Fragile X Syndrome is one of the genetic disorders that are grouped in what is called trinucleotide. "DNA is made up of four chemical building blocks called nucleotides: A, C,
T, and G." (September 1, 2006. Department of Human Health and Services Center of
Disease Control and Prevention.) When the trinucleotide repeat disorders repeat, they use 3 of these nucleotides. In everyone’s DNA it repeats, but it is only "dangerous" when they repeat many times, which causes the genes to not work correctly. "A normal FMR1 gene has between about 6 and 45 CGG repeats....

- Background (576 words) The most common cause of inherited mental impairment is Fragile X Syndrome. Fragile X Syndrome is a mental retardation that affects social, learning and intellectual disabilities. It is a result of a change and mutation in a single gene, which can be pasted on to future generations. Symptoms arise when the mutated gene, FMR1, cannot produce enough of the protein, FMRP, that the body’s cells need to function. The symptoms can vary from each affected individual depending on how severe the gene mutation is.... [tags: Health, Diseases, Mental Retardation]

- There are more than ten inherited disorders within Elhers-Danlos syndrome. Ehlers-Danlos syndrome (EDS) is a “genetic defect in collagen and connective tissue synthesis and structure” (Schwartz, 2013). EDS affects the skin, joints and blood vessels in most types. In EDS the abnormality of the collagen varies dependent on the type of EDS. Six of the main types of Ehlers-Danlos syndrome include; types I and II EDS which are called the classic type, type III hypermobile EDS, type IV vascular EDS, type VI kyphoscoliosis EDS, type VII A and B arthrochalasia EDS, and type VII C dermatosparaxis EDS (Willacy, 2011)....

- Speech Analysis On December 20, 2013 at a motivational conference for women in Austin, Texas, a woman by the name of Lizzy Velasquez delivered a heartfelt speech on the power of taking the negatives in life and turning them into positives. Velasquez is one of three people in the world that suffer from a rare syndrome that renders her impossible to gain weight. She talks about how because of this syndrome she was ridiculed, bullied and tormented both as a child and as an adult and was once referred to as the “ugliest woman in the world”, but took hold of those negatives, overcame them and turned them into positive goals for herself....

- Fragile-X Associated Disorders Information and facts for families, patients and health care providers. How common is Fragile X. Fragile X syndrome is the most common inherited cause of intellectual disabilities and the most common known cause of autism. Fragile X affects 1 in 4000 males and 1 in 6000 females. About 1 in 259 women carry fragile X. About 1 in 800 men carry fragile X. Carriers do not show symptoms of Fragile X syndrome, but they may be at risk for related disorders such as Fragile X-associated Tremor/Ataxia Syndrome (FXTAS) and Primary Ovarian Insufficiency....

- There are many forms of mental retardation. Webster’s New World Dictionary defines mental retardation as “a condition, usually congenital, characterized by subnormal intelligence” (Agnes, p404). Mental retardation can be caused by a certain birth defect due to a traumatic event during the mother’s pregnancy, or mental retardation can also be inherited. The most common inherited form of mental retardation is Fragile X Syndrome. Fragile X Syndrome was identified in the year 1991. This disability affects more males than females....

Fragile X Syndrome affects does not only affect the young or the old but it will affect anyone of any age. Children who have Fragile X Syndrome can learn many different ways of communicating with others. Also there are many ways to help a Fragile X children become more socially active. There are many ways to help Fragile X Syndrome children to communicate. Fragile X Syndrome effects people of all ages from birth till death, in many different ways.... [tags: Neuroscience]

- One term that I have heard used out of context a numerous amount of times, which is very misused, is the term “retarded”. This term has been used by your average Joe and is used in terms of joking matters, or has even been used in movies as a joke. The meaning behind this term is actually nowhere near joking matters and someone who is considered in “mental retardation” conditions lives a dysfunctional life compared to your average Joe that is using this term out of its actual use. Mental retardation comes in different forms to different extents varying across different conditions.... [tags: mental retardation, mutation, health]

- Fragile X syndrome is a sex-linked chromosomal abnormality that is more common in males than in females and is also less problematic of the majority of females. The presence of an abnormality in the X chromosome causes Fragile X syndrome. It becomes constricted and often breaks. There are some different outcomes that can occur within a person with fragile X syndrome. Mental retardation, learning disability, and anxiety can all be linked to fragile X syndrome. Many behavioral and cognitive problems occur as well.... [tags: chromosomal abnormality, sex]

- The Neurobiology of Mental Retardation: Fragile X Syndrome In my previous paper, I wrote on the topic of the nature-nurture debate and the ways it related to the brain-equals-behavior dilemma. In this paper, I will continue this investigation into the link between genes and neurobiology, but I will focus in on a particular aspect of the relationship: neurological disease caused by genetic aberration. There are many well studied and well documented (thought not necessarily well understood) disorders associated with the X chromosome, and a large number of these have neurobiological roots and behavioral manifestations....

- Fragile X syndrome, a dominant X-linked disease, affects approximately 1 in 2,500 individuals and is a prevalent cause of inherited neurological disorders causing mental retardation (Kaufmann and Reiss 1999). A single mutated gene has been identified, FMR1, and defined as the cause of Fragile X. The Fragile X site is highly polymorphic in the chromosomes of Fragile X individuals and contains long CGG repeats. This CGG polymorphism has been identified as the cause of DNA instability (Kremer et al.... [tags: Biology]
