| | CIGNA - Progeria, Hutchinson Gilford |
 | | Progeria is caused by a mutation of the gene LMNA, or lamin A. The lamin A protein is the scaffolding that holds the nucleus of a cell together. |
 | | Newborns with Hutchinson-Gilford progeria syndrome may have certain suspicious findings may be present at birth, such as unusually taut, shiny, hardened (i.e., "scleroderma-like") skin over the buttocks, upper legs, and lower abdomen; bluish discoloration of the skin and mucous membranes within the midportion of the face (midfacial cyanosis); and/or a "sculptured" nose. |
 | | The researchers determined that the most common cause of progeria is a single-letter “misspelling” in a gene on chromosome 1 that codes for lamin A, a protein that is a key component of the membrane surrounding the cell’s nucleus. |
