1. History of the Patau Syndrome
Patau Syndrome, otherwise known as T13 is a very rare and lethal genetic disorder in which a
person has three copies of chromosome 13 instead of two. T13 is characterized by the presence of an
assortment of heart and brain malformation in newborns. Children with the disease are often born
with multiple birth defects that are normally associated with T13 but not limited to it, including
small eyes, undescended testicles, cleft lip/palate, and they consistently exhibit signs of mental
deficiency and/or retardation. Approximately 1 in 10,000 newborns are born with Patau Syndrome
each year.
I choose this rare disease because not only is it unheard about but the present dilemma plaguing the
medical field on whether or not a child born with this disease should be given adequate care for
survival is shocking. Everyone deserves to be administered the best possible treatments available
regardless of what their "quality of life" is determined to be. Examining the physiological aspects
and treatments available for T13 show that there should be no standard to which children born with
the disease should be given higher priority with treatment based on severity.
Clinical Perspective
History
In 1656, Thomas Bartholin described developmental birth defects characteristic to those present in
newborns diagnosed with T13, only in that time is referred to as cytogenetic syndrome. It wasn't
until 1960 that German physician Klaus Patau discovered the underlying genetic cause by looking at

Chromosomes contain genetic information that is passed down from the parents to the child. The
possibility of a mistake during cell division rise as a woman ages, therefore; the chances of
chromosomal dysfunction increases. "All genetic abnormalities increase as the egg gets older."
(Cohen, and Bonifield) Each female is born with a certain amount of eggs, these eggs do not
multiply and you cannot add more. During each menstrual period a female loses one of her eggs,
and these cannot be replaced. As a female gets older so does her eggs, therefore, during the division
of cells it leaves a lot of room for mistake. If the chromosome pair does not split and separate the
egg will have 24 chromosomes not the 23 that are needed. The difference of only one chromosome
can change the faith of the child from being normal to having down syndrome. "In the 1st trimester
miscarriages occur because of chromosomal abnormality in the fetus." ("Childrens Hospital of
Philadelphia") As a result, older woman have a much higher chance at some chromosomal disorder
when they are having children at an older age. "Down syndrome is a genetic disorder caused by an
error in cell division." (Cohen, and Bonifield) As explained above, it is the

If an archaeologist were to go into my room they would discover a silver ring that sits on top of a
bookshelf. The ring is small, about a size six. Halfway through, the band is interrupted by two hands
with cuffs holding a heart with a crown on it. The design is very detailed. The cuffs aren't perfectly
square, they're a little wider on the side distal to the hands. Five ridges about one centimeter apart
are on the cuffs. A protruding ring separates the cuffs and hands. The first four fingers hold the
bottom of the heart while the thumb holds the top of the heart. Each finger ends in a small fingernail
marked by a half circle. A lot of detail is used to differentiate each finger and fingernail. At its
widest part, the heart is about one centimeter ... Show more content on Helpwriting.net ...
Based on the archaeologist's observations, it can be assumed that the ring was worn often but they
wouldn't be able to confirm that I wear this ring everyday or that it is actually a special type of ring
called a Claddagh ring. Nor would they be able to determine just how important this object is to me.
One of the reasons that this ring is so important to me is because it connects me to my Irish heritage.
Claddagh rings are a type of traditional Irish ring. I am fourth generation Irish and very in touch
with my heritage. Practicing tradition is very important to me and this ring itself has so much
meaning in it. The hands represent friendship, the heart represent love and the crown represents
loyalty. Depending on how one wears the ring their relationship status is represented. By wearing
the ring on your left hand with the bottom of the heart facing your palm you are saying that you are
married, whereas if you wear it on the same hand but with the bottom of the heart facing your
fingertips you're no longer saying you are married but engaged. You are representing that you are in
a relationship if you wear it on your right hand with the bottom of the heart facing your palm but if
the bottom of the heart is facing your fingertips that means you're

Trisomy 21 also called Down syndrome, is an abnormality at a chromosome level and is believed to
be the most prevalent genetic impairment (Bukato & Daehler, 2012, p. 89). Compared to other
children with related mental development, a child with Down syndrome has academic impairment
such as language and memory, their physical development is considered slow, and they possess
unique traits. Some of these traits consist of almond shaped eyes, a flattened facial feature, broad
hands, and an unusual crease in the center of the palm. Physical development is considered slow
which results in being short in stature, height, and poor muscle tone. This syndrome causes poor
vision including cataracts and other eye problem, immune system deficiencies. Forty percent ...

The preposition of cells seems to exhibit the severity of trisomy. The age of the parents seems to
increase the contributing aspect to Down syndrome. Women thirty–five and older have given birth
to sixteen percent of babies, which over half were born with Down syndrome. Expects have
conducted different experiments to try and explain this, the first being the "older egg" hypothesis.
With age the ova either changes due to time or for the reason of increased exposure to potentially
hazardous biological and environmental conditions (p89). During ovulation the egg cells being
released in later childbearing aged women are more susceptible to chromosomal errors as most are
undergoing the last stages of meiosis. Other expects have a hypothesis of the "relaxed selection",
which shows older mothers, contrary to younger mothers, are less likely to unconsciously terminate
the fetus with trisomy 21 chromosomes. Another view is egg cells with the extra chromosomes are
less likely to be selected but as the women ages more egg cells with extra chromosomes are present
and there are more to choose from. The age of the father can also be a

9. A Short Note On 13, And Patau Syndrome
Trisomy 13, or Patau Syndrome, is caused by the presence of three chromosome copies on
chromosome 13. An extra copy of chromosome 13 causes the majority of cases. Some cases are
caused by a Robertsonian translocation between chromosome 13 and other autosomes such as
chromosomes 15, 21, and 22. According to Bishra & Clericuzio "Trisomy 13 is the third most
common autosomal trisomy, with an incidence of 1 per 10,000" (Bishara & Clericuzio, 2008, p. 30).
It is comprised mainly of defects of the eyes, nose, lips, forebrain, holoprosencephaly, polydactyly,
and narrow hyperconvex fingernails, and skin defects of the posterior scalp. The median age of
survival is seven days, with over 90% of affected patients dying within the first year of life (Jones &
Casanelles, 2014). Common causes of death include cardiac arrest, complications of congenital
heart disease, and pneumonia. Those that survive the neonatal period have an average length of stay
in the neonatal intensive care unit (NICU) of 10 days. According to studies, almost one quarter of
patients have at least one type of surgery in the neonatal period. More than half of fetuses with
trisomy 13 spontaneously abort. Most survivors have severe intellectual disability, seizures,
developmental delay, and failure to thrive. The incidence is slightly higher in females compared to
males.
The etiology of this disorder is trisomy of chromosome 13. Although most children do not survive

11. Myelodysplastic Syndrome
People who have Myelodysplastic Syndrome may not experience symptoms at the beginning of the
disease. However, there are three main signs that can develop and alert healthcare providers that
something is wrong. One of these is a low red blood cell count, or Anemia. Most patients that have
myelodysplastic syndromes exhibit this indicator when first diagnosed. A normal red blood count
can vary between 4.0 and 6.1 million red blood cells per microliter of blood in the body, depending
on the age and sex of the patient. A red blood cell count lower than normal is characteristic of
Anemia (Cafasso, Jacquelyn, and Gotter). Not only is Anemia shown by constantly low hematocrit,
but it can also be characterized by constantly low hemoglobin. A normal hemoglobin count is
between 12.0 and 15.5 grams per deciliter of blood for females, and 13.5 to 17.5 grams per deciliter
of blood for males. Levels lower than these show a low hemoglobin level (Mayo Clinic,
Hemoglobin Test). Hemoglobin is the protein in blood that carries oxygen to the different tissues in
the body. ... Show more content on Helpwriting.net ...
A person with a normal platelet count has between 150,000 to 450,000 per each microliter of blood
in the body. With Thrombocytopenia, patients have platelet counts that are less than 150,000 per
microliter of blood. Platelets help to promote blood clotting. When a person receives a cut, or injures
themselves, platelets come to the site of injury and bind to damaged vessel, thus causing a blood clot
and helping to stop the bleeding that accompanies the injury (Williams). However, with a reduced
platelet count, this function can be impaired. Patients can easily bruise or bleed due to even a slight
bump, as well as experience nosebleeds. Bleeding gums are another symptom of Thrombocytopenia
(MDS Foundation). Based on symptoms, doctors might decide to test a patient for Myelodysplastic

13. Characteristics Of A Chromosomal Disorder Essay
A chromosomal disorder is caused by an abundance or reduction of genes on the chromosomes. This
type of disorder may also be caused by structural changes within these chromosomes; this is known
as an aneuploidy (Porth, 2015). The most common chromosomal disorder is Down syndrome of
which there are three types: complete trisomy 21, translocation, and mosaicism (Porth, 2015). Since
its first identification in 1866, researchers have become more knowledgeable about the etiology of
Down syndrome. When one studies etiology, pathogenesis, and clinical manifestations of Down
syndrome, he or she will begin to understand multiple chromosomal disorders. Typically, the
nucleus of each cell stores forty–six chromosomes. Half of these chromosomes derive from each
parent cell. However, in those with Down syndrome, the cells contain forty–seven chromosomes.
Researchers' knowledge of the etiology of Down syndrome has grown since it was first described in
1866 by John Langon Down (National Down Syndrome Society, 2012). According to the National
Down Syndrome Association (2012), 95% of the Down syndrome cases are caused by a fault in cell
division. Although it is clear that this disorder occurs because of an alteration during cell division,
the cause as to why this occurs is unknown. However, the pathogenesis of this disorder is clear. The
pathogenesis of this disorder begins with nondisjunction during meiosis, which is failure of the
chromosomes to separate. Today, it is known that there

Down Syndrome is the most common genetic disorder in the United States. It was first described in
1866 by John Langdon Down. The actual cause of Down Syndrome or Trisomy 21 was discovered
in 1959. In the United States 1 in every 800 kids will be diagnosed with
Down Syndrome. That's about 6,000 kids born with down syndrome every year. The life expectancy
of people with Down Syndrome varys. In 1910 a baby with Down Syndrome wouldn't live until 10
years old, but today someone with Down Syndrome can live to 60 and beyond.
There is no actual cure for Down Syndrome, but there is treatment that will with help a person

The main risks are hearing problems, eye problems, heart diseases, Leukemia and other cancers, and
finally mental retardation. The reason there are so many conditions that come with Down Syndrome
there is a high chance of premature death. There are three types of Down Syndrome, Trisomy

splitting of the cells of meiosis. In Translocation there are still 46 chromosomes but another 21
attaches to another chromosome, usually 14. The extra 21 is what causes Down Syndrome. Then

17. Congenital Condition Of Congenital Heart Defects
INTRODUCTION Congenital Heart Defects (CHDs) include all structural anomalies of the heart
and the intrathoracic great vessels resulting from the errors in morphogenesis, during development.
The incidence of CHDs among live births is estimated to be 3.7 to 7.7 per 1000 (Ferencz et al.
1985). CHDs are etiologically heterogenous and it could be due to genetic (single gene defects,
chromosomal abnormality) and or environmental (multifactorial, teratogens) or unknown factors
(Michels and Ricardi 1990). From literature, it is seen, that 6 percent of CHDs are due to
chromosomal abnormality (Greenwood et al. 1975). Conversely, the reported incidence of CHDs
among individuals with chromosomal abnormality is around 30 percent. Objectives: In this paper, it
is aimed to find out the occurrence of the chromosomal abnormality and its association to CHDs in
consecutively referred patients to Division of Human Genetics, St John's Medical College,
Bangalore. MATERIAL AND METHODS A total of 65 patients with CHDs were referred for
karyotyping and counseling, during a period of 5 years. There were 33 male and 32 female patients
and their age ranged from neonate to 16 years. Patients' details were recorded in a proforma.
Chromosomal preparations were done from the modified leucocyte microculture method (Arakaki

19. One Of The Most Common Types Of Down Syndrome
Cells are the basis for human life. During conception, a sperm cell joins a fertile egg to begin the
process of procreation. Contained in the nucleus of these cells are a threadlike structure made up of
acids and proteins called chromosomes which carry genetic information. Each human cell contains
23 pairs of chromosomes in each cell for a total of 46 chromosomes (Wiseman et al., 2009). When a
sperm cell with 23 chromosomes and an egg with 23 chromosomes unite, they begin to form a fetus
with appropriate genetic makeup. In some cases, however, sperm cells and eggs have extra
chromosomes which result in genetic disorders. Down syndrome is one of the most common genetic
disorders in humans and is the result of an abnormality of chromosome 21 (Patterson, 2009). ...

The deficiency is named after John Langdon Down, a doctor who first described the condition in
1866 (Hickey et al., 2012). There are several ways Down syndrome occurs. The most common type
of Down syndrome occurs when chromosome 21 fails to separate during development, producing an
additional copy of chromosome 21 called trisomy 21. During formation of sperm and egg cells,
chromosome 21 fails to separate, which produces the additional chromosome 21, and the cell
contains 24 total chromosomes. When the affected cell is joined with a normal sperm or egg the
fetus has 47 chromosomes with three copies of chromosome 21 (Patterson, 2009). The origin of the
additional chromosome 21 comes from the mother about 88% of the time, 8% of the time from the
father, and 3% after the sperm and egg cell have joined (Natoli et al,

21. Turner Syndrome : A Chromosomal Disorder
Turner Syndrome
Shinji Lin
December 15, 2015 Period 5
Turner syndrome is a chromosomal disorder that affects development in females. This condition is
caused by a missing or incomplete X chromosome. In 1938, Henry Turner, an American
endocrinologist, described seven women with short stature, lack of sexual development, neck
webbing (extra skin on neck), low hairline, and cubitus valgus (arms that turn out at the elbow).
Years earlier, Otto Ullrich, a German geneticist, independently described an 8–year–old girl with
short stature, swelling of the hands and feet, neck webbing, and several other features now
associated with Turner syndrome. In the 1940s, endocrine and pathology studies confirmed that the
sexual immaturity seen in these patients was due to ovarian failure. In 1954, Paul Polani and his
colleagues provided the first link between Turner syndrome and sex chromosome abnormality when
they reported three patients with this condition who were sex chromatin negative. With the advances
in chromosomal analysis, it was revealed that Turner syndrome was associated with the presence of
a single X chromosome. Other names used to refer to this disorder include TS, monosomy X, and
Ullrich–Turner syndrome. Normally, a female inherits one X chromosome from each of her parents.
However, girls with Turner syndrome do not have two complete X chromosomes. Approximately
half of individuals with Turner syndrome have monosomy X, which means each body cell has only

There are three main types of chromosome abnormalities that can occur with Down syndrome,
which are trisomy, translocation, and mosaicism.
Trisomy occurs when a child has an extra 21 chromosome known as trisomy 21. This means that a
child with Down syndrome has forty–seven chromosomes in each cell, instead of the normal
number of forty–six chromosomes. This form of chromosome error, trisomy 21, is found in about
ninety five percent of persons with Down syndrome. In three–four percent of people with Down
syndrome, the second type, translocation occurs. Translocation happens when an extra 21
chromosome is attached or translocated on to another chromosome. With this type in one–third of
the cases a parent is the carrier of translocation and that is why it is important to examine the
parents' chromosomes. The last chromosome abnormality is mosaicism. This type results from an
error in cell division soon after conception and with it some cells have forty–seven chromosomes
while others have forty–six chromosomes. However, only one percent of individuals has this type of
chromosome abnormality (Moss).
Although having a child with Down syndrome may be difficult at times, education is important for a
child with Down syndrome to be able to prosper in life. Although the vast majority of children with
Down syndrome function in the mild to moderate range of mental retardation they have many

syndrome it may be possible to retrieve sperm by TESE. (68) Several pregnancies have been
achieved with testicular sperm used for ICSI. The embryos show normal or aneuploid karyotypes
which can be identified by preimplantation or prenatal diagnosis. Interestingly, the birth of normal

27. Three Different Types Of Down Syndrome
Down syndrome is a common disorder that affects many people across the globe. In fact, Down
syndrome is the most common genetic birth defect. Down syndrome affects over 400,000
individuals in the United States alone. Down syndrome always affects the 21st chromosome in a
certain way. The normal amount of chromosomes that a person has is 46 chromosomes, but most
commonly, a patient with Down syndrome has 47 chromosomes. Down syndrome is a disorder that
affects the 21st chromosome, causing intellectual impairment and physical abnormalities. There are
three different types of Down syndrome: Trisomy 21, translocation, and mosaicism. About 90–95%
percent of people with Down syndrome have Trisomy 21. Trisomy 21 is when an extra copy of the
21st chromosome is formed. Translocation is when a part of the 21st chromosome is broken off and
attaches itself to another chromosome. Mosaicism is when only some of the cells in the body are
affected by Trisomy 21. Down syndrome can cause delayed development, upturned eyes, a learning
disability, s short stature, a speech delay, a simian crease, and a displacement of the tongue. Some
ways to test if an individual has Down syndrome is when a child is in the womb and an
amniocentesis, chronic villus sampling, or a cordocentesis are performed. An amniocentesis is when
some of the amniotic fluid id sampled. A chronic villus sampling is when a sample of the placenta is

Approximately three to four percent of babies born every year are born with some kind of genetic
disorder. A genetic disorder is described as an illness caused by an error in one's genome, and is
usually hereditary. To understand how these errors occur, one must first understand the basic
concept of genes. Genes are the basic units of heredity and are made up of pieces of DNA that
instruct the cell how to make specific proteins. Humans are estimated to have about 20,000 to
30,000 genes in their genome. Chromosomes contain these genes and DNA. Humans have 23 pairs
of chromosomes or a total of 46 chromosomes. One pair of these chromosomes determines the sex
of a person while the other 22 are autosomal, meaning that they determine the rest of ... Show more

This event is called nondisjunction. Down Syndrome is the most common example of a trisomy
chromosomal abnormality among humans. An individual who suffers from Down Syndrome, also
known as Trisomy 21 would have three copies of chromosome 21 instead of the usual two, resulting
in a
total of 47 chromosomes. Those who suffer from Down Syndrome have intellectual disability and
are usually marked by short stature, short, stocky arms and legs, flattened facial features, slanted
eyes, and other symptoms that range in severity depending on the person. An example of a
monosomy chromosomal abnormality would be Turner Syndrome. Turner Syndrome only occurs in
women and is caused by monosomy X, which is an absence of that entire sex chromosome, leaving
only 45 chromosomes. Women affected by Turner Syndrome usually have normal intelligence but
are characterized by their short stature, loss of ovarian function, and sometimes a webbed neck or
swelling of hands and feet. The second type of chromosomal abnormalities is structural
abnormalities. These include abnormalities due to deletions, duplications, translocations, inversions,
or rings. Deletions are when a part of a chromosome is either missing or deleted. An example of
disorder caused by deletion is Wolf–Hirschhorn Syndrome which occurs due to partial deletion of

TS is not directly "treated" by a doctor, but the individual health concerns that arise for each girl or
woman with TS should be monitored and treated by the appropriate specialist (Turner Syndrome
Society of the U.S)." Females with TS have a normal life expectancy but it also depends on the
severity of their case and if they are receiving the medical treatment that they need to live a healthy
life. For example, girls who have heart problems due to TS must see a cardiologist. Turner
Syndrome contributes to only females because we have two X chromosomes and this disorder is the
defect of one X chromosome. There is no cure for Turner Syndrome, but therapies have been
developed that can improve physical treatment. The primary therapies for affected individuals are

This genetic material is found in the centre structure (known as the nucleus) of a cell. The human
body is made up of millions of cells, in each cell there are 46 chromosomes – half from the mother
and half from the father. out of the 46 chromosomes there are 23 pairs, one of these pairs – pair
number 23 – are the sex chromosomes which determines the infants sex – XX female, XY male. The
other 22 pairs are known as autosomes. These pairs are known as homologous chromosomes since
they contain genes for the characteristics which are the same size and length. Gametes – sex cells –
only contain one chromosome from each homologous pair, hence contain the haploid number
(N).The allele – different versions of the same gene – pair for each characteristics is called the
genotype, whereas the physical expression of the allele is the phenotype. Some alleles are dominate
and some are recessive, the dominate gene always gets past on. A genetic disorder is a disease or

Trisomy 21 is a disorder that is also considered a chromosomal abnormality because it has an extra
chromosome added. This causes the abnormality to have Down syndrome. Like in most cases of
Down syndrome are not inherited. When the condition is caused by trisomy 21, the chromosomal
abnormality occurs as a random event during the formation of reproduction cells in a parent. The
abnormality usually occurs in egg cells, but it occasionally occurs in sperm cells.
E. is it an autosome or sex linked? Explain your answer.
Answer: out of 46 chromosomes, 44 are autosomal. The remaining 2 chromosomes are sex
chromosomes. Chromosomal disorder Down syndrome/ trisomy 21: having an extra chromosome
for the 21st pair causes Down syndrome. This here would be sex linked because your sex
chromosomes are the ones who determine if you are to have the disorder. Also because your parents

1. Define Pathophysiology: Pathophysiology may be defined as the study of function of diseased
organs with application to diagnostic procedures and patient care. Pathophysiology involves the
study of functional changes in the body that result from disease processes. Pathophysiology includes
some aspects of pathology which refers to the laboratory study of cell and tissue changes associated
with disease.
2. Define Disease: Disease may be defined as an abnormal state in which the healthy anatomy
(structure) and physiology (function) of the body is not functioning normally. Moreover it can be
defined as a disruption in homeostasis–unhealthy state of body part, system, or body as a whole
where there is anatomical distortion or physiological dysfunction. ... Show more content on

ALL occurs when the cells of the bone marrow develop errors in its DNA causing it become
abnormal. This abnormality causes bone marrow cells to continue growing and dividing past when a
normal, healthy cells would. When this occurs the bone marrow produces immature cells that grow
into leukemic white blood cells called lymphoblast's which are unable to function properly and lead
to healthy cells becoming crowded and dying off. According to the Mayo Clinic childhood ALL is
one of the most common types of cancer seen affecting children (around two thirds), especially
those who have experienced previous cancer treatment, have a genetic disorder (i.e. down
syndrome), or have a sibling will ALL (MayoClinic, 2015). Factors such as age, lab results, and
response to chemotherapy treatment affect the prognosis and survival rate of those with ALL. The
younger an individual with All is the greater likelihood for recovery with proper treatment. Lab
results showing lower numbers of white blood cells have higher chances of likelihood for recovery.
Response to treatments such as chemotherapy also influence the likelihood for recovery; Depending

46. A Short Note On Pre Implantation Genetic Diagnosis
ERT – PRE–IMPLANTATION GENETIC DIAGNOSIS Cystic Fibrosis: Pre–implantation Genetic
Diagnosis (or PGD as it is more commonly called) is majorly used to test for 2 things; specifically
known genetic conditions, and chromosomal abnormality. Ultimately it allows only normal cells,
which are cells unaffected by the disorder it is testing for, to be selected and used for the IVF
process. PGD is popularly used as it maximizes the chance of having a healthy baby which is a big
health concern of potential future parents (Vitrus Health, 2016). STATISTICS PGD is performed
through a general procedure however there are three main ways that it can happen. This is through
Advanced Embryo selection (array CGH), Karyomapping and Fluorescent in Situ Hybridization
(FISH) (Vitrus Health, 2016). The most commonly used path is the Advanced Embryo Selection as
it is the most advanced and can screen for the most diseases (Hunter New England Local Health
District – Children, Young People & Families, 2016). Through these screening processes the general
procedure is as follows. The female takes medication to stimulate the ovaries into producing
multiple eggs. Once these eggs are made they are retrieved through a transvaginal needle and then
fertilized outside of the body by sperm using ICSI, which is Intracytoplasmic sperm injection, a
specialized form of IVF where the sperm is directly inserted into an egg (City Fertility Centre,
2013). The embryo is then developed in a specialized laboratory for

48. Down Syndrome : An Mysterious Genetic Condition
Brief History: Until the mid–twentieth century, Down Syndrome was considered a mysterious
genetic condition that not many scientists or common people could understand or accurately
describe. More specifically, members of the society realized that people with Down Syndrome were
different – but they could not distinguish or diagnosticate the characteristics or the causes of the
condition. Although that is true, scientists and doctors like Jérôme Lejeune, Jean–Étienne
Dominique Esquirol, and Édouard Séguin had investigated and recognized certain indicative
attributes of those with Down Syndrome. However, none of them composed a fully descriptive
study that corresponded with the lives of a majority of Down Syndrome patients. In due time, (1866)
British doctor John Langdon Down presented a comprehensive, widely acclaimed, and unrefuted
portraiture of what Down Syndrome truly resembles.
Definition:
Down syndrome is characterized as a chronic genetic chromosomal disorder which alters one's
cognitive growth, intellectual development, and physical characteristics. This extremely widespread
condition is most prominently existent in human beings whose genetic makeup is composed of an
additional copy of chromosome 21. Additionally, these human beings are known for acquiring 47
chromosomes rather than the conventional 46 chromosomes. This chromosomal abnormality is
extremely common, yet highly spontaneous. To illustrate, the prevalence of Down Syndrome is

Myeloproliferative neoplasms (MPNs) are a clonal disease of myeloid stem cells that are
characterized by myeloid cell proliferation, bone marrow (BM) fibrosis, and symptoms associated
with the accompanying peripheral blood cell abnormalities. The World Health Organization (WHO)
provides diagnostic criteria for the following MPN subtypes: chronic myelogenous leukemia; BCR–
ABL1–positive; polycythemia vera (PV); essential thrombocythemia (ET); primary myelofibrosis
(PMF); chronic neutrophilic leukemia; chronic eosinophilic leukemia, not otherwise specified;
mastocytosis; and MPN–unclassifiable (MPN–U).1 Common molecular events in MPNs are the
V617F mutation in the JAK2 gene, mutations of exon 10 of the MPL gene (mainly involving codon
W515), and ... Show more content on Helpwriting.net ...
At least 20 metaphases were analyzed whenever possible. Clonal abnormalities were defined as two
or more cells with the same chromosomal gain or structural rearrangement or at least three cells with
the same chromosome deletion. Karyotypes were recorded according to the International System for
Human Cytogenetic Nomenclature (ISCN) 2013.14
In addition, fluorescence in situ hybridization (FISH) was performed in most cases (n = 158). The
following commercial FISH probes were used in subset of patients: a BCR/ABL dual–color, dual–
translocation probe (n = 158); the 13q14 SpectrumOrange probe (n = 66); the LSI D20S108 (20q12)

Trisha Jane Lawrence was born on August 1, 2010 and weighed 31 pounds and measured 15.5
inches long. She was diagnosed with trisomy 18, but she was not expected to live very long. In this
case, Trisha wasn't able to eat because her stomach and esophagus were not connected. However,
her parents stuck to God's plan and decided against surgery to reconstruct it. Remorsefully, a year
later Trisha Jane Lawrence died peacefully in her mother's arms on August 2nd, 2011. Hence,
trisomy 18 is a rare chromosomal disorder that most likely will result in death. Trisomy 18 affects

The first possible gene is ras1 or raspberry gene. This gene is located on the X chromosome and at
9E1–9E2 on the cytogenetic map. The location on the recombination map is unknown. The ras1
gene is a possible choice due to the dark red and orange color combination that it expresses. (Nash
et al. 1994) Another gene is the Pur1 or the purplish ruby gene. This gene is located at 3–39.5 on the
recombination map. The Pur1 gene could be responsible for the mutant's eye coloration due to the
red and brown pigments that are present. (Aparisi and Najera 1990) The pr1 or purple gene is
another possible explanation for the mutant's eye color. This gene is located at 38B3–38B3 on the
cytogenetic map. It's location on the recombination map is 2–54.5. The purple gene has a high
probability of being responsible for the mutant's eye color due to the light reddish color combined
with a touch of orange and the similar texture that it possesses. (Kim et al. 1996) Another possible
gene is ry1 or rosy. This gene is located on the 3R chromosome. Its location on the recombination
map is 3–52.0. The rosy gene can be located at 87D9–87D9 on the cytogenetic map. Rosy gene is
another possibility because it possess a red shade with more orange and brown pigments that could

Its termed trisomy 21 due to the fact it's not an entire extra chromosome 21 that is responsible but
rather a small segment of the long arm of this chromosome. Only two other triomies occurs with any

21 is one of the most common human chromosomal aberrations occurring in about 0.5 percent of all
conceptions and in one out of every seven hundred to eight hundred live birth.

When the sperm cells from the father and the egg cells from the mother are formed, they both
undergo a reduction of their total number of chromosome from forty–six to twenty–three. This
process is called meiosis (which contain one–half of the chromosome number found in the original
cell before division) when a baby is conceived by the combination of one sperm cell with one egg
cell, the baby receives twenty–three chromosomes from each parent for a total of forty–six
chromosomes. Occasionally, an error occurs in the reduction process instead of passing on twenty–

63. Trismony 18 or Edwards Syndrome
Introduction Trisomy 18, or Edwards Syndrome as it is more commonly known, is a genetic
disorder in which there is a problem with cell division called meiotic disjunction. This disease is
commonly associated with the well known Downs Syndrome which is also known as Trisomy 21. A
disease with an unnatural number of chromosomes are is called a aneuploidy. Edwards Syndrome
occurs when a child is born with an extra #18 chromosome. This occurs in about 1 in 2500
pregnancies and 1 in 6000 births. There is a high mortality rate for Edwards Syndrome, half of all
children who are carried to term will be stillborn. With the survivors less than 10% will live to be a
year old, boys also having a higher mortality rate. (Trisomy 18 Foundation 2013). In this paper I
will be addressing key components to Trisomy 18 and looking more closely at a few cases of "long
living" survivors. Specifically history, symptoms, diagnosis, screening and treatment will be
examined.
History
Trisomy 18 and 13 began to appear in literature in the early 1960's. During this time both of these
diseases were considered fatal. A majority of the documented information obtained on these
chromosome disorders was gathered from case studies. Even to the current day, these are very
deadly syndromes that often kill within the first year of life but due to medical advances can now
have life sustained (Nelson 2012). In a study from 1968 some of the clinical features of Edwards

Trisomy 18 cannot be cured because you cannot fix chromosomes but only can fix the defects that
occur because of the chromosomal disorder. This disorder is a problem with the number of
chromosomes a person is born with. The 18th chromosome is half duplicated causing birth defects
and problems in their development, also allowing only for a short lifespan. This disorder is not
inherited, but instead happens randomly when the chromosomes of the mother and father combine
and a third chromosome 18 is formed. There is no known cause for why this extra chromosome
develops in the fetus. Edward's Syndrome is the second most common of the trisomy disorders,
following Trisomy 21 (Down syndrome), but does not happen very often in developing fetuses. It
occurs once in every 5,000 live–born infants, and most of these infants are female. Many times, the
fetus that is affected with this disorder will not make it the full nine months. Other times, if the
infant is born with the disorder they will only live for about a month or less. This disorder is seen
more often when older women are pregnant, rather than young mothers. 10 percent of individuals
with trisomy 18 will live past the first month, and some can even live into their twenties with severe

67. Acute Leukemia Essay
Acute–myeloid–leukemia (AML) is a myeloid neoplasm which is aggressive and arrests maturation
of bone marrow leading to an accumulation of immature cells of myeloblasts in bone marrow and
blood. AML forms a heterogeneous and complex disease associated strongly with epigenetic and
genetic changes in hematopoietic ancestors. These lead to disruptions of many signaling pathways
resulting in survival proliferation, and growth of the leukemic cells.
Normal HSC's (hematopoietic–stem–cells) reside in niche microenvironment of red bone marrow
and their function and survival is regulated here. AML is present in extramedullary–AML in the
initial diagnosis or during a relapse. Extramedullary infiltrations are common in all AML patients,

The survival rate at 5 years is much lower in older people than in younger adults. Experts say this is
due in part to the fact that the body of a young person can better tolerate strong chemotherapy drugs.
In addition, in elderly leukemia it tends to be more resistant to current treatments. If cancer does not
relapse within 5 years of diagnosis, you are probably cured.
Analysis of the prognosis without treatment:
The prognosis of patients with acute myeloid leukemia varies substantially depending on the
patient's age and the subtype of AML. The elderly, the AML related to previous, or secondary to
myelodysplasias and myeloproliferative syndrome treatments, the degree of initial leukocytosis, the
presence of certain genetic / molecular abnormalities, as well as the slowness in obtaining complete
remission, among others, parameters constitute an unfavorable prognosis.
Thus, young patients with leukemia's standard risk receiving a family member or donor allogeneic
unrelated in first complete remission have a chance of cure of up to 65%, while an elderly patient

Down syndrome is a congenital disorder resulting from a chromosome defect. Down syndrome
affects people of all ages, race, and economic status. It causes an increased risk of health problems

to depict the same features of those with Down syndrome today. In 1866, John Langdon Down was
the first to identify Down syndrome as a disorder. Before he described it as a disorder, those with
Down syndrome were killed, abandoned, or excluded from society. Many were also institutionalized
and received improper treatment because of the uncertainty of the disorder. In 1959, the French
physician Jérôme Lejeune identified Down syndrome as a chromosomal condition. Instead of the
usual 46 chromosomes present in each cell, Lejeune observed 47 in the cells of individuals with
Down syndrome.

This is where the name trisomy 21 originates. (5).
The extra chromosome in trisomy 21 results in overexpression of the genes. Although
overexpression is not noticeable in many genes, the genes that are involved in Down syndrome seem
to be quite different. In fact, not even all of the genes in the 21st chromosome need to be tripled to
result in Down syndrome. There are approximately 250 genes in the 21st chromosome, and only 20
to 50 genes need to be involved in the nondisjunction to cause the effects of trisomy 21. The small
area within the cell where genes need to be to cause Down syndrome is called the Critical Region.
(3).
There are several genes that researchers believe might be involved in causing Down syndrome.
Overexpression in genes such as CAF1A, Cystathione Beta Synthase (CBS), and GART might be
harmful to DNA synthesis and repair. COL6A1 overexpression may cause heart defects, and CRYA1
overexpression might aid in the development of cataracts. Overexpression of ETS2 may be the
cause of leukemia and skeletal abnormalities, while the DRYK overexpression could possibly result
in mental retardation. Premature aging and decreased function of the immune system may be caused
by the overexpression of Superoxide Dismutase (SOD1). It is important to note, however, that

What are the signs and symptoms of this disorder? A lot of people have heard of Down Syndrome,
but are unclear about what it truly means. Down Syndrome is when children are born with an extra

that their child will have Down Syndrome. Doctors can only make educated guesses if they believe
that the child will have Down Syndrome. The children that end up being born with Down Syndrome
will have physical features such as having a tiny neck, a fat tongue, tiny head, weak muscles, eyes
that look like raindrops, and having a flat face.
At what age do symptoms start to appear? The symptoms of Down Syndrome start to appear when
the child is just born. That is when the physical features are seen. The tiny neck, raindrop eyes, flat
