Genetics determine the traits an individual will inherit from their parents. In society today, the role of genetics is crucial; they decide ones physical appearance as well as their personality. However, if there is a mutation located in one of the genes that a child receives it is very likely a deformity will be present. A rare yet fatal defect from a gene mutation such as this is Progeria. This disorder is an unfortunate one that may occur in two forms, either Hutchison-Gilford Progeria or Werner syndrome. Not only do they affect the bone structure and appearance of the child, but they substantially shorten their life spans.
Hutchison-Gilford disorder was first discovered and described by John Hutchison in

People with Progeria are very short in stature and have thin limbs, prominent joints, and hip dislocations (Werner).
Progeria is a rare disorder; therefore, the transmission of the disease from parent to offspring is not a likely occurrence. However, when the disease is transmitted both mother and father must carry a mutant gene. If just one parent is carrying a single mutant gene, they will not show any symptoms of Progeria and will not pass it along to their offspring. When both parents carry the gene, their offspring now has a 25% chance of being born with Progeria..
Progeria is an autosomal recessive disease, which means it is not carried on a sex chromosome. Hutchison-Gilford Progeria is caused by a mutation in Lamin A. Lamin A is a fibrous protein involved in the structure of the nuclear membrane. When there is a mutation in Lamin A it is likely the nucleus loses its normal shape and therefore its function is compromised. As of now, it is known that this is the cause of Progeria itself; however, neither doctors nor scientist can determine what this mutation has to do with the aging-like deformities of Progeria (Kugler).
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
Progeria is a very rare disease and affects about one in 4-8 million children, with an estimated 200-250 cases worldwide. It affects males and females equally and is found in all races. HGPS is not usually passed down in families; it’s extremely rare and almost always happens by
Some ways to detect Progeria are genetic tests of the patient’s blood and clinical exams. Furthermore, the major signs begin developing when the child is around eighteen to twenty-four months old and he will experience accelerated aging even though he was born looking normal. One major symptom is hair loss. Patients are born with hair texture and color, but around six months to two years, the hair begins to fall out. Then, from two to three years, they are usually bald, but might have some thin, light hair. Loss of eyelashes and eyebrows are also experienced. Along with hair loss, these children grow slowly resulting in a shrunken physique and minimal weight gain. For males, their approximate height and weight are 40 inches and 25 pounds; but females are about 32 inches and 20 pounds. In When Good Things Happen to Bad People, doctors have stated these kids will "grow to be very short," and "would never grow much beyond three feet."( Kusher 1-2) Moreover, there are distinctive physical traits in the face and body. "By the second year of life, there is also under development (hypoplasia) of the facial bones and the lower jaw." ("Hutchinson-Gilford Progeria") Also, "the face appears disproportionately small in comparison to the head, and bones of the front and the sides of the skull (cranium) are unusually prominent." ("Hutchinson-Gilford Progeria") Some other characteristics observed in the face are a thin
In the beginning of the second year, and last half of the first year the children will stop growing and gaining weight which is accompanied by the hair loss. Between the ages of two and three year the classic facial feature of the Progeria begin to show (Hennekam, 2006 pp. 2603-2624).
It is an inherited genetic disease. It is passed down in families in an autosomal recessive pattern, which means both copies of the gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show any symptoms. Around 1 person in every 150 people are thought to be carriers. There are two types of Krabbe disease the infantile and the late on-set. The infantile form, which affects 85 to 90% of people with
Experts do not believe that Progera is hereditary. They say it is due to a rare gene change, which happens purely by chance. A non-twin sibling runs the same risk of having Progera as any other child from another family. In about 1 in every 100 cases of HGPS the syndrome is passed down to the next generation within the same family. The health care professional will possibly suspect Progeria if the signs and
Hutchinson-Gilford Progeria Syndrome is a condition in a child that has rapid growth at an early stage of childhood. The accelerating age starts in early infancy, where the child will grow slower than other children, but normal when first born. Usually the "failure to thrive" happens in the first year after being born. This condition does not stop the development of motor skills, like sitting, standing, and walking. The child will also have a normal immune system that helps with healing normally after being sick or getting scrapes/ cuts. This condition over time is life threatening to children who have been diagnosed with the progeria syndrome. Severe hardening of arteries occurs in the younger years of children, causing them to have heart attacks and strokes. Deaths have been between ages six and twenty years, the life span is usually 14.6 years after being diagnosed with the syndrome.
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

Jonathan Hutchinson in 1886, and eleven years later by Dr. Hastings Gilford, using the two names the disease got its first name Hutchinson Gilford syndrome. Both doctors stating the scene of pre-matured kids. Currently humans are the most discussed primary organism to be affected by Progeria. As said in the beginning, Progeria is extremely rare, so rare that approximately only one in four to eight million newborns get it. With those odds said, it approximated that only 200-250 kids worldwide have this condition. Now parents usually don’t pass down progeria to their children, and both boys and girls have equal chances of getting this disease. In the race to help ease/cure the effects of progeria, there was an European clinical trials, created mice to model the effects of progeria, they did this by injecting the genetic mutation G608G, which is the genetic mutation responsible for progeria in humans with progeria. After 3 weeks were over many of the mice had started to show the symptoms of progeria, such as weight loss, growth defects, and cardiovascular and metabolic anomalies. These mice were later on, used to find a “mutation-targeted treatment”. With the new treatment developed, the Europeans were able to increase the mice’s lifespan from 155 days to 190 days, adding a stunning 35 days more to the mice’s lives. One of the major impacts that this disease, was made by a 17 year old boy named Sam Burns, he became increasingly popular
Hutchinson- Gilford Progeria Syndrome is reported about 1 in 8 million newborns (Parker 16). Hutchinson-Gilford Progeria Syndrome equally affects both sexes and races of children and gives them an appearance of rapid aging (Nordqvist 1). The symptoms of this disease show around eighteen to twenty-four months of
Hutchinson-Gilford progeria syndrome is a genetic disease which consist of the rapid beginning of aging when you are an infant. This rare affection only affect 1 of 7 millions of newborns. It doesn't have a gender in particular, however, the majority of children with this condition are light skin (97% of patiences). Progeria damage different tissues like bones, muscles, skin, subcutaneous tissue and vessels. This disease do not have a cure so the kids with progeria their average life is between 8-21 years old.

What is Progeria? Well to put it into simple terms, Progeria is a genetic mutation that causes weakened skeleton and muscles (Ho, C. Y., Jaalouk, D. E., Vartiainen, M. K., & Lammerding, J. (2013 )as well as a perceived increase in age rate which often leads to people affected with Progeria to die during their teens or even earlier. Pargein only affects 1 in every 48 million (Bhattacharya, S. (2011) children born. And in 1998 only around 80 people had it.
It was found in recents studies that KS is most commonly inherited maternally. Due to the regular levels of aneuploid sperm men produce, all men in the general public have a risk of producing an aneuploid child, therefore producing a child with KS. Knowing this, a man does not necessarily have to have KS to still produce a child with Klinefelter syndrome however it is more common for a child to inherit Klinefelter syndrome if his father also has KS.
