Achondroplasia Research Paper

5. What is the prevalence and prognosis of this condition? Is it an inheritable (genetic) condition/disease? (1 point)

Achondroplasia is when cartilage during development is not developed into bone, which results in dwarfism. This condition also characterized by short limbs is initiated by a gain of function mutation in the FGFR3 gene. This mutation is a point mutation. When this mutation occurs, the receptor of the FGF does not need the FGF signal to be activated. This causes the chondrocytes to stop dividing and start differentiating into cartilage prematurely and the bones fail to grow to their proper length, thus resulting in the short limbs that result from this mutation. (textbook) The FGFR3 gene encodes for the Fibroblast growth factor receptor 3 protein. Textbook

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.

Achondroplasia is a genetic disorder in which there is a growth hormone deficiency, or there is a genetic mutation in either the father’s sperm or mother’s egg. (mayo clinic, March 20,2014.) Achondroplasia was the first discovered in ancient Egyptian records. People with achondroplasia were considered people with supernatural powers. Many people call dwarfs midgets but to them, it is very disrespectful because midget literally means little person. Some acceptable names that you can use that will not offend them would be little people, LP, person with short stature, or dwarf. Even though dwarfs feel as if they do not have disabilities, the Americans with Disabilities Act (ADA) will protect the rights of dwarfs. (who discovered it? March

Achondroplasia (ACH) is the most common form of short-limb dwarfism occuring in 1 in 15,000 to 28,000 births and appears to be slightly more prevalent in females, but indiscriminent toward race (1-3). Evidence has been found in Egypt for cases of ACH dating back as far as 4500 B.C. (4). In simplest terms, ACH is a disease where the dwarfing of bones formed in the cartilage occurs (5). There are many features that accompany this disease including rhizomelic (proximal) shortening of the extremities, megalencephaly (enlarged brain), short stature, trident hand, and frontal bossing (prominent forehead) (1, 3, 4, 6-8). Expression of this gene at high levels is primarily found in cells of the nervous system and the cartilage rudiments and

Here are some interesting facts on Achondroplasia. Achondroplasia is a small limbed dwarfism. A disorder of bone growth which stops the changing of cartilage to bone. Here are some major causes of mutations in the FGFR3 gene. The symptoms of Achondroplasia are health problems such as breathing stops or slows sown at small amounts of time, obesity, ear infections, in childhood individuals get a permanent sway of lower back, and pain and weakness in legs. Those are some interesting facts on Achondroplasia.

Surgery. This is rarely needed, but it may be considered in adults who are done growing and continue to have symptoms.

There are treatments to make living with this disorder a little easier. Babies born with this need immediate and intensive care in the NICU. Babies born with this are less able to maintain a safe body temperature. They are more prone to fluid loss, dehydration, and life threatening infections. In their first week of life to have any chance of survival they may need: intravenous tubes to deliver fluids and nutrients. They also need monitoring of electrolytes and sodium, lubrication for their eyes if they’re forced open. With having this disorder they have a hard time keeping their body temperatures normal, which means they need help in doing so… They need to be in a high humidity incubator to even maintain a normal body temperature and prevent cracks in their skin. The Doctors can prescribe antibiotics so the infection does not spread any further. Doctor can also prescribe retinoids which is any type of cream to accelerate the shedding of the skins scales. It is an ongoing treatment of keeping the skin moisturized and avoid more scaling or cracking that could lead to more infection. How long do babies diagnosed with this disorder

Apparently, three is no cure spina bifida, because of the nerve, tissue that is damages or lost cannot be repaired or replaced, and without the cure, the treatment for this disorder may include surgery, medication, and physiotherapy. Treatment is also defending on the type and severity of the disorder. "Types of spina bifida are; spina bifida myelomeningocele, the most serious form of the birth defect and not only membrane protrude from the vertebral cleft but the spinal cord also pushes through the hole. spina bifida meningocele is the rarest form of this neural defect, it characterized by a protrusion of the protective coating around the spinal cord through the cleft or the hole in the vertebrae, surgeon can repair and remove this cyst although there may still have some damage to the spinal

What are the most common treatments for the condition? How long have these treatments been in use? Are they newer advances or older

The symptons include facial disformities including downward slanting eyes, smaller lower jaw (also referred to as micrognathia),underdevloped zygoma, drooping

have been trying to find the exact cause of this disease and how it can be treated so

At birth, children with familial dysautonomia are diagnosed by a distinct set of symptoms. (FD Facts) Poor muscle tone and lack of tears are two symptoms that can be detected very early. As they get older they have a hard time maintaining body temperature, they hold their breath for long periods of time and have a delay in speech and walking. The cause of these symptoms is due to a defect IKBKAP gene.

WHS is a genetic condition, some of the major features of this condition are characteristic facial appearance. People who have this disease also have delayed growth and development, intellectual disabilities and seizures. The major causes of WHS is a deletion of a region in chromosome 4 called 4p16. Some of the symptoms are Ataxia, which is the loss of full coordination. There are facial characteristics such as Greek warrior helmet appearance of the nose, widely spaced eyes, and Micrognathia, which is when the jaw is small and makes it hard to eat and breath.

The diagnosis of the disease, its cause or causes, stage, treatment and prognosis will be sought from the pediatrician. He establishes and explains the connection between the disease and the patient's family history. He prescribes appropriate medicines and medications to alleviate the patient's symptoms. The moral principles surrounding the couple's decision concerning the disease are contributed by the ethicist. He warns against the double-effect situation in this disease condition. He emphasizes that birth defects
