Werner syndrome refers to a rare and autosomal recessive genetic disorder that leads to accelerated ageing, characterised by the appearance of age-associated features such as greying hair, type 2 diabetes, cataracts, and osteoporosis beginning in adolescence or early adulthood. It occurs due to the mutations in the WRN gene, which is essential for DNA repair, resulting in genomic instability and significant increase in the risk of developing various types of cancer. Werner syndrome is also called Adult Progeria.
Werner syndrome refers to a genetic disorder. It happens due to the changes (mutations) in a WRN gene that make the gene not function correctly. People with Werner syndrome will see two mutations in the WRN gene, generally inheriting one from each parent.
Adult progeria, medically known as Werner syndrome, is a rare genetic disorder that causes premature ageing beginning in early adulthood. It affects approximately 1 in 1,000,000 people worldwide. Individuals with this condition experience age-related diseases and symptoms decades earlier than usual, significantly impacting their health and lifespan.
Early diagnosis of adult progeria symptoms is essential for better management and improved quality of life. Additionally, identifying these symptoms can help affected individuals seek timely medical care and support.

Werner syndrome is an autosomal recessive disorder, which means an individual must inherit the faulty gene from both parents to develop the condition. It is caused by mutations in the WRN gene (RECQL2), which encodes a protein vital for DNA repair, replication, and maintenance.
When the WRN protein is deficient or dysfunctional, cells experience genomic instability, leading to premature ageing and an increased risk of age-related diseases.
Werner syndrome impacts nearly every system in the body. The signs of ageing and deterioration typically become noticeable in early adulthood. Below is a breakdown of the most common symptoms:
Living with Werner syndrome can be physically and emotionally challenging. Here are the main ways it impacts daily life:
Hutchinson-Gilford Progeria Syndrome (HGPS) is a rare genetic condition that causes children to age rapidly, starting within the first few years of life. It is significantly rarer than Werner syndrome and progresses far more quickly. However, both conditions stem from errors in how cells organise their DNA and structure.
The following table outlines the key differences and similarities between Hutchinson-Gilford Progeria Syndrome (HGPS) and Werner Syndrome:
Aspects | Hutchinson-Gilford Progeria Syndrome (HGPS) | Werner Syndrome (Adult Progeria) |
Onset | Early childhood (1–2 years) | Adolescence or early adulthood (teens–20s) |
Gene Affected | LMNA mutation (leads to progerin buildup) | WRN gene mutation (impairs DNA repair) |
Lifespan | 13–15 years | 40–50 years |
Key Symptoms | Growth failure, thin skin, aged appearance, and cardiovascular disease | Cataracts, diabetes, osteoporosis, and cancer risk |
Mental Development | Normal but mild cognitive delays may occur | Normal |
Diagnosis is based on clinical evaluation, physical appearance, genetic testing, and family history. It may involve:
There is no cure for Werner syndrome. Treatment focuses on managing complications and improving quality of life, including:
Experimental therapies targeting DNA repair and ageing pathways are under study, but none are yet approved.
Werner syndrome causes premature ageing and the early onset of age-related diseases, typically beginning in early adulthood. Although it shares similarities with childhood progeria, it presents distinct genetic and clinical features. Early detection, palliative care, and emotional resilience are crucial for enhancing quality of life. Ongoing research into targeted therapies offers hope for the future.
