Literature Review Paper On Progeria

Hutchinson-Gilford Progeria syndrome, also known as HGPS, or Progeria, is a very rare genetic disease caused by a mutation in the cell. In 1886, Jonathan Hutchinson first reported case of a 3 ½ year old boy who had the appearance of an old man. In 1897 Hastings Gilford reported a second case with similar features. However, this mystery disease didn’t have a name until 1904, when it was named after the two men. People who have HGPS usually star showing symptoms by the age of 2, and only live to be a teen-mid-20s.

This syndrome is not very common, because it is a rare condition. Its prevalence is not certain, but the proximate amount is 5 to 10 individuals per million newborns. Research workers appraise that there are approximately 200 to 300 individuals around the world who have this disorder. It is observed with equivalent recurrence in both males and females over all ethnic groups.

This syndrome is from a mutation of a gene on chromosome 15 and this causes problems in the production of fibrillin-1 which is a protein that is an important part of connective tissue. The name for the gene is FBN1. Basically, it is the “glue” that helps to support the tissues in the human body. A child born to a parent with this syndrome has a 50% of having it. However, in the remaining 25%, neither parent has the disease which gives them a 1 in 10,000 chance of having a child with this disorder. When a child of two unaffected parents is born with it then the genetic mutation occurs in either the egg or sperm cell at the time of conception.

The purpose of this paper is to discuss the effects of the disorder and how genetics and biochemistry work together to create this

The disease may be found on a chromosome analysis. There is no said or found cure or treatment for the disease. It’s very rare, but not impossible, to get the disease from parents or grandparents.

In conclusion, progeria is a deadly genetic disease characterised by premature aging. Caused by a chance occurrence in the egg or sperm, families have no warning until symptoms manifest around the age of two. Though there is treatment for the disease, there is no cure. Donating your time or money to help progeria patients is a worthy cause. Hopefully, in the future a cure will be found and progeria will not affect children around the

Because the genetic change is not an inherited disorder but rather due to random error during development, there is no specific race, gender, or regions in the world that are affected more than the other (Cassidy, 2012). The most common abnormality associated with PWS is due to the deletion of the paternal chromosome 15, which is found in approximately 70% of cases. Another possibility is due to maternal uniparental disomy which occurs in about 25% of cases. This is when the child does not inherit the paternal copy of chromosome 15, but instead receives two copies from the mother. The last 5% of cases is another form of genetic imprinting where the father’s chromosome 15 is present, but are not functional known as microdeletion (Griggs, 2015). Although research has narrowed down the region of the affected chromosome, the specific genes that are involved have yet to be found. There are also no solid indicators as to how they play into the development of PWS symptoms (Khor, 2016).

They are involved because the LMNA gene produces several slightly different proteins called laminas, of the major ones being Lamin A (also known as progerin) and Lamin C. These proteins are generally made throughout the whole body’s cells. The disease is causes the LMNA gene which to become mutated. Althought, this does not causes any harm to lamin c protein, it causes the lamin A protein to misshape, by missing out on 50 amino acids near one end. This is bad because the lamin A protein is a component the nuclear cell membrane. This misshaped version of lamin A is which is responsible for the disorder; it makes it so that it cannot be processed properly in a cell, which then causes a disrupted shape in the nuclear envelope. All in this mutation damages a cell’s structure and function to a nucleus which in turn causes the cells to die

Progeria is a rare, fatal, genetic condition that comes from the Greek word progeros meaning prematurely old. In the greek language, the word ‘pro’ means before and the word ‘geras’ means old age. Another name for progeria is Hutchinson-Gilford Progeria Syndrome. Hutchinson-Gilford Progeria Syndrome (HGPS) was first described in 1886 by Dr. Jonathan Hutchinson and also in 1897 by Dr. Hastings Gilford in 1897 – both in England.

Progeria, otherwise known as Hutchinson-Gilford syndrome is an extremely rare, genetic childhood disorder with a reported incidence of about one in a million. Hutchinson reported the syndrome in 1886 when he found the first patient with Progeria. In 1904 Gilford described a second case of Progeria, thus creating the term to reflect the syndrome’s senile features. There are only about a hundred reported cases since the disorder has been discovered over a century ago. Currently, there are about thirty to forty known cases worldwide of Progeria. Affected children age up to seven times faster, have “plucked bird” appearance, many health problems and their lifespan is about thirteen years. There is neither known cause nor cure for this

Affecting 1 in every 4-8 million people worldwide, Hutchinson-Gilford Progeria syndrome is a rare and fatal genetic condition characterized by the appearance of rapid aging in children. It affects both sexes and all races equally. It is caused by a mutation in the gene called LMNA, which produces the lamin A protein, a structural scaffold that holds the nucleus of a cell together. The abnormal form of the lamin A is called progerin, and it causes the nucleus to be unstable. Progeria is an autosomal dominant disorder; however, in almost all cases it occurs as a spontaneous mutation. It is a point mutation, meaning it’s just a one letter typo.

A boy was born with this syndrome and had to be put on dialysis one year after being born for 10 hours every day for two years.

The Progeria Research Foundation was founded by Dr. Leslie gordon and Dr. Scott Berns who found out their son Sam Berns was diagnosed with Progeria just shy of his second birthday. It was then when these two doctors who never heard of the disease either, were informed and started doing research on behalf of their son, Sam. They quickly found out that the condition was so rare there was no where for the victims to go, no medical help, no place for parents of the children to console and no source of funding for researchers who were trying to research Progeria. This lack of information that had desperately became reality for this doctoral family became the fuel behind their inspiration to change the lack of funding, support and awareness.

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
