meaning a person is born with it. A person must inherit the mutated WRN gene from both parents for Werner syndrome to occur.
Diagnosis
Unlike progeria, Werner syndrome is not diagnosed at birth. That's why it is referred to as progeria of adults. It's usually diagnosed in a person’s 30s or 40s but can be diagnosed as early as age 15.
Treatment
There is no treatment for Werner syndrome. The focus is on managing symptoms and monitoring for complications such as tumors, heart disease, and diabetes.
Prognosis
People with Werner syndrome are at higher risk for cancer and cardiovascular disease. Heart disease occurs because of the loss of elasticity and thickening of the arteries.
Coping
People with Werner syndrome can manage their symptoms and avoid health complications with the help of a team of specialists.
What is Werner syndrome?
Werner syndrome is characterized by the premature appearance of features associated with normal aging and cancer predisposition. Individuals with Werner syndrome develop normally until the end of the first decade. The first sign is the lack of a growth spurt during the early teen years.
How many cardinal signs are there in Werner syndrome?
The clinical diagnosis of Werner syndrome is establishedin a probandwho has all four cardinal signs and two additional signs (definite) or the first three cardinal signs and two additional signs (probable).
Is Werner syndrome inherited?
Werner syndrome is inherited in an autosomal recessivemanner. At conception, each sib of an affectedindividual has a 25% chance of being affected, a 50% chance of being an asymptomatic carrier, and a 25% chance of being neither affected nor a carrier.
Does Werner syndrome affect the long bones?
The osteoporosis of individuals with Werner syndrome is unusual in that it preferentially affects the long bones [Mori et al 2021]. In contrast, osteoporosis during normative aging preferentially involves the vertebral bodies, particularly in women.

Werner syndrome is estimated to affect 1 in 200,000 individuals in the United States. This syndrome occurs more often in Japan, affecting 1 in 20,000 to 1 in 40,000 people.
Why do people with Werner's syndrome have thin arms and legs?
Many people with Werner syndrome have thin arms and legs and a thick trunk due to abnormal fat deposition. As Werner syndrome progresses, affected individuals may develop disorders of aging early in life, such as cloudy lenses ( cataracts) in both eyes, skin ulcers, type 2 diabetes, diminished fertility, severe hardening of the arteries ...
What is the function of the WRN gene?
This protein also assists in the process of copying (replicating) DNA in preparation for cell division. Mutations in the WRN gene often lead to the production of an abnormally short, nonfunctional Werner protein.
Why does Werner protein cause growth problems?
Cells with an altered Werner protein may divide more slowly or stop dividing earlier than normal , causing growth problems. Also, the altered protein may allow DNA damage to accumulate, which could impair normal cell activities and cause the health problems associated with this condition.
What is the name of the disorder that causes a person to have a short stature?
Werner syndrome is characterized by the dramatic, rapid appearance of features associated with normal aging. Individuals with this disorder typically grow and develop normally until they reach puberty. Affected teenagers usually do not have a growth spurt, resulting in short stature. The characteristic aged appearance of individuals with Werner syndrome typically begins to develop when they are in their twenties and includes graying and loss of hair; a hoarse voice; and thin, hardened skin. They may also have a facial appearance described as "bird-like." Many people with Werner syndrome have thin arms and legs and a thick trunk due to abnormal fat deposition.
Does Werner syndrome cause short stature?
Affected teenagers usually do not have a growth spurt, resulting in short stature. The characteristic aged appearance of individuals with Werner syndrome typically begins to develop when they are in their twenties and includes graying and loss of hair; a hoarse voice; and thin, hardened skin.
Is Werner syndrome autosomal recessive?
Expand Section. Werner syndrome is inherited in an autosomal recessive pattern, which means both copies of the WRN gene in each cell have mutations. The parents of an individual with Werner syndrome each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition.
What are the causes of Werner syndrome?
Mutations in the WRN gene cause Werner syndrome. The WRN gene provides instructions for producing the Werner protein, which is thought to perform several tasks related to the maintenance and repair of DNA. This protein also assists in the process of copying (replicating) DNA in preparation for cell division. Mutations in the WRN gene often lead to the production of an abnormally short, nonfunctional Werner protein. Research suggests that this shortened protein is not transported to the cell’s nucleus, where it normally interacts with DNA. Evidence also suggests that the altered protein is broken down more quickly in the cell than the normal Werner protein. Researchers do not fully understand how WRN mutations cause the signs and symptoms of Werner syndrome. Cells with an altered Werner protein may divide more slowly or stop dividing earlier than normal, causing growth problems. Also, the altered protein may allow DNA damage to accumulate, which could impair normal cell activities and cause the health problems associated with this condition.
When does Werner syndrome start?
The signs and symptoms of Werner syndrome do not usually appear until the teens. This first sign may be slower than normal growth during puberty. In the 20s-30s, other signs of early aging appear. Some of the signs and symptoms of Werner syndrome include 3):
Is Werner syndrome inherited?
Werner syndrome is inherited in an autosomal recessive pattern, which means both copies of the WRN gene in each cell have mutations. The parents of an individual with Werner syndrome each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition.
Werner syndrome: adult progeria
We call Werner syndrome a disorder or disease of genetic origin which is characterized by causing those who suffer from it premature and extremely accelerated aging , which begins to occur in the adult stage (from the twenty or thirty, although there is a majority tendency that begins to be observed at the end of the third decade of life or at the beginning of the fourth).
Possible prodrome
Werner syndrome is a disorder that as a general rule, it does not begin to express itself until adulthood .
Causes of this syndrome
Werner syndrome is a genetic disorder of an autosomal recessive nature. This implies that the origin of this disease is found in genetics , being also congenital and hereditary.
Treatment
Werner syndrome is a very rare condition, having received relatively little attention so far from the scientific community. Being also a disorder of genetic type, there is currently no treatment to cure this condition.
