Adult progeria, formally known as Werner syndrome (WS), is a rare genetic disorder that causes the body’s cells to age much faster than normal. People with WS typically develop normally until puberty, after which they fail to have the normal adolescent growth spurt and begin to exhibit features commonly associated with elderly individuals—such as graying hair, thinning skin, and cataracts—often in their twenties or thirties rarediseases.info.nih.goven.wikipedia.org. WS is inherited in an autosomal recessive pattern, meaning an affected individual carries two copies of a mutated WRN gene, one from each parent rarediseases.info.nih.gov. The WRN gene encodes a DNA helicase important for repairing double-strand DNA breaks; when it is defective, cells accumulate damage more rapidly, leading to premature cellular aging en.wikipedia.org.
Adult progeria, medically known as Werner syndrome, is a rare autosomal recessive disorder characterized by the premature appearance of aging symptoms, typically manifesting in the third to fourth decade of life. It results from mutations in the WRN gene, which encodes a RecQ helicase involved in DNA repair, replication, and telomere maintenance. Patients exhibit clinical features such as early-onset greying and thinning of hair, scleroderma-like skin changes, bilateral cataracts, type 2 diabetes mellitus, atherosclerosis, osteoporosis, and an increased risk of malignancies. Accelerated cellular senescence, genomic instability, and defective DNA repair underlie the multisystem degeneration seen in Werner syndrome physio-pedia.comen.wikipedia.org.
Types
Classical Werner Syndrome
Classical WS is caused by mutations in the WRN gene on chromosome 8. These mutations truncate or destabilize the Werner protein (WRNp), impairing its helicase and exonuclease functions that normally help maintain DNA integrity rarediseases.info.nih.govpmc.ncbi.nlm.nih.gov. Onset is usually in the late teens or early twenties, with patients developing short stature, skin atrophy, cataracts, and age-related diseases such as diabetes and atherosclerosis.
Atypical Werner Syndrome
Atypical WS refers to individuals who meet clinical criteria for WS but lack WRN gene mutations. Some atypical cases are linked to LMNA gene mutations (the same gene mutated in Hutchinson-Gilford progeria), while others have unknown genetic causes rarediseases.info.nih.govega-archive.org. Clinically, these patients display similar premature aging features but may vary in age of onset, progression, and severity.
