Question: What is (are) Werner's syndrome ?
Answer: Werner's syndrome is a disease chiefly characterized by premature aging and cancer predisposition. Development is typically normal until the end of the first decade; the first sign is the lack of a growth spurt during puberty. Early signs (usually in the 20s) include loss and graying of hair, hoarseness, and scleroderma-like skin changes, followed by cataracts, type 2 diabetes mellitus, hypogonadism, skin ulcers, and osteoporosis in the 30s. Myocardial infarction (heart attack) and cancer are the most common causes of death, which typically occurs in the late 40s. It is caused by mutations in the WRN gene and is inherited in an autosomal recessive manner. Management focuses on treatment of signs and symptoms and prevention of secondary complications.

Answer: What are the signs and symptoms of Werner's syndrome? The Human Phenotype Ontology provides the following list of signs and symptoms for Werner's syndrome. If the information is available, the table below includes how often the symptom is seen in people with this condition. You can use the MedlinePlus Medical Dictionary to look up the definitions for these medical terms.

Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature. The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common.
