Hutchinson-Gilford Progeria Syndrome (HGPS)

Hutchinson-Gilford Progeria Syndrome (HGPS)

By JOHN FELIX S.N

Progeria, also known as Hutchinson-Gilford progeria syndrome (HGPS), is a rare, deadly, hereditary illness that manifests as early aging. Early infancy is typically when progeria children look normal. Affected children start to exhibit severe growth delays between the ages of nine and 24 months, which causes short stature and low weight. They also acquire a characteristic facial look that includes an excessively small face in relation to the head, a micrognathia (underdeveloped jaw), malformed and crowded teeth, abnormally large eyes, a small nose, and a slight blueness around the lips. Additionally, by the second year of life, the eyebrows, eyelashes, and scalp hair all fall out due to alopecia, and the scalp hair may be replaced by tiny, downy, white, or blond hair.

Generalized atherosclerosis, cardiovascular disease, stroke, hip dislocations, unusually prominent scalp veins, loss of the layer of fat beneath the skin (subcutaneous adipose tissue), nail defects, joint stiffness, skeletal defects, and/or other abnormalities are additional distinguishing characteristics. Arteriosclerosis, which occurs in people with HGPS, causes widespread, early-onset thickening of the arterial walls and a loss of their flexibility, which can lead to life-threatening issues in early adulthood or in childhood. At the age of 14.5 years, children with progeria typically pass away from heart disease (atherosclerosis). Children with progeria can develop high blood pressure, strokes, angina (chest pain brought on by inadequate blood supply to the heart), an enlarged heart, and heart failure, all aging-related illnesses, much like anyone else who has heart disease.

An alteration (mutation) in the LMNA gene, which produces the lamin A protein, is the root cause of progeria. The scaffolding that keeps a cell's nucleus together is the lamin A protein. Researchers now think that the nucleus' instability is caused by the lamin A protein's flaws. In progeria, premature aging seems to be caused by cellular instability.
