Syndromes

Myelodysplastic syndromes, also known as MDS and pre-leukemia, are a group of disorders caused when the production of white blood cells, red blood cells, or platelets is interrupted (Myelodysplastic Syndrome Treatment 2016). These syndromes are rare, fewer than 14,000 cases of myelodysplastic syndromes occur in the United States each year (Statistics about Myelodysplastic syndromes). Blood cells and bone marrow do not fully develop or become mature enough to function properly when a person has…

Down syndrome or trisomy 21 is caused by having an extra copy of chromosome 21 and it is a developmental disorder which means having three copies of each genes rather than two, this extra copy changes several characteristics and leads to physical and mental issues for the child. Anyway, what are the signs and symptoms of Down syndrome? Different complications at different times of lives may happen to people with Down syndrome as well as the signs of Down syndrome can vary from one person to…

Down syndrome? Risk Factors and Research Bria Williams Valencia Community College, East Campus Author Note This paper was written for Human Biology, Section 24630, taught by Professor Ed Schultz. Abstract In 1866, John Langdon Down; an English physician, recorded and published an accurate description of a person with Down syndrome. He stated that, the facial features of those who have Down syndrome were similar to those of the Mongolians and he called them mongoloids. Down syndrome,…

Down syndrome is a mutation that occurs when an individual has a partial or full extra copy of chromosome 21. The additional chromosome changes the course of development and causes the well known characteristic changes associated with down syndrome. A few of the common physical traits of down syndrome are small stature, low muscle tone, and an upward slant to the eyes. However, each person affected with down syndrome is unique and may possess these characteristics to different levels. Down…

Asperger Syndrome (AS) is a one of five autistic spectrum disorders. AS is also recognized by some as a neurological disorder. Sufferers of this syndrome share many of the same characteristics of autism except the accompanying disabilities. The syndrome can exhibit a variety of characteristics ranging from mild to severe. Those afflicted with AS have difficulty understanding what people around them think and feel. As a result, they often behave inappropriately in social situations or do…

“Down syndrome is a genetic disorder caused when abnormal cell division results in extra genetic material from chromosome 21. This genetic disorder, which varies in severity, causes lifelong intellectual disability and developmental delays, and in some people it causes health problems. Down syndrome is the most common genetic chromosomal disorder and cause of learning disabilities in children.” ("Down Syndrome - Mayo Clinic") History: Down Syndrome was discovered in 1866 by a British…

Mr. Knapp Human Disorders: Down Syndrome In the world we live in today, we are faced with many human disorders originating from the time a person is a fetus to the time of birth. These disorders can be caused by a number of factors, ranging from the exposure of the parents or even the victim to harmful chemicals or radiation, for example in the case of the chemical attack in Vietnam, to the acquisition of less or extra chromosomes. Down syndrome is one of the most common natural…

been diagnosed with Down Syndrome. People born with this condition often struggle with health issues and social skills. Down’s is a chromosomal disorder that causes lifelong health and intellectual issues depending on its severity. Unfortunately, “Down syndrome is the most common genetic chromosomal disorder and cause of learning disabilities in children” (Mayo Clinic Staff). It not only influences how one functions and communicates in everyday life, but Down Syndrome also affects parents and…

Angelman Syndrome (AS) is a genetic disorder of the ubiquitin-protein ligase E3A or UBE3A on the 15th chromosome. If this is gene damaged or lacks the maternal allele for UBE3A contributions, it results in Angelman Syndrome (Mary 2011). This disorder was first discovered in 1965 by an English pediatrician known as Dr. Henry Angelman. Angelman studied children with similar motor disorders, facial abnormalities and a happy demeanor. He named this disorder "Happy Puppet Syndrome" after observing a…

Will Turner’s syndrome be able to be mitigated in the next 10 years? DIAGNOSIS AND OCCURANCE Turner’s syndrome is a chromosomal condition which occurs in women due to an incomplete meiotic division. It results in the sex chromosome being incomplete and results in an ‘XO’ in the 23rd pair instead of the regular ‘XX’. This results in the birth of a female with Turner’s syndrome – resulting in a short stature, infertility, heart defects and learning disabilities. As Turner’s syndrome is due to an…
