The clinical characteristics of Asian patients with classical-type Hutchinson–Gilford progeria syndrome

Hutchinson–gilford progeria syndrome (hgps) is an extremely rare genetic disorder that shows a characteristic progeria phenotype. we conducted a questionnaire survey of 1173 tertiary hospitals in japan and reviewed the academic reports, to identify the characteristics of asian patients with classical hgps. as a result, four japanese patients were identified; this was estimated to account for approximately two-third of the prevalence in japan. three asian patients who had definitively been diagnosed with classical hgps were identified in the literature; in total, the clinical characteristics of seven patients were evaluated. most of the clinical phenotypes of asian patients were essentially similar to those of patients of other ethnicities, such as sclerodermatous skin, growth failure, loss of scalp hair or severe complications of cardiovascular and cerebral ischemic disease. in conclusion, to circumvent or minimalize severe vascular complication, an early diagnosis, careful observation and, promisingly, new intervention with farnesylation inhibitors may improve the prognosis of classical hgps patients.
