    rage from terminal to mild. Scientists have distinguished more that 9,000 genetic disorders, some of which are exceptionally rare while others are common. One such genetic disorder is Philadelphia Translocation, a possibly terminal and relatively rare genetic disorder (fewer than 200,000 people in the U.S. per year are diagnosed). Named for the city where it was discovered, the Philadelphia chromosome is thought to be acquired after birth and is formed when two chromosomes (9 and 22) switch some of their gene material forming a new chromosome.…

  • Down Syndrome Research Papers

    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, also known as Trisomy 21, is a condition where a person has been born with an extra copy of chromosome 21. Dr. Jerome Lejeune; a French physician discovered that being…

  • Edwards Syndrome Background

    The history and background of Edwards Syndrome comes from a man named John Hilton Edwards. He first wrote down his findings after a letter he wrote talking about heredity disorders. Pediatrics was his specialty and he was spending time at the Children’s Hospital in Birmingham when he saw a potential chromosomal disorder in a newborn. Edwards called it trisomy which means type unknown. Then he had some of the tissue tested and founded an extra chromosome. He then re-named named it trisomy…

  • The Negative Effects Of Down Syndrome

    Down Syndrome is the most prevalent and recognizable chromosomal abnormality in live born children, with a current prevalence of 2.8 out of 1000 children born with the genetic disorder [1]. In 1866, John Langdon Down termed the condition “mongolism” before it was later termed Down syndrome in honor of his discovery. Nearly a century later, geneticists Jerome Lejeune and Patricia Jacobs reported the chromosomal abnormality for the first time in humans to be secondary to a trisomy of chromosome 21…

    impacts on a patient can be severe if precautions aren’t taken immediately and often. A child/patient with Down’s Syndrome is at a high risk for developing respiratory infections, heart defects, hearing loss, eye abnormalities, and overall develop at a slower rate (Facts about Down Syndrome CDC).

It all originates with what is…

    arm of chromosome 5 in the affected person. This deletion is seemingly spontaneous in most affected individuals. “Approximately 90% of cases results from a sporadic, or randomly-occurring, de novo deletion” (6. pg. 606). This deletion may include a fraction to the entire loss of the p arm of the fifth chromosome as a whole. Taking into consideration the very spontaneous nature of this disorder, at this time the disease is not considered to be entirely hereditary, although the disease…

  • Chromosomal Inheritance

    Chromosomal inheritance relates to how a person has 2 sets of chromosomes, 46 in total, that they inherited their parents. Chromosomes carry the genes, particularly the alleles that the offspring inherit. Gregor Mendel had no understanding of chromosomes when conducting his studies. He experimented and tested peas and discovered that some genes were dominated (showed up) while others were recessive (hidden). What he didn’t know was that chromosomes contained the genes that were responsible for…

  • Down's Syndrome: Intellectual Disabilities In Children

    Down syndrome (or Down’s syndrome) is a generic chromosomal disorder which is caused by the presence of an extra chromosome 21. It is also known as “trisomy 21”. This condition leads to deficiencies in both cognitive ability and physical growth. It is typically related with physical growth delays, characteristic facial features, and minor to moderate intellectual disability. The IQ level of an adult decreases because of this. This genetic disorder, which differs in severity, sometimes causes…
