Rapid Review Pathology Fragile X syndrome is associated with the expansion of the CGG trinucleotide repeat affecting the Fragile X mental retardation 1 (FMR1) gene on the X chromosome, resulting in a failure to express the fragile X mental retardation protein (FMRP), which is required for normal neural development.

Fragile X Syndrome ‘Fragile X syndrome’ is also known as Fragile X. It is the most common genetic form of mental retardation. It occurs due to changes in a gene which is passed on from one generation to the other. It can affect people belonging to all income levels and ethnic groups.

Turner syndrome Turner syndrome results when one normal X chromosome is present in a female's cells and the other sex chromosome is missing or structurally altered. The missing genetic material affects development before and after birth, leading to short stature, ovarian malfunction, and the other features of Turner syndrome.

Fragile X-associated Primary Ovarian Insufficiency (FXPOI) Women who carry a Fragile X premutation are at increased risk to develop Fragile X-associated primary ovarian insufficiency (FXPOI) and Fragile X-associated tremor/ataxia syndrome (FXTAS). In the largest US study to date (>119,000 women), the overall carrier frequency of Fragile X among US females was found to be 1.3%.

Fragile X Prevalence These statistics are important because both men and women are at risk for having symptoms linked to Fragile X-associated Disorders. 1  Women with a premutation reported their last menstrual cycle at an earlier age than women without a premutation (48 vs. 51 years).

Guillain-Barre Syndrome Guillain-Barre syndrome is a rare disorder that causes your immune system to attack your peripheral nervous system (PNS). The PNS nerves connect your brain and spinal cord with the rest of your body. Damage to these nerves makes it hard for them to transmit signals. As a result, your muscles have trouble responding to your brain.

Chapter 5 Genetic Disorders The disease is a life-long condition. Only some people with fragile X syndrome are able to live independently. According to the Genetics Home Reference (GHR), fragile X syndrome is found in about one in every 4,000 males and about one in every 8,000 females. (GHR) Males usually have more severe symptoms than females.

Why do Chinese people in a group talk to each other in their native language, even though they know that others will not be able to understand the conversation? it's because they don't have to spend a minute grasping for the English equivalent of the thought they are trying to express, so their conversation will be faster, more accurate, and more readily understood. Nobody will have to suddenly give an ESL lesson to make sure all involved got what the speaker meant.

- 1 Fragile X syndrome (also called Fragile X) is the most common inherited form of mental problems (mental retardation).  Fragile X syndrome is caused by changes in a single X chromosome (FMR1).

Treacher Collins syndrome Treacher Collins syndrome is a condition that affects the development of bones and other tissues of the face. The signs and symptoms of this disorder vary greatly, ranging from almost unnoticeable to severe. Most affected individuals have underdeveloped facial bones, particularly the cheek bones, and a very small jaw and chin (micrognathia).

How is the body affected? Connective tissue holds the body together and plays a role in its growth and development. Because connective tissue is found throughout the body, Marfan syndrome and related disorders can affect many parts of the body, including the heart and blood vessels, bones and joints, eyes, skin, and lungs. Below is a short summary of Marfan syndrome features.

What Causes Fragile X Syndrome? Fragile X is Inherited. A mother who carries Fragile X has a 50% chance of passing the mutated gene to each of her children. Her children will either be carriers or they will be have Fragile X syndrome. Carrier men will pass the premutation to all their daughters but none of their sons.

What effect does extreme cold have on the human body? The hypothalamus’s mission is to keep the core warm at all costs – sacrificing the extremities if need be. That’s why we feel pins and needles in our fingers and toes in extreme cold – the body is keeping its warm blood close to the centre, constricting blood supply in the outer regions such as the end of our limbs. In extreme cold, and especially if bare skin is open to the elements, this effect can end in frostbite. Blood flow is reduced, and the lack of warm blood can lead to tissue freezing and rupturing. So how do other warm-blooded animals living in such climes cope when we can’t? Polar animals are either covered in winter coats of fur – which traps warm air close to the body – or else large quantities of fat, sometimes inches thick. Fat does not transfer heat very well, so it keeps it inside the body. Humans, with naked skin and relatively little fat, just aren’t built for these environments. But we have learned to mimic these qualities. Scientists in Antarctic stations, for instance, dress in layers upon layers, which traps warm air close to the body like fur does. The other problem with the kind of weather currently affecting the US is that it can create problems with some of the things mankind relies on. Intense cold can bring down power lines due to the weight of ice, cutting power ...

Fragile X Syndrome Mutations in the FMR1 gene are associated with two other conditions in addition to the fragile X syndrome (FXTAS and POI) and these conditions have been termed FMR1-Related Disorders. (See the Related Disorders section of this report for brief summaries of the other disorders.).

- Serotonin syndrome is a potentially serious drug interaction that occurs when too much serotonin builds up in your body. Serotonin is a chemical normally produced by the nerve cells and helps regulate digestion, blood flow, body temperature, and breathing.

Selective PDE4D inhibitor shows potential to treat Fragile X autism spectrum disorder Fragile X syndrome is a genetic condition that results from the silencing of the X-linked, fragile X mental retardation-1 (FMR1) gene. FXS patients display a range of behavior and other symptoms, including seizures, sleep disorders, anxiety, irritability, hyperactivity, autism, mild-to-severe cognitive impairment and intellectual disability.

hypothyroidism The thyroid produces hormones that influence every organ, tissue, and cell in the body. Thyroid hormones also control heart rate, body weight, body temperature, energy level, muscle strength and menstrual regularity. When the thyroid becomes faulty or malfunctions, metabolic disorders occur.

Researchers identify key brain systems affected by fragile X syndrome Researchers identify key brain systems affected by fragile X syndrome. Researchers at the Stanford University School of Medicine have identified several large-scale neural systems in the brain that appear to be impaired by fragile X syndrome, the most common form of inherited intellectual disability.

How is Fragile X inherited? Grouped into 23 pairs, we get one set from our mother and the other from our father. One of these pairs of chromosomes determines if a person is male or female: Males (XY) get the X chromosome from the mother and the Y chromosome from the father. Females (XX) inherit one X chromosome from each parent. The Fragile X premutation can be passed silently down through generations in a family before a child is affected by the syndrome.

- Fragile X syndrome is an inherited genetic disease that causes intellectual and developmental disabilities. Inherited means that the disease is passed down from parents to children through their genes. Fragile X syndrome is the most common hereditary source of mental disability in boys. People with fragile X syndrome usually experience a range of developmental and learning problems. The disease is a life-long condition.

- Fragile X syndrome (FXS). FXS is the most common known cause of an inherited intellectual disability worldwide. FXS is a genetic condition caused by a mutation (a change in the DNA structure) in the X chromosome. People born with Fragile X syndrome may experience learning and behavioural challenges.
