Hutchinson-Gilford progeria syndrome

Hutchinson - Guildford early syndrome is a hereditary disorder characterized by severe rapid aging from childhood. Infected children usually look normal at birth or early in infancy but then grow more slowly than other children and do not grow at the expected rate (they can not prosper). They have a distinctive facial appearance that includes a conspicuous eye, a thin nose with a sharp nose, thin lips, a small jaw, and a protruding ears. Hutchinson - Guildford Early Aging Syndrome may also cause hair loss (hair loss), aged skin, joint abnormalities and hypodermic fat reduction (subcutaneous fat). Such a situation does not affect mental development, development of athletic ability such as sitting, standing, walking.

Hutchinson - Guildford patients with premature aging syndrome experience severe arteriosclerosis (atherosclerosis) from childhood. Such a situation greatly enhances the possibility of a heart attack or stroke of young people. These serious complications worsen over time and cause life threatening to affected individuals.

Mutations in the LMNA gene result in Hutchinson-Guildford premature aging syndrome. The LMNA gene provides an illustration of the production of a protein called lamin A. This protein plays an important role in determining the shape of the nucleus within the cell. It is the basic scaffolding (supporting) component of the nuclear membrane, which is the membrane that surrounds the nucleus. Mutations leading to Hutchinson - Gilford premature aging syndrome result in the production of abnormal form of Lamin A protein. The altered protein renders the nuclear membrane unstable, gradually hurting the nucleus and makes it easier for cells to die prematurely. Researchers are working to determine how these changes will affect the characteristics of Hutchinson - Guildford Early Aging Syndrome.

Hutchinson - Guildford prematurity syndrome ("premature aging" or "HGPS") is a rare fatal hereditary disorder characterized by accelerated aging of children. That name comes from Greek and means "premature aging". Although premature aging * has various forms, the classic type is early disability syndrome of Hutchinson - Guildford named after a doctor who explained it first in the UK. HGPS is caused by a mutation in the gene called LMNA (pronounced Lamin a). The LMNA gene produces Lamin A protein, a structural scaffold that holds the nucleus together. Researchers now believe that defective lamin A protein will destabilize the nucleus. Cell instability seems to lead to a premature aging process

Hutchinson - Gilford Early Aging Syndrome is a rare autosomal genetic disorder that some tissues appear to experience accelerated aging. The patient seems normal at birth, but it develops representatives of early childhood, and dies in early adolescence. Hutchinson - Gilford The most common cause of premature aging syndrome is the neonatal mutation of the Lamin A / C gene (LMNA) that activates hidden splice sites that produce abnormal Lamin A protein called progerin. Accumulation of progerin leads to abnormal nuclear morphology in vitro and is thought to directly lead to disease phenotype. Recently, patients treated with rapamycin in patients with Hamilton - Guildford premature aging syndrome corrected nuclear morphologic defects, delayed the onset of cellular senescence, and enhanced progestin clearance by autophagy degradation.
