FRAGILE X SYNDROME: A Guide for Teachers of Young Children.
Awareness of Fragile X has increased, mainly because the gene that leads to the syndrome has been recently discovered. Teachers and other people working with children are generally not aware of the syndrome and its characteristics. Next to Down's syndrome, a genetic condition, Fragile X, an inherited condition, is the second most common cause of mental retardation. In fact, an estimated 1 in 1,000 people are mentally retarded because of the Fragile X gene and many more are mildly affected or are carriers. Part of the unawareness of Fragile X is because many cases are not obvious, especially girls.
The Fragile X gene is located on the X chromosome and can cause a fragile site. An individual who carries this gene may be fully affected, mildly affected or not at all. It is not yet understood what causes the extent to which an individual may be affected. Unlike other causes of mental retardation, e.g. Down syndrome, male children affected by Fragile X often experience a decline in intellectual performance over a period of the first ten years of life. The remaining males that are unaffected may pass the gene onto their female children not male children, since, only females pass the X chromosome to male babies. Many children affected with this syndrome experience speech problems and poor auditory processing.
Fragile X is among one of these disorders. ... Without this protein needed for brain function, fragile X syndrome is triggered. ... So far the most promising method of treating fragile X, this involves relieving symptoms of fragile X with current medicines. ... In order to discover if one has fragile X syndrome a few options are available. ... However, in 1992 an accurate fragile X DNA test was created. ...
This Syndrome is usually inherited from one of the parents and about 30% of cases occur when the abnormal gene arises in an egg or a sperm of an unaffected parent.3 4 In diagnosing Marfan Syndrome, X-rays, slit-lamp eye examination, skeletal examination and complete family history are used. ... It becomes wider from being stretched thus becoming more fragile. ... A person with Marfan Syndrome. ... If the Syndrome is identified at birth, close monitoring of the skeleton is necessary, especially during adolescence. ... What would one rather have: Having an abortion after amniocente...
Autism has been found in children with brain abnormalities such as congenital rubella syndrome, neurofibromatosis, and tuberous sclerosis. Autism can also be present in genetic syndromes such as fragile X syndrome and phenylketonuria. ... Doctors will often discuss their medical history, such as possibility of seizures, hearing and visual impairments along with other conditions or syndromes such as fragile X syndrome. ... A test for fragile X syndrome may be given because of its direct association with autism. ...

Factors of Mental Retardation Mental retardation is below average intelligence and abilities which are present before the age of 18. This is determined by an IQ below 70 - 75, significantly limited in two or m...
"Genetic causes include single-gene defects such as Fragile X syndrome and chromosomal disorders such as Down syndrome. Scientists in 1992 identified Fragile X syndrome as the most common inherited cause of mental retardation, responsible for up to 10 percent of cases. People with this condition inherit a defective gene that results in a weak spot on the X chromosome, a sex chromosome. ... Fragile X syndrome is more likely to cause retardation in males than females. ... Down syndrome occurs when people inherit all or part of an extra copy of a pair of chromosomes known together as chromoso...
As a Biology major, my career options are plentiful. I have always known that I wanted to help people, and I have always been interested in the medical field. I could never become a doctor or a nurse, because of my fear of blood and needles; therefore, I am seriously considering occupational thera...
One major cause of these impairments can stem from a child diagnosed with a Syndrome. "A Syndrome is identified when a certain number of features co-occur across individuals." (Pg.74) A few examples of Syndromes that can cause problems in speech sound production are Fetal Alcohol Syndrome, Down Syndrome, Velocardiofacial Syndrome, Genetic Syndromes, such as Fragile X Syndrome, and Chromosomal Syndromes, such as Turner Syndrome, Pierre Robin, Cri du chat, Klinefelter, and DiGeorge Syndrome. The effects of most of these Syndromes include Hearing Loss, Language Delay, Mental Retardation...
Although X-ray machines have been the chief mechanical tools for internal observations of the human body since Wilhelm Roentgen discovered X-rays in 1901, the development of computers made it possible for better and more accurate techniques to be applied to scan the human body. ... This method of scanning generally involves X-rays and enables scientists to view the inside of the head in a three dimensional format on a computer screen. ... Their observations lead to a hypothesis which stated that if Thrombin is released from the blood stream into the fragile cavities between brain cells, it can...
