The 1930's Down Syndrome

Down syndrome is a genetic disorder that numerous individuals around the world suffer from; it is an intellectual disability that is caused by having one too many chromosome 21 copies, trisomy 21. The average person has two copies of chromosome 21 in each cell, whereas, an individual with Down syndrome has an extra copy of chromosome 21. This happens when either the sperm or egg cell undergoes atypical cell division during development. In the United States, there are approximately 400,000 individuals who have been diagnosed with Down syndrome, according to the last census in 2012 (National Down Syndrome Society).

Returning to Mexico after seventeen years of living in the United States gave me an overwhelming sense of nostalgia. Walking down the streets of San Cristobal de las Casas, Chiapas, had a familiar feel, like being home. San Cristobal de las Casas, which is a relatively small city in the highlands of Chiapas, is plagued with poverty rooted in its colonial history. Many streets bustle with people from all over the world near the zocalo, which is a public plaza in the center of the city filled with coffee shops, intellectuals, indigenous children, and adults. As you walk by you can overhear people speaking in unfamiliar languages. While sitting outside at a coffee shop I became

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 aetiology of Downs syndrome which means the cause of a specific disease (Mcferran, 2014). Suggests that when one of the chromosomes in reproduction do not separate properly this is when Down’s Syndrome is caused (Steven, 2005). This extra chromosome causes physical developmental defects this causes reduced muscle tone, a small mouth with a projecting tongue and eyes that slant downwards and upwards and causing the back of their head to be flat. Many babies born with Down's Syndrome are diagnosed with the condition after birth and are likely to have many physical defects for example they may have reduced muscle tone, eyes that slant upwards and outwards, a small mouth with a protruding tongue and a flat back of the head. (Hartley, 2015). Down Syndrome patients can also be afflicted with other conditions, including heart disease, Alzheimer’s disease, and leukemia (WHO, 2010). This could effect children and adults through out their life also effecting their physical and mental health.

The genetic disorder of Trisomy 21, or Down syndrome is one that has often interested me. I understand that many children born with his genetic disorder can in fact live a full life, often with assistance. When answering the question of what exactly Down syndrome is, a good definition can be one describing this disorder as a genetic condition where a person has an extra 21st chromosome. The typical person has 46 chromosomes, therefore the person born with Down syndrome has 47. This extra chromosome brings with it some physical and cognitive characteristics that include mild to severe cognitive delay, low muscle tone, stunted growth, an easily identifiable upward slant to the eyes, generally a deep crease across the center of the palm and the appearance of a flat face. We have to keep in mind however, that each person with Down syndrome is an individual and might have some of these characteristics to different degrees, or possibly none at all.

Down syndrome is caused by a person having three copies of chromosome 21 instead of two copies. Down syndrome is also known by another name called trisomy 21. In the picture above it shows a genetic analysis of a person with down syndrome. If you notice in the picture there are 2 sets of chromosome except for the 21st chromosome set there is a pair of three. This is important to notice because chromosome sets are supposed to be in sets of two. It's a fact that the three chromosomes in set 21 are what causes down syndrome. Every cell in a person with down syndrome will contain 47 chromosomes instead of 46 chromosomes. “There are many theories that may be the cause of having an extra cell to react inside the chromosome that causes down syndrome

A tropical wave emerged into the Atlantic from the west coast of Africa on September 14. After detaching from the Intertropical Convergence Zone (ITCZ) on September 18,[7] the wave quickly developed into a tropical depression about 575 mi (925 km) west of the Cabo Verde Islands.[3] Moving northwestward, the depression intensified according to ships and satellite imagery,[7] becoming Tropical Storm Faye on September 19.[3] The cyclone then moved westward and was unable to intensify further due to increasing wind shear,[7] before weakening to a tropical depression on September 23.[3] Shortly thereafter, Faye turned to the north, crossing an upper trough axis over the central Atlantic. Southwesterly flow aloft allowed the system to re-strengthen,[7]

Down syndrome (known as Trisomy 21) is a genetic disorder caused when cell division results in extra genetic material from chromosome 21. This genetic disorder occurs in about 1 of 800 live births. Down syndrome was first characterized a separate form of mental disability by John Langdon Down in 1862. By the 20th century the disability had become the most recognizable form of mental disability. These individuals have gone through a lot. In ancient times, many infants with this disability were killed or abandoned. The people with Down syndrome used to be called Mongolian idiots and the syndrome was called mongolism. This comes from the people thinking that Down syndrome individuals resembled Mongolians. It doesn’t only affect the individual

I intend to enroll in Midland University and participate in their Honors Program. Through the Honors Program I will receive heightened learning in subjects such as biology, chemistry, psychology, and math. More challenging curriculum would facilitate personal and academic growth that will prepare me for my pursuit of further difficult opportunities. Additionally, I will receive opportunities for internships and experiences that will further my knowledge of the natural world. I will major in biology with a concentration in veterinary medicine.

For this reason, routine screening of newborns for sickle-cell anemia is currently carried out in more than 40 states within the United States. Down Syndrome Down Syndrome, which used to be called mongolism, is a congenital malformation accompanied by moderate to severe mental retardation, is caused by a chromosomal abnormality. People with Down syndrome are often short in height and have a small, round head with a high, flattened forehead and split, dry lips and tongue. A typical feature is a fold of skin, the epicanthic fold, on either side of the bridge of the nose. The palms show a single transverse crease and the soles have a straight crease from the heel to the space between the first and second toes.

Down syndrome is a genetic disorder in which a person is born with an extra copy of chromosome 21. There are three genetic variations that cause Down syndrome: Trisomy 21, Mosaic Trisomy 21 or Translocation Trisomy 21. There are many ways in which theses disorders affect the body.  Trisomy 21 occurs when an egg or sperm comes in with an extra copy of chromosome 21, then, once an embryo is formed and starts to develop, the chromosome is replicated in every single cell of the embryo. Trisomy 21 is the most common type of Down syndrome. About 92% of Down syndrome patients have this type. People with Trisomy usually have physical problems.

Down Syndrome is a genetic disorder that occurs when a persons 46 chromosomes abnormally divides into 47 chromosomes, creating a full or partial 3rd copy of the chromosome 21.

Down syndrome is a disease in which chromosome 21 has extra genetic material delaying the way a child develops mentally and physically.

The possessor of this genotype has the genetic disorder called Down syndrome. Down syndrome is caused by this person having chromosome 21, which is also called Trisomy 21. There are different things you see in people with Down syndrome such as, different physical and mental traits. This genetic condition varies between each person with this genetic disorder. They all have similar features, but do not look the same.

. Down syndrome is not a disease that someone catches and is not caused by difficulties during the pregnancy, it is a genetic condition. This condition is caused by the presence of an extra chromosome in the body’s cells and causes a redundant amount of proteins to be formed. All cells of the body derive from a single cell formed by the fusion of a father’s sperm and a mother’s egg. Each cell carries a nucleus full of genetic material known as genes. These genes are inherited from both the mother and father. Each cell normally contains 46 pairs of chromosomes. 23 chromosomes come from one parent and 23 from the other, hence the 46 pairs. When it comes to children with down syndrome, one of the chromosomes does not separate properly and so the
