From OMIMHutchinson-Gilford progeria syndrome is a rare disorder characterized by short stature, low body weight, early loss of hair, lipodystrophy, scleroderma, decreased joint mobility, osteolysis, and facial features that resemble aged persons. Cardiovascular compromise leads to early death. Cognitive development is normal. Onset is usually within the first year of life (review by Hennekam, 2006). The designation Hutchinson-Gilford progeria syndrome appears to have been first used by DeBusk (1972).
A subset of patients with heterozygous mutations in the LMNA gene and a phenotype similar to HGPS have shown onset of the disorder in late childhood or in the early teenage years, and have longer survival than observed in classic HGPS (Chen et al., 2003; Hegele, 2003).
Other disorders with a less severe, but overlapping phenotype include mandibuloacral dysplasia (MADA; 248370), an autosomal disorder caused by homozygous or compound heterozygous mutations in the LMNA gene, dilated cardiomyopathy with hypergonadotropic hypogonadism (212112), caused by heterozygous mutation in the LMNA gene, and Werner syndrome (277700), an autosomal recessive progeroid syndrome caused by homozygous or compound heterozygous mutations in the RECQL2 gene (604611).
http://www.omim.org/entry/176670 From MedlinePlus GeneticsHutchinson-Gilford progeria syndrome is a genetic condition characterized by the dramatic, rapid appearance of aging beginning in childhood. Affected children typically look normal at birth and in early infancy, but then grow more slowly than other children and do not gain weight at the expected rate (failure to thrive). They develop a characteristic facial appearance including prominent eyes, a thin nose with a beaked tip, thin lips, a small chin, and protruding ears. Hutchinson-Gilford progeria syndrome also causes hair loss (alopecia), aged-looking skin, joint abnormalities, and a loss of fat under the skin (subcutaneous fat). This condition does not affect intellectual development or the development of motor skills such as sitting, standing, and walking.
People with Hutchinson-Gilford progeria syndrome experience severe hardening of the arteries (arteriosclerosis) beginning in childhood. This condition greatly increases the chances of having a heart attack or stroke at a young age. These serious complications can worsen over time and are life-threatening for affected individuals.
