FGFR3 is a gene that encodes a protein involved in bone growth. A mutation in FGFR3 causes the genetic disorder achondroplasia, which results in dwarfism. The mutation causes premature activation of the STAT signaling pathway, leading to decreased bone growth. One paper described the initial discovery of FGFR3 through identifying similarities to other FGFR genes and cloning the gene. A second paper discussed how the FGFR3 mutation specifically causes achondroplasia by prematurely activating the STAT pathway and decreasing chondrocyte proliferation.
Birth defects are abnormalities present at birth that can cause disabilities or death. They range from minor to serious and affect about 150,000 babies born in the US each year. Common birth defects include spina bifida, caused by inadequate folic acid during early pregnancy and clubfoot. Spina bifida occurs when the bones of the spinal column do not fully close, leaving an opening. Early prenatal surgery may help repair some birth defects. Fetal alcohol syndrome, caused by drinking during pregnancy, can result in physical deformities and neurological issues. Cerebral palsy is caused by brain injury before or during birth and results in difficulties with movement and posture. Down syndrome, caused by an extra 21st chromosome, leads to intellectual

Congenital talipes equinovarus, or clubfoot, is a common birth defect where the foot is twisted out of shape. It occurs in about 1 in 1000 births and is more common in males. Genetic factors are believed to play a role. Treatment usually begins within the first weeks of life and involves casting and stretching to realign the foot, sometimes with minor surgery. Properly fitted braces are then worn long term to maintain the corrected position and allow normal walking. With early treatment, most children with clubfoot can walk normally.
This document discusses congenital talipes equinovarus, or clubfoot, which is a common birth defect where the foot is twisted out of shape. It occurs in about 1 in 1000 births. Clubfoot is usually an isolated problem in otherwise healthy newborns and is twice as common in males. Treatment typically begins within the first weeks of life and involves casting and stretching to realign the foot, sometimes with minor surgery. Proper use of braces after treatment is needed to prevent the foot from returning to its original position. The cause is usually unknown but genetics and environmental factors may play a role. Nursing care focuses on supporting parents, educating on treatment and self-care, and protecting the skin during casting.
Club foot, also known as congenital talipes equinovarus, is a congenital deformity where the foot is twisted out of shape. It occurs in approximately 1 in 1,000 live births. While the exact cause is unknown, risk factors include family history, smoking during pregnancy, and lack of amniotic fluid. Treatment options for club foot include stretching and casting, which is the most common approach, as well as stretching and taping or surgery. With early treatment, those with club foot can often walk normally and lead active lives.

This document provides information on congenital talipes equinovarus, or clubfoot, which is a common birth defect where the foot is twisted out of shape. It affects about 1 in 1000 births. Clubfoot is caused by shortened tendons in the foot and can be either idiopathic (no known cause) or associated with genetic factors or other conditions. Treatment typically begins within the first few weeks of life and involves casting and stretching to realign the foot, sometimes with minor surgery. Proper bracing after treatment is needed to prevent recurrence. The document outlines nursing assessments and care goals for managing clubfoot.
Progeria is an extremely rare genetic condition where children age rapidly, experiencing many signs of aging at a very early age. It affects about 1 in 4-8 million births. The main symptoms include baldness, wrinkled skin, joint stiffness, loss of body fat and muscle, and cardiovascular problems. Average life expectancy is 13 years. While there is no cure, treatments can help manage symptoms and slow progression, such as low-dose aspirin, physical therapy, and lifestyle modifications. Progeria is caused by a genetic mutation and provides insight into normal human aging processes.

Skeletal dysplasias are a heterogeneous group of genetic disorders that result in abnormalities of bone or cartilage growth and structure. They occur due to mutations that affect endochondral ossification. Achondroplasia is the most common type of skeletal dysplasia and dwarfism, caused by mutations in the FGFR3 gene. It is characterized by disproportionate short stature with short arms and legs, frontal bossing of the head, midface hypoplasia, spinal stenosis and risks of neurological complications. Diagnosis is based on clinical and radiological findings including characteristic changes to the long bones, skull and vertebrae.
This document provides information about arthrogryposis, including:
1) It defines arthrogryposis as non-progressive joint contractures present at birth involving at least two body areas.
2) Pathological findings include absent or small muscles replaced by fibrofatty tissue, thin bones, and small nerves.
3) Causes may be genetic, environmental, or unknown. Treatment involves rehabilitation, serial casting/splinting, and surgery to correct deformities and improve function.
Osteogenesis imperfecta (OI), or brittle bone disease, is a genetic disorder characterized by bone fragility and fractures. There are 8 types that vary in severity. Type I is the mildest and most common, while Type II is the most severe and often fatal. OI results from mutations in collagen genes and affects the bones, skin, teeth, and lungs. Symptoms include fractures, skeletal deformities, short stature, and blue sclerae. Treatment involves bisphosphonates, surgery, bracing, and physical therapy. Individuals with OI require modifications to activities of daily living like bathing, dressing, eating, and mobility due to their fragile bones and risk of fractures. They also

The Human Life Cycle
Birth to Old Age –
What is the human life cycle?
How does nutrition influence our life cycle?
How have our cultural changes in diet and nutrition influenced our development?
So far we have looked at ways in which human beings vary in their phenotypes. Another way that humans have evolved is in our life cycle. All organisms have a cycle of life and eventually die. In this lecture, we are going to consider how the developmental and maturation cycle for homo sapiens has changed over the course of our evolution. When we were in our human evolution section of this course, we watched as maturation rates slowed as species evolved towards Homo sapiens. We have the longest maturation period of any primate, but when we enter this period and get out of it has been altered.
1
Humans are a generalized species
Homo sapiens are very generalized and flexible, we also call this plastic.
We live, eat, and respond to a number of different environments and circumstances.
As environments have changed, our culture has evolved to make us more adaptive.
Drastic cultural changes over the last several decades will have profound impact on our biology.
For this lecture, think back a bit to how flexible and adaptive we are. We have the ability to adapt to many environments and we have. On top of that, we have altered our cultures quite a bit and this has impacted our evolution.
2
Does our original body and life cycle match our ancestors 300kya ago?
We are a species that evolved in subtropical Africa some time around 300,000 years ago.
Rapid agricultural and cultural changes have caused major divisions between generations; think how different your life is from your grandparents.
We have to consider both biological and cultural influence on how the cycle of life has changed.
Something we have to consider is that humans haven’t been around very long as a species. Since it takes us so long to reproduce, we haven’t been on the planet long enough for us to really have evolved in any major ways. What this means is that technically, most of us are still evolved to live in sub-tropical Africa, in small, kin-based families, who hunt and gather. Yet we live in a rapidly modernizing world. Is this rapid change affecting the way we develop and at the rate we do? Let’s consider some examples by looking at the normal life cycle.

Most women do not necessarily know that they are pregnant as early as 2 weeks after conception. However, the neural tube and thus the nervous system is already forming. This means that nutrition is an absolutely integral part of daily life. If malnutrition or other nutrition issues affect the child this young, then the nervous system is already being harmed.

Achondroplasia is a type of dwarfism caused by a mutation in the FGFR3 gene, which regulates bone growth. It results in short limbs, an enlarged head, and limited joint movement. While it cannot be cured, treatment focuses on monitoring health, preventing complications, and alleviating symptoms like back pain and sleep apnea. People with achondroplasia can live normal lives through adaptations and with support from family and community.
During the preschool years from ages 2 to 6, children experience significant physical, motor, and cognitive development. Physically, children nearly double in height and weight during this time. Their bodies also become less round and more slender as bones strengthen and muscle increases. Motor skills like fine motor coordination are practiced and improved. Cognitively, the brain grows rapidly through myelination and connections between hemispheres, supporting advances in memory, attention, and motor skills. By age 5, the brain weighs 90% of an adult's. Most children show preference for right or left handedness by the end of the preschool years.

Pituitary Dwarfism Research Paper
1. Pituitary Dwarfism Research Paper
Pituitary Dwarfism is a disease where the growth of someone is slowed or delayed, usually due to a
malfunction in the pituitary gland and it results in a less than normal stature. It takes place in the
pituitary gland which regulates the production of hormones and it causes normal stature with short
limbs. Since the height and growth is decreased, it results in what many people refer to as a
"midget." The Pituitary gland produces many hormones such as the growth hormone, luteinizing,
thyroid, prolactin, follicle–stimulating, and oxytocin. A decrease in the production of hormones in
the anterior pituitary is what causes most forms of dwarfism. The decrease occurs during childhood,
and it causes the body to be developed proportionately, but at

1800's and 1900's prior to the Industrial revolution. The Amish do not partake in the uses of modern
technology. For instance, their means of transportation are horses and walking. Our current means
of transportation are cars, motorcycles, buses, trains, etc. Another instance is that the Amish still
practice agricultural farming with little no involvement of machinery. They also refuse to use
chemicals refuse to use chemicals such as pesticides as we do to repel bugs from our crops. The
Amish feel that our two different worlds should be isolated and distant from one another to keep
their traditional way of life away from the modern world. The secluded community known as the
Amish avoid contact with the outside word of their community. This leads to having their
community limited in the means of communication to only each other. By limiting their means of
contact with others, the Amish limit themselves to only one social circle. This also limits them in
possibly picking their spouse to only be from the Amish within their own community. Scientifically

3. Spondyloepiphyseal Dysplasia Essay
Spondyloepiphyseal dysplasia is a type of dwarfism. Dwarfism is a disorder can happen because of
several different reasons. This type of dwarfism occurs because of a defective gene from at least one
parent that is passed down to its offspring, but could also occur because of a new mutation in the
gene passed down. Although there are different types of dwarfism they all cause the person to be
short, and sometimes disfigured or distorted. This type and most of the others not only affect the
persons legs, but can also effect different parts of their body. There are treatments to help with these
other problems that go with dwarfism, but you can not fully get rid of it. Spondyloepiphyseal
dysplasia mostly occurs in a child when one of their parents passes down a defective gene to them.
Around 80 percent of these people have average–size parents though, this can be caused by new
mutations that have developed in the parent or parents gene that gets passed down to their offspring.

4. Achondroplasia Research Paper
Abstract:
Dwarfism is a syndrome where a person has abnormal bone development. Symptoms include short
stature, bowed legs, curvature of the lower spine, and a prominent forehead. The most common type
of dwarfism, Achondroplasia, is characterized by a glycine to arginine mutation on codon 380 in the
fibroblast growth factor receptor transmembrane domain 3 gene. When the mutated fibroblast
growth factor receptor 3 protein interacts with a fibroblast growth factor ligand, the receptor is
stabilized and a cascade of events occur. Downstream receptor pathways that are affected by the
mutation involve signal transducer and activator of transcription 1 and phospholipase C, gamma 1.

Achondroplasia is a disease that is dwarfism which is a change in growth of long bones, in resulting
very short limbs. Sometimes a face that is small in relation to a normal face sized to skull

condition. The major disorders in this disease is during early fetal development, much of your
skeleton is made up of cartilage doesn't convert to bone. Caused by mutations in the gene, FGFR3.
This gene instructs your body to make protein necessary for the bone growth. It interferes with the
normal skeleton development. The symptoms of this disorder is when at birth/child: short legs and
arms, an underdeveloped area of the face between the forehead and upper jaw, short fingers, ring
and middle finger point away from each other, and a disproportionately large head compared to the
body. The symptoms for health: decrease muscle tone which can cause delays in walking and other
motor skills, apnea which involves brief periods of slowed breathing or breathing that stops,
hydrocephalus or water on the brain, spinal stenosis which is a narrowing of the spinal canal that

For example, if the child uses their forearms in a pronated position to carry items, stretching the
muscles may reduce the ability to functionally performing tasks. The biomechanical theory is the
typical frame of reference used in the treatment sessions. Biomechanical treatment of stretching,
positioning, and proper joint alignment can be beneficial for increased joint ROM. The areas of
occupational performance that are affected due to limited ROM and hand grasp would include
ADL's of dressing, grooming, feeding, toileting, playing, education, and social roles. The
performance components that might be affected are restricted ROM, bones and joints that are bent
or curved in atypical position. The child's fingers and thumb may not have active movement, joint
stiffness, muscle weakness, and trouble ambulating if the child has club feet. Psychosocially the
child may have self–confidence issues and dependency behaviors" (Reed, 2011). "The focus for
evaluation and treatment could involve use of tests to see what the current functional ability is, in
the occupational areas of their life. One test that is used to evaluate the physical functioning of the

Competition is when organisms compete for resources. Not all organisms are created equal. This
differences in the organism 's fitness is called differential in fitness. How does this apply to humans?
Humans are mutating right now. Some are caused by genes, while some are caused by the
environment. Dwarfism is usually caused by genes, and will make the person small in stature.
Osteoporosis is usually caused by the environment, and will the person 's bones weak and brittle.
Dwarfism is usually caused by genes. Achondroplasia is a skeletal condition which causes
dwarfism. Some adult heights were recorded as short as 64 cm. Some Dwarfs can be proportionate
or disproportionate. This is usually because of the inhibition of the development of bones. Dwarfism
is caused by the FGFR3 gene. A person with achondroplasia and with two average–size parents
received one mutated copy of the gene and one normal copy of the gene. A person with
achondroplasia may pass along either a mutated or normal gene to their own children. There is no
real, all around treatment, due to the skeletal disorders, but in certain cases of pituitary dwarfism, it
can be treated by giving human growth hormone. Since the bones grow if different ways, sometimes
surgeries that can correct some of the displacement of the bones are needed. This is usually done
with limbs and mainly the spinal cord. Osteoporosis causes bones to become weak and brittle,

While some procedures can correct certain problems, others to fully correct stature are unheard of.
Surgical procedures such as extended limb lengthening, and stabilization of the spine, can help
increase height and posture, but come with as many risks as any other surgery ("Dwarfism:
Treatment"). Other patients have the option of undergoing hormone therapy. This form of therapy
injects a synthetic hormone that can extend the growth of the limbs, to try and achieve the average
adult size. Treatment can last from adolescent years all the way into adulthood to ensure the
complete growth of muscle, fat, and bones ("Dwarfism: Treatment"). In addition to limb treatment,
there is a way to treat hydrocephalus in patients by placing a shunt to remove excess fluid
surrounding the brain ("Dwarfism: Treatment"). Thus opening a wide range of options to relieve
stress and other deformities that are associated with achondroplasia.
When trying to understand achondroplasia, looking at the cause of the mutation as well as the
abnormal malformations, while being educated on the possible treatments, will help to gain
knowledge on the severity of the genetic deformation. Even with the wondrous medical procedures
today, there is still a vast amount of opportunity for better development to help treat achondroplasia.

Edgar Allan Poe: the name alone conjures an atmosphere of darkness and mystery. With notoriety
like that, it is awful peculiar that so little is definitely known about the man: particularly with his
personal on–goings, relativity or interaction with his world, and of course, his outré death. Based on
the intertextual references he placed throughout several of his works, researchers and readers alike
are open to interpretation and speculation of the great, and awe–inspiring Poe. For instance, his
short story "Hop–Frog" sparks readers' interest with a series of intertextual references/allusions
regarding disability, such as his subtle nuanced phraseology, and carefulness in characterizing
otherness amongst the members of the society detailed. Character interactions paired with Poe's
distinct phraseology are the intertextual references that allow for an interpretation of disability: what
the societal perception was of disability, both physical and mental, how the disabled were
received/treated socially, and why the plight of the physically ill–equipped became an underlying
theme within Poe's works. The short story "Hop–Frog," possesses these intertextual references in
order to build the case that Poe himself was somewhat inebriated by disability, both through
experience and internal struggle. It is important to first establish the criteria for disability of this
time. The American Psychological Association is "the largest scientific and professional

submit to some prenatal screening. Usually this involves a blood sample of the mother's blood in
order to determine whether she is likely to have a child with spina bifida, neural–tube defects, or
Down syndrome (Golden). United States genetic centers now offer DNA tests for over 30 or 40 of
the more commonly inherited disorders. Those including cystic fibrosis, susceptibility to breast
cancer, X syndrome, Huntington's disease, Duchenne muscular dystrophy, and many other various
disorders (Golden). Also, with recent developments, couples are able to have a pre–implantation
genetic diagnosis (PGD). This procedure allows the testing of genetic disorders before germination.
It consists of "petri–dish" testing of sperm and egg cells donated by the soon to be parents. This
procedure prevents the idea of abortion, for if genetic problems occur, you are not destroying a
fetus, but simple flushing away embryo cells. Another article that I have recently acquired has more
to do with the ethical standpoint of genetic tailoring, than the scientific. In recent years, a rather
large sum of attention has been placed on whether or not the possibility of genetic testing will harm
our communities (Gooding).

Stereotypes: Has the Role of Peter Dinklage Progressed?
In 1952 theorist Frantz Fanon wrote The Fact of Blackness, an article that illustrations the struggles
of being an African– American in then modern–day America. Fanon suggested African Americans
live with a prescribed stereotype of "blackness". Because of the color of their skin, African–
Americans have an image created for them. Due to this prescription, many individuals are unable to
create their own persona. Fanon states that a black person is the slave of his or her own image.

The most common type, called Achondroplasia is the cause of about 70 percent of all dwarfism. It
makes your arms and legs shorter than that of your torso. Achondroplasia affects about 1 in 15,000
to 1 in 40,000 live births.
To understand Fanon one must look back to the beginning of the cinema. Stereotypes were prevalent
in movies since the beginning of the cinema. One of the first movies to show a stereotypes was the
1915 silent film Birth of a Nation. In the D.W. Griffith film the African American plays the
stereotypical slave of the south after the civil war.

Barker shares a statement about her voice about black stereotypes:
"Since the early twentieth century, critics, filmmakers, and actors such as W.E.B. Du Bois, Clarence

History
Achondroplasia is the most common diagnosis and most frequent form of those who are considered
to be dwarfs ("Learning About", 2016). When one thinks of dwarfism, they think of a short stature
with short arms, legs, and a large head. It occurs in one in every 15,000 to one in 40,000 live births
("Learning About", 2016). According to BBC News (2005), researchers found that the earliest
biological evidence of dwarfs dates back to a Predynastic Period called the "Badarian Period" (4500
BC) in addition to several skeletons from the Old Kingdom (2700 – 2190 BC). There has been
evidence of dwarfism in ancient Egyptian times. Dwarfs were held in high regard in ancient Egypt
even having two dwarf gods that they worshiped named Ptah and Bes ... Show more content on

Obesity can be a common factor in achondroplasia and steps to avoid it is recommended to start in
early childhood (Learning About, 2016). If difficulty breathing or sleep apnea has been observed,
there are surgical options to help correct these issues. There are also medical tests to evaluate signs
of spinal cord compression and hypotonia that are recommended (Learning About, 2016). If a
reduced foramen magnum size is observed in medical tests, there may be a need for suboccipital
compression to reduce pressure on the spinal cord (Achondroplasia, n.d.). Middle ear infections are
quite common in accompanying this disease and must be managed accordingly (Achondroplasia,
n.d.). Other management strategies may be less thought about, however, those growing and living
with this disease face many hardships that those of normal stature do not. This poses psychological
turmoil that can be prevented by talking with therapists available to help guide those through this

15. Disproportionate Dwarfism
Dwarfism is short stature that results from a genetic or medical condition. Dwarfism is generally
defined as an adult height of 4 feet 10 inches (147 centimeters) or less. The average adult height
among people with dwarfism is 4 feet (122 cm). Many different medical conditions cause dwarfism.
In general, the disorders are divided into two broad categories: Disproportionate dwarfism. If body
size is disproportionate, some parts of the body are small, and others are of average size or above–
average size. Disorders causing disproportionate dwarfism inhibit the development of bones.

So the head, trunk and limbs are all small, but they're proportionate to each other. Because these
disorders affect overall growth, many of them result in poor development of one or more body
systems. Growth hormone deficiency is a relatively common cause of proportionate dwarfism. It
occurs when the pituitary gland fails to produce an adequate supply of growth hormone, which is
essential for normal childhood growth. Signs include: Height below the third percentile on standard
pediatric growth charts Growth rate slower than expected for age Delayed or no sexual development

17. Essay On Achondroplastic Dysplasia
Achondroplasia is a disorder most commonly associated with its expression of dwarfism in those
affected by it. Also referred to as Achondroplastic Dwarfism and sometimes abbreviated ACH, a
common definition follows that it is a genetic disorder disturbing the normal growth of cartilage.
This disorder, which affects all populations and is indifferent to gender, occurs when there is a
mutation in one specific gene; the FGFR3 gene, on chromosome four. This mutation typically
occurs as a de–novo gene alteration, but is inherited as an autosomal dominant trait if passed on
from a parent/parents. Although a seemingly small difference, the genetic mutation associated with
Achondroplasia causes drastic differences in body appearance when compared to people without
this disorder, mainly concerning the "abnormally short stature" it is characterized by (1).
Additionally, individuals affected by this mutation face a lifetime of physical and social challenges,
as well as the possibility of dangerous medical conditions.
While the condition of extremely short stature is commonly called dwarfism, the term "skeletal
dysplasia" refers to over two hundred disorders associated with much shorter than average height

If the disorder is inherited from biological parents, it does so as an autosomal dominant trait,

percent of the roughly two hundred and fifty thousand people around the world living with

approximately 81 cases reported so far with odds of 1/1,000,000. A few cases have been severe to
the point of endangering the mother's life. This type of dwarfism affects the human skeleton in such

Metatropic dysplasia is inherited and can be passed down, meaning that is its autosomal dominant.
It is also possible that there will be reoccurrences between siblings, though it is variable over time.
Testing of the TRPV4 gene is available through CTGT and other corporations that specialize in
genetic sequencing. Prenatal ultrasound scans will show narrow spinal canals and shortening of long
bones and the supporting structure. Treatment of metatropic dysplasia after birth is possible but its
effectiveness varies from each case and it is often an aggressive and labor intensive path to follow.
Doctors' main goals for patients with MTD are to establish satisfactory respiratory and pulmonary
functions as well as reducing the amount of skeletal deformity. This may require several surgeries
that have their own risks and outpatient treatment plan. If doctors can keep patients with MTD alive
for longer periods of time, they will be able to determine which methods of treatment are the most

How growth hormone regulate various body functions in adults. The growth hormones mainly
regulate the body functions via feedback loops. The process is a two way mode of communication
whereby the target organ releases molecules that regulate the endocrine. The feedback loops are

disorder can be classified based on the underproduction or excess production of the hormone
(Medical Discoveries, 2011). The growth hormone is mainly produced from the brain and it
stimulates insulin–like factor (IGF–1). It also mediates the actions of HGH which regulates variety
of biological activities including cellular division, development of the body, overall growth and

The film "The Tin Drum" is a German movie made in 1959 based off of the novel written by Gunter

According to the case Dwarfism: When Is a Fetus Normal? Achondroplasia is a bone growth
disorder that causes disproportionate dwarfism in which cartilage is not properly converted into

stature in the legs and arms, with a normal sized torso and the head is enlarged. Charles and Amanda
Harrelson requested a genetic test and elective abortion. Amanda is pregnant for the first time and is
three months into an apparently normal pregnancy. However, she and her husband were both
achondroplastic dwarfs and had requested tests for their fetus developing evidence of
achondroplasia.
This results from a mutation in a single gene called fibroblast growth factor 3. It occurs in every
15,000 to 40,000 births, but if both parents have the gene, one child in four will inherit two copies,

will not be affected. Two in four will inherit one copy and have dwarfism, the same characteristics

limestone cave in Flores, Indonesia changed the way people today view much of the timeline of
early human evolution. The island of Flores was assumed to have never been connected to any
mainland, bringing to question how this species arrived on the island in the first place as well as
what the island looked like at the time. There were several physical characteristics such as leg length
and brain size that made the discovery of Homo floresiensis so special. The bones found were dated

There are many types of disorders and diseases caused by a mutation in the human genome, a
fundamental building block of DNA. Achondroplasia has been classified for a long period of time,
but it was only around twenty years ago that the cause was discovered. This disorder happens to be
caused by a simple change of base in an autosomal chromosome. This is commonly a transitional
mutation that causes a simple change in protein structure. Most of the individuals with
Achondroplasia have similar mutations at a common nucleotide. Achondroplasia is a classification
of dwarfism, which is a genetic disorder that causes a mutation on an autosomal chromosome with a
change in a single nucleotide.
Achondroplasia is a common form of dwarfism that is noticed by a short stature, lowered muscle
tone, reduced extension of arm joints, shorter than normal hands and mid face hypoplasia (HUNG,
C., et.al.2008). The first classification of Achondroplasia was by Dr. Jurgen Spranger, then in 1994
the gene that was found responsible was mapped by Dr. John Wasmuth and thus found to be located
on chromosome four; that being said this fact makes the mutation autosomal (Vajo.z, et.al 2000).

The human body is an extraordinary life form of life. It is loaded with eleven distinctive control
frameworks that is utilized to direct it. One of the primary framework that is utilized as a part of the
arrangement of the human body is the skeleton framework. This framework controls the route in
which the body develops. This is performed from the diaphysis of the bones once a man quits
developing then the epysisum line will show up. In any case, what happens if the line shows up too
soon and there are development lopsidedness. A development unevenness is caused by the FGFR3
Gene. The FGFR3 quality gives guideline to making a fiber called fibroblast development factor
receptor 3. "These proteins assume a part in a few vital cell forms, including control of cell
development and division (multiplication), assurance of cell sort, arrangement of veins
(angiogenesis), wound recuperating, and incipient organism advancement. The FGFR3 protein
traverses the cell film, with the goal that one end of the protein stays inside the cell and the flip side
ventures from the external surface of the cell. This situating of the protein enables it to collaborate

Achondroplasia
Achondroplasia can be known as dwarfism which is a genetic disease which shows of a disorder in
height and bone growth . Achondroplasia is a genetic disease is a cause of Dwarfism. It occurs as a
mutation is 80% of cases. It may be inherited autosomal dominant. People with Achondroplasia
have a short stature. Identified by an adult 4"10 or under. Achondroplasia can be announced in an
ultrasound before your born there is a DNA test. The gene mutation that is responsible for
Achondroplasia is FGFR3. It is autosomal passed down from parent if with the abnormal gene. The
parent often may have the disease. It can develop from new mutations in the dominant affected
gene. FGFR3 is a protein called fibroblast growth factor receptor.

Dwarfism
"Dwarfism is short stature that results from a genetic or medical condition. Dwarfism is generally
defined as an adult height of four feet ten inches or less. The average adult height among people
with dwarfism is four feet."
Dwarfism is generally divided into two broad categories: Disproportionate Dwarfism (DD), some
body parts are small and other larger, and Proportionate Dwarfism (PD), all parts of the body are
smaller than an average person's but are proportionate. Most people with dwarfism have DD which
means they have an average sized trunk and very short limbs, but some people have a very short
trunk and shortened but larger limbs. The head may also be overly large compared to the body.
A person born with PD may ... Show more content on Helpwriting.net ...
These little people have delayed or no sexual development during adolescence and a slower growth
rate than expected for age.
Diagnosing a child with dwarfism is based off of height measurements, usually performed at annual
well child exams, but if dwarfism is suspected the doctor may want to measure more often than
yearly. The doctor will watch the physical appearance of a person for skeletal and facial signs, and
most likely take x–rays to check skeletal abnormalities. Other diagnostic tests include genetic
testing, but this may not be necessary, and hormone tests to assess the levels of growth hormones
and of course and extensive family history to see if the average height in a person's family is of
short stature.
Treatment options include surgical procedures that may correct the bones in little people like,
dividing a limb bone, straightening it and inserting metal plates to hold it in place. Another
procedure is inserting rods or staples to help correct the shape of the spine.
Some people decide to undergo limb lengthening surgery. With this procedure, the surgeon divides a
long bone into two or more sections, separates the sections slightly and braces the bone and limb
with external metal "scaffolding." Pins and screws on this frame are periodically adjusted to keep
tension between the sections, enabling the bone

Dwarfism
Dwarfism is a medical condition that affects roughly one in every ten thousand children born in
America. The Little People of America defines dwarfism as male or female adult to attain a height
of four feet ten inches or shorter. The most common type of dwarfism is Achondroplasia. Dwarfs, or
little people, still live fairly normal lives.
Most dwarfism–related conditions are genetic disorder, but the causes of some are unknown. Most
occurrences result from a random genetic mutation in the mother's egg or the father's sperm rather
than from either parent's complete genetic makeup. Achondroplasia is the most common type of
dwarfism. Infants born with achondroplasia typically have an arched skull to accommodate an

About half of infants with this type of dwarfism are born with an opening in the roof of the mouth
and also deformed ears.
Living with dwarfism is not only about being tinier than everyone else. People with dwarfism are
limited not only medically by various complications but also by the world around them built for
much larger people. In many every day life situations, dwarfs meet difficulties related to the height
of furniture, service counters, ATMs, store shelves, along with steps in buildings or public transit.
They are more likely to get fatigue from walking long distance, and also tend to get mean looks,
discriminatory attitudes, constant prejudice, and sometimes insults. Through organizations such as
Little People of America, little people are coming together socially and politically to challenge
stereotypes, to educate Americans, and provide support. There are many treatments that can be
given, but most dwarfism treatments don't increase stature they may just correct problems caused by
complications. One way to correct people with dwarfism is surgery. Surgical procedures that may
correct problems in people with dwarfism include correcting the direction in which bones are
growing, correcting the shape of the spine, and increasing the size of the opening in bones of the
spine to relieve pressure on the spinal cord. Another type of treatment is limb lengthening. This
procedure is controversial for many people with dwarfism because there are

There are many differences between an average height person and a little person. Physical health,
socializing and family all play key roles in exhibiting variances between an average height person
and a little person. People are viewed in many ways in this society, but it is all about how each
person perceives one another. Naturally as human beings "one" tends to judge others loosely, based
on multiple differences. One common misconception about both groups of people is medical issues.
For example, when an average person becomes pregnant they have the choice of giving birth
naturally or having a cesarean performed. On the other hand a little person may only have a

When a little person gets out of a car, people seem to be curious to know why there is a car, full of
people of average height getting out and how a little person is driving. Society tends to think a little

interactions, for a short statured person, one can be the first to be recognized in a crowd. An average
person also has attributes that make them recognizable in a crowd. Have you ever heard of dwarf

37. Hominin Migration Report
With knowing that this creature was so clearly not a H. sapiens, it leads us into the bigger question
of how did this hominin become dwarfed when compared to other late Pleistocene hominins. This
brings in the question how we should approach assigning taxonomy. Early on, there was argument
for creating a whole genus to place H. floresiensis because the explanation for their existence was
complicated. (Aiello 2010) H. floresiensis's height and body portion of long arms and short legs
appear to more similar to that of the much older Australopithecines. But as know from our current
understanding of the early hominin migration, Australopithecines have never made it out of Africa.

floresiensis have also been found in Liang Bua Cave. (Morwood 2005) If we follow our conclusions

we can conclude that there was indeed belonged to a population of earlier hominins present before
H. floresiensis. Despite all this evidence for a H. erectus origin, there an issue of the details which

floresiensis debate is pinning one of these subspecies as the origin species. In doing this, we hope
create a better understand for H. floresiensis's relation for the other members of the Homo genus.
But if we truly look at the genus of Homo critically, it doesn't take much for us to see that the genus
itself is yet to perfectly defined. It the recent times, there has been a lot of changes to ideas we use
to define a member of the genus Homo. There has been debate on where to change the name of our
H. sapiens. The idea would be to define the current modern day human as a subspecies. For now,
Homo appears to be an umbrella term with species under it that serve as their umbrella terms. This
brings to the question of whether H. floresiensis is subspecies of H. erectus due the fact it displays
similar morphologies. H. floresiensis could easily bear the name Homo erectus floresiensis, but this

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.

80% of achondroplasias have normal sized parents, which mean that their parents have the genetic
disorder dormant in their bodies. (News Medical, March 28, 2014.)
There are two broad types of achondroplasia: Proportionate and disproportionate. Disproportionate
achondroplasias have short legs and arms with a long core while proportionate achondroplasias are
just small all over. ( News Medical, March 28, 2014.)
Achondroplasia is the most common form of dwarfism. 1 out of 26,000 to 40,000 babies have
achondroplasia and it is noticeable at birth. People with achnodroplasia are characterized by having
small arms and legs, a small body, and sometimes crowded teeth. A less common form of dwarfism
is Spondyloepiphyseal Dysplasias (SED). About 1 in 95,000 babies get this form of dwarfism. They
are usually characterized by a shortened trunk, club feet, and weak hands and feet. The most rare
form of dwarfism is Diastropic Dysplasia. This occurs in about 1 in 100,000 births. People with this
type usually have shortened forearms and calves, deformed hand and feet, limited range in motion,
and a cleft palate. (Webmd, April 8, 2005, March 28, 2014.) To be considered a dwarf, the height of
the person must be 4 feet 11 inches and under.
