Progeria is one of the least known genetic disorders. There are two types of Progeria, the only difference being the age group that it affects. The Hutchinson-Gilford Progeria Syndrome is commonly called Childhood Progeria. The second type of Progeria is Werner’s Syndrome, which is the adult form of Progeria. What basically happens in this disorder is that age is accelerated seven times faster than that of a normal person. For example, for Hutchinson-Gilford Progeria Syndrome, a child could look like he is fifty when he is actually five years old. A twenty year old with Werner’s Syndrome could look similar to a sixty or seventy year old person. There is, even now, not much information known about this genetic disorder because of the scarcity of people with this disorder, not to mention the short life period that they have.
The gene for Hutchinson-Gilford Progeria Syndrome was discovered quite recently on April 16, 2003. Researchers confirmed that the gene, HGPS, is not an inherited disorder because neither parent carries or express the mutation. The mutations to the gene LMNA, which encodes for the Lamin-A protein, causes Progeria. The Lamin-A protein is what provides the framework that holds the nucleus together. Researchers believe that an unstable nucleus caused by a faulty Lamin-A protein brings about Progeria. This gene is located in chromosome 1, but the exact locus has not been announced yet. Researchers say that Progeria is point autosomal point mutation. This misspelling among 25,000 base pairs causes the shortage of the protein made by Lamin-A. This is also a dominant mutation because it is expressed equally in girls and boys. As in other dominant gene mutations, there is a “paternal age effect”, meaning that the mother is, on the average, four or five years younger than the father at the time of conception.
The symptoms of a child with the HGPS gene are very noticeable. Although they appear normal at birth, their age begins to accelerate by they...
