Synonym(s): Hutchinson-Gilford disease. [pro- + G. gēras, old age]progeria Premature ageing. There are two types: Hutchinson-Gilford syndrome and Werner's syndrome. In the former, a child of 10 may show all the characteristics of old age-baldness, grey hair, wrinkled skin, loss of body fat and degenerative diseases of the arteries. In the latter, the disease starts in adult life and runs a rapid course over about 10 years. Both types are now believed to result from single spontaneous gene mutations. In HG syndrome the mutation is in the gene coding for lamin A, an important structural protein. In Werner's syndrome the mutation is in a helicase-a gene that unwinds double-strand DNA into two single strands.
