Summary Summary

Werner syndrome is a condition that causes premature aging. People with this syndrome will develop and grow normally until puberty. At puberty, growth stops and adults with Werner syndrome are typically shorter than average. By the early 20s-30s, people with this syndrome develop conditions usually associated with more advanced ages. In addition, people with Werner syndrome have an increased risk of developing cancer, especially thyroid and skin cancers. Heart attack and cancer are the most common causes of death. Werner syndrome is caused by mutations in the WRN gene and is inherited in an autosomal recessive manner. This condition is diagnosed based on the symptoms and genetic testing. Treatment is based on individual symptoms and focuses on prevention of heart disease and cancer.^[1]^[2]^[3]^[4]

Symptoms Symptoms

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:^[1]^[4]

• Shorter than average height as an adult
• Bilateral cataracts (clouding of the lens of both eyes )
• Premature graying and thinning of the hair on the head
• Skin changes (thinning of skin, fragile skin)
• Loss of fat under the skin
• Thin limbs
• Characteristic facial changes (pinched nose, narrow face)
• Voice changes
• Decreased functioning of the testes and ovaries
• Decreased fertility
• Open skin sores, especially on the ankles
• Narrowing and hardening of the arteries (atherosclerosis)
• Type 2 diabetes mellitus
• Thinning of the bones (osteoporosis)
• Cancer

Not everyone with Werner syndrome will have all of these symptoms.

Cause Cause

Werner syndrome is caused by a genetic change (mutation) in the WRN gene. This gene makes a protein that is involved with repairing damage to DNA and maintaining the structure of DNA.^[2]

Last updated: 2/21/2019

Inheritance Inheritance

Werner syndrome is inherited in an autosomal recessive pattern.^[1] All individuals inherit two copies of each gene. To have Werner syndrome, a person must have a mutation in both copies of the WRN gene in each cell. There is nothing either parent can do, before or during pregnancy, to cause a child to have this.

People with autosomal recessive conditions inherit one mutation from each of their parents. The parents, who each have one mutation, are known as carriers. Carriers of an autosomal recessive disorder typically do not have any signs or symptoms (they are unaffected). When two carriers of an autosomal recessive condition have children, each child has a:

25% (1 in 4) chance to have the disorder
50% (1 in 2) chance to be an unaffected carrier like each parent
25% (1 in 4) chance to be unaffected and not be a carrier

.

Last updated: 2/21/2019

Diagnosis Diagnosis

The diagnosis of Werner syndrome is made based on a clinical examination and the symptoms.^[4] Genetic testing looking for changes in the WRN gene is also helpful.

Last updated: 2/21/2019

Testing Resources

The Genetic Testing Registry (GTR) provides information about the genetic tests for this condition. The intended audience for the GTR is health care providers and researchers. Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional.

Treatment Treatment

There is no specific treatment for Werner syndrome. The treatment is based on managing the symptoms of the condition. Medications can be used to help manage diabetes and heart disease.^[1]

Last updated: 2/21/2019

Prognosis Prognosis

People with Werner syndrome develop conditions usually associated with advanced age in their 20s-30s. In general, people with Werner syndrome have a shorter than average life span. The most common causes of death are heart attack and cancer. Most people with this condition die in their late-40s to mid-50s, but this depends on how well the symptoms are managed and the presence of other health conditions.^[4]

Last updated: 2/21/2019

Statistics Statistics

In the United States, it is estimated that about 1 in 200,000 people has Werner syndrome. Worldwide, the prevalence is estimated to be 1 in 380,000 to 1 in 1,000,000.^[1]

NCATS Co-Sponsored Conferences

The Helicase and Nucleic Acid-based Machine Conference Sunday, July 21, 2019 - Friday, July 26, 2019
Location: The Steamboat Grand, Steamboat Springs, CO
Description: Malfunctions of helicases and nucleic acid-based machines are implicated in a number of rare genetic disorders. Specifically, hereditary mutations in helicase genes are linked to rare diseases including Werner Syndrome, Bloom’s Syndrome, Rothmund-Thomson Syndrome, Cockayne Syndrome, Xeroderma Pigmentosum, Trichothiodystrophy, Warsaw Breakage Syndrome, Fanconi Anemia, Dyskeratosis Congenita, Crohn’s Disease, Ophthalmoplegia, and others. This FASEB meeting, which was first held in 2001, examines the roles of these and related helicases in genome metabolism and rare diseases. The meeting is the only one of its kind to focus on the functions, interactions and structures of helicases and helicase-like motors as components of fundamentally important supramolecular machines, and it explores their regulation and key roles in uncommon genetic disorders characterized by defects in DNA repair and genomic stability. The conference brings together a diverse group of academic and industry scientists who focus on the functional roles of helicases and helicase-like motors in pathways of nucleic acid metabolism.
