Syndrome

Down Syndrome affects physical growth, facial characteristics, and intellect. Also known as Trisomy 21, it is a genetic mutation in which a person is born with an extra chromosome. These chromosomes are rod-like structures where genetic materials are stored and grouped. The nucleus of each cell in the human body contains 23 chromosomes, half, being inherited from each parent. The added chromosome changes the systematic development, affecting not only physical traits but mental as well. Common…

development can cause Down syndrome also called Downs Syndrome named from John Langdon Down, an English Physician, who wrote about it in 1866. A child born with this defect has an extra or abnormal chromosome 21.this changes the way the body and brain develops, and depends on the type of down syndrome and how may cell shave an abnormal chromosome 21. Experts believe that changes often occur before conception in the woman’s egg and less of ten in the sperm. The type of Down syndrome called…

Those who live with Down syndrome (Downs) have normal lives even if they may have a few characteristics that are different from those who do not. There are many types of Down syndrome, symptoms, diagnostic tests, and complications that characterize people who have Downs. But as shown, they are not as different to everyone else as some people may think, besides the extra 21st chromosome and a few other features. These can include physical characteristics, intellectual struggles, and a few…

just gone to the doctor and became diagnosed with Asperger’s Syndrome. At this age, you may not know exactly what this means,on the other hand, you do recognize that you’re different from the other children around you. A form of autism considered to be on the “ Higher- functioning end of the autism spectrum,” called Asperger…

that creates an extra portion or copy of the 21st chromosome. This disorder is called Down syndrome. It is the most commonly occurring chromosomal condition. People who are born with Down syndrome usually have a flat face ,Protruding tongue, Upward slanting eyes, Unusually shaped or small ears, Poor muscle tone, Broad, short hands with a single…

and children diagnosed with this syndrome have difficulty in interacting with others socially and manifest a restrictive range of interests and/or repetitive behaviors. However, unlike other forms of ASD, those affected by Asperger Syndrome do not show or have significant delays or difficulties in language or in cognitive development. Some patients even demonstrate advanced vocabulary – often and usually in a highly specialized field of interest. The Asperger syndrome is a developmental…

Turner syndrome, also known as TS and gonadal dysgenesis, is a chromosomal deficiency affecting over two million women that occur when two of the X chromosomes in a female’s DNA are either incomplete or missing entirely. It usually becomes apparent when a female is only a few years old, or even shortly following her birth. The missing genetic material of the X chromosome keeps the female body from maturing on its own. Because Turner syndrome is different for every female and an individual…

chromosome 21, this is referred to a developmental disorder known as Down’s Syndrome or Trisomy 21. An individual with Down’s have three copies of their genes instead of two, therefore disturbing the control of protein production within cells. It is so common and widespread that 1 out of every 800 to 1,000 babies are affected by Down’s Syndrome (FamilyDoctor). This means, according to the article entitled “Down Syndrome” from the University of Utah, “400,000 babies in the U.S have Down’s”. It is…

Background Turner’s syndrome is a genetic disorder that occurs in 1 in every 2,500 female births. Though it occurs in about 3% of fetuses, 99% of these fetuses are spontaneously aborted[1]. Turner’s syndrome can be defined as a combination of phenotypes with varying expressivity along with the complete or partial loss of an X sex chromosome[2]. Symptoms of Turner’s syndrome include, but aren’t limited to short stature, glucose intolerance, broad chest and widely spread nipples, amenorrhea,…

normal two copies. Trisomy 21 is known as the congenital disorder Down syndrome. This occurs when each cell has three copies of chromosome twenty one rather than having a pair. Commonly, Down syndrome is caused by nondisjunction. Nondisjunction is "an error in which homologous chromosomes or sister chromatids fail to separate normally during meiosis or mitosis" (Huether,McCance pp.42). Scientists have discovered that Down syndrome is caused by an extra chromosome, but the cause of why that…
