  Werner syndrome - Wikipedia, the free encyclopedia
For this reason, Werner syndrome is often referred to as a progeroid syndrome, as it partly mimics the symptoms of Progeria.
Werner syndrome is estimated to affect 1 in 200,000 individuals in the United States.
Werner syndrome is named after Otto Werner, a German student who described the syndrome as part of his doctoral thesis in 1904.

The characteristic features of Werner syndrome include short stature, premature graying and balding, wizened face, beaked nose, cataracts, scleroderma-like skin changes (especially in the extremities), subcutaneous calcification (deposits of calcium beneath the skin), premature arteriosclerosis, muscular atrophy and tendencies to diabetes mellitus and to tumors (especially, osteosarcoma and meningioma).

 Werner syndrome Information on Healthline
Werner syndrome is a very rare, inherited disease that resembles premature aging.
Werner was a medical student in 1903 when he first observed the syndrome in four siblings, all about 30 years of age.
For instance, the tumors commonly seen in Werner syndrome patients are commonly derived from the cells of the mesoderm, a middle layer of the embryo that gives rise to a variety of tissues including cartilage, muscle, bone, kidneys, and connective tissue.

 Progeria Information Database: Werner's Syndrome Symptoms   (Site not responding. Last check: 2007-10-09)
Concentrated primarily in the Japanese population for reasons as yet unknown, Werner’s syndrome (WS) is the most common of all recognized progeroid syndromes.
Werner is sometimes also called "adult onset progeria," because unlike most progeroid syndromes it manifests only after the onset of puberty.
In the case of Werner’s syndrome, these include but are not limited to hair graying and loss, the appearance of heavy skin wrinkles, muscle atrophy, osteoporosis, cataracts in the eyes, discontinued function of the reproductive organs, arteriosclerosis, and the onset of diabetes mellitus II.

 Werner syndrome
Werner syndrome is a premature aging disease that begins in adolescence or early adulthood and results in the appearance of old age by 30-40 years of age.
The gene for Werner disease (WRN) was mapped to chromosome 8 and cloned: by comparing its sequence to existing sequences in GenBank, it is a predicted helicase belonging to the RecQ family.
The molecular role of WRN in Werner syndrome therefore remains to be proven, as does any role it might have in the aging process in general.
