Fragile X Syndrome
Frequency of Fragile X
Fragile X Syndrome can occur in all types of ethnic groups. However, it differs in the prominence in different genders. Because it is a sex-linked dominant gene, more males will be affected by this disorder. An estimated 1 in 4000 males are affected and 1 in 6000 females. One in 100/250 women are carriers for the gene. These female carriers often suffer from infertility and early menopause.

Fragile X Syndrome is one of the most common forms of inherited mental retardation.
Fragile X Syndrome is a sex-linked dominant disorder caused by a change or mutation in the DNA on an X-chromosome. This disorder is a tri-nucleotide repeat disorder. This means that the X chromosome carrying this trait has an overabundance of DNA, specifically CGG repeat. Typically, CGG is repeated 5 to 40 times. However in Fragile X individuals, it can be repeated over 200 times. This amount of CGG can stop the FMR1 gene. The FMR1 gene prevents mental retardation, therefore if the gene is stopped, Fragile X can occur. Family members who have no sign of Fragile X syndrome can pass it on.
This pedigree shows the line of inheritance of the disorder, Fragile X. Here, it is clear that more males are affected in comparison to females.

Physical: large or protruding ears, soft skin, flexible joints, low muscle tone, large testicles, long face.
Behavioral: speech and language delay, motor delay, hand-flapping/biting, and gaze aversion.
In adults: learning new skills, maintaining friendship.
Issues in females: mathematics, shyness, poor communication skills, mood swings, anxiety, ovarian insufficiency, and early menopause.
Family history: learning disability, females with infertility or premature menopause, adults with late onset psychiatric changes.

Tourette's Syndrome

...Many people wonder what Tourette’s syndrome is exactly. Although I sure people have seen from movies, would think someone with Tourette’s would curse a lot loudly, or say inappropriate expressions, but that is lease likely to occur. Tourette’s syndrome is one of many disorders in a human. It is a neurological disorder that makes people lose control of their body, twitch uncontrollably, and shout out unusual words, also may cause blinking repeatedly, these are known as tics. This disorder is known to be hereditary, but also may just so happen due to stress and what not. It is known when having Tourette’s syndrome; you may also have another sort of disorder. Sadly, there is no cure for this mysterious disorder, but with professional help and medication, the tics can be less severe. But hopefully soon enough, maybe later on in the future there will be a cure for this disorder. If having tics for over a year a doctor would say you have a chronic tic disorder, in most cases its part of Tourette’s, which was first determined, in 1825 by a doctor named Georges Gilles de la Tourette, a French neurologist. In 1885, he proclaimed a cause of the syndrome on a few patients. Most of his patients were young men. It was known that having this disorder was very rare. He found that the disorder was running in families. While finding ways to describe the disorder, it has been named after him. With having this disorder it is mostly found during childhood, usually within the ages of 7 and 10......

Aase Syndrome

...Aase Syndrome is a rare genetic disease that causes anemia and poor development of bone marrow. There’s less than two dozen cases reported. One main trait that stands out from others to diagnose this disease is the triphalangeal thumb. Carriers of Aase syndrome are diagnosed during their baby years. Doctors perform a blood transfusion the first year of life, and continue treatment by using steroids. There’s another anemia disease called Blackfan-Diamond syndrome that has similar symptoms such as the abnormalities of the thumb, which arises questions if these diseases are contiguous gene syndrome or even identical conditions. Even through major procedures that may be needed, the end results seem good. Aase syndrome is a rare genetic disorder that can be diagnosed by a triphalangeal thumb or a certain anemia that causes poor development of the bone marrow, which is where blood cells are formed. Both parents must have it to pass the gene down, but it's not for sure it will be inherited. There's been less than two-dozen cases reported in the medical literature. A lot of symptoms are related to the joints or are skeletal deformities such as pale skin, delayed closure of soft spots, triple jointed thumbs, narrow sloped shoulders, droopy eyelids, deformed ears, cleft palate. Carriers with Aase disease may have difficulty picking objects up and being able to grasp on to them,...

Fragile X

...205 Fragile X Syndrome The most common form of inherited mental retardation today is none other than Fragile X Syndrome. Fragile X is a chromosomal disorder caused by a mutation of the FMR1 on the X chromosome that some individuals, mostly males, are born with rather than develop later on and it is seen all around the world. A couple of major contributors to the Fragile X syndrome discovery are J. Purdon Martin and Julia Bell. In 1943, they studied a family in which numerous males had mental retardation. By inferring that it was genetic, they were able to link this mental retardation to an X-linked inheritance. In 1969 Herbert Lubs first discovered Fragile X syndrome under a microscope. He revealed that one of the arms on the X chromosome appeared broken hence the name Fragile X. The FMR1 gene provides guidelines that make a protein named fragile X mental retardation 1 (FMRP). The symptoms seen are caused because the gene cannot produce enough FMR1 protein that is needed in cells of the body and especially in the brain for normal development. Fragile X is somewhat preventable due to prenatal genetic counseling now that the disease is more understood. Meaning, a woman can get tested to see if she is a carrier of Fragile X. From there she can decide if she wants to have children and risk passing down this disease to them. Individuals affected by Fragile X syndrome have difficulty with sequential processing, learning disabilities, and many other things. Fragile X Syndrome is......

Rett Syndrome

...Rett Syndrome Joseph Lee 4th Period Rett Syndrome is a disorder which affects the nervous system and is found almost exclusively in girls. One in 10,000-20,000 newborn babies are born with Rett Syndrome, making this disorder very rare. Rett Syndrome is often described as autism, cerebral palsy, Parkinson’s, epilepsy, and various anxiety disorders wrapped into one. In this paper, I will discuss what exactly Rett Syndrome is, who discovered it, how he discovered it, what its causes are, what the symptoms are, the disorder’s course, and possible treatments for the disorder. Said Dr. Rett at a conference regarding the disorder which bears his name: These three words summarize best our task: To live, to love, and to learn. We are aware of the fact that many mysteries of this syndrome still remain undisclosed, and therefore, for the time being, we have no option but to live with it. However, the children with their very special ways give us enough impulse to share their lives. It is a further mystery of this syndrome that the affected children render it easy for us to love them. A dominating factor in the care of such children is that they understand us and we understand them. Their appearance and the sparkle in their eyes make it easy to love them. Daily care for them and working with them gives us grownups strength, enabling us to learn the special treatment required, thus furthering our own development. To...

How Fragile Life Is

...Good morning everyone. Today I am going to share with you a story of how fragile life can be. It is the story of Formula 1 driver, Michael Schumacher. Michael Schumacher is known as Formula 1’s greatest ever driver, having claimed 7 world championships. Schumacher was born in Germany on Jan 3rd 1969. He started racing karts at the age of 4, and at 18 he won the German and European Kart championship. When he was 21 he won his first major single-seater title, clenching the German Formula 3 crown. In 1991 he made his Formula 1 debut, for Jordan in Belgium. In the year 2000, Michael won the world championship for Ferrari for the first time since 1971. From his very first race in Formula 1, he was bold, confident, and passionate about being behind the wheel. His love for racing and speed never got in the way of safety, as Michael knew the dangers of racing better than most. He was accomplished at knowing how to deal with every twist and turn in the fastest way possible. After 308 races, going around international F1 tracks for practice and races (approximately 10 000 in his career), at some points being over speeds of 300 km/h, experiencing G forces as high as 5.5 G’s, this German racing driver certainly knows how to handle speed, has highly tuned reflexes and a great sense of anticipation! His body was conditioned for extra stamina and handling tight space conditions and extreme heat. His strength and endurance allowed him to handle all of the......

Ehlers Danlos Syndrome

...Ehlers Danlos Syndrome Ehlers-Danlos syndrome (EDS) is a rare genetic inherited syndrome. Ehlers-Danlos syndrome affects the connective tissues, which provide support to the skin, bones, blood vessels, and other organs of the body. There are six types of EDS hyper mobility, classical, vascular, kyphoscoliosis, arthrochalasia, and dermatosparaxis. Some types are so severe that people can’t participate in any sport activities or any physical activity. The two major types of EDS are Classical EDS and Hyper mobile EDS. These two types make up 90% of all EDS cases. Eduard Ehlers, a Danish physician, and Henri-Alexandre Danlos, a French physician, first described EDS. I chose Ehlers Danlos syndrome because I have it and wanted to learn a little bit more about it. I also wanted to see if there are any nutritional things I can do to improve my condition. I was diagnosed with EDS when I was 15. I kept dislocating my shoulder and was in a lot of pain, so I went and got an MRI. It turned out I didn’t have a tear, the doctor sent me to get tests done to see if I had EDS. I went through the physical tests and blood samples and found out I had Hyper mobility EDS. The symptoms of hyper mobility EDS are: chronic dislocations, easily bruised, stretchy skin, joint pain. Another symptom of this type of EDS is subject to frequent injury, week bones and chronic fractures. After hearing all of this it made sense since I have all of those symptoms. Ehlers Danlos Syndrome is a new disease......

Fragile X

...What is fragile X syndrome? Fragile X syndrome is a genetic condition that causes a range of developmental problems including learning disabilities and cognitive impairment. Usually, males are more severely affected by this disorder than females. Affected individuals usually have delayed development of speech and language by age 2. Most males with fragile X syndrome have mild to moderate intellectual disability, while about one-third of affected females are intellectually disabled. Children with fragile X syndrome may also have anxiety and hyperactive behavior such as fidgeting or impulsive actions. They may have attention deficit disorder (ADD), which includes an impaired ability to maintain attention and difficulty focusing on specific tasks. About one-third of individuals with fragile X syndrome have features of autism spectrum disorders that affect communication and social interaction. Seizures occur in about 15 percent of males and about 5 percent of females with fragile X syndrome. Most males and about half of females with fragile X syndrome have characteristic physical features that become more apparent with age. These features include a long and narrow face, large ears, a prominent jaw and forehead, unusually flexible fingers, flat feet, and in males, enlarged testicles (macroorchidism) after puberty. How common is fragile X syndrome? Fragile X syndrome occurs in approximately 1 in 4,000 males and 1 in 8,000 females. What genes are related to fragile X......

Down Syndrome

...Down syndrome Development Psychology Down syndrome Love a four letter word that many will take and throw around as though the word is a ball to be toyed with. One seeks to have someone say “I love you” no matter what their ability is as being mentally challenged or not. A parent does not love his or her child any less if he or she suffers an illness such as that of Down syndrome (DS). In order to completely understand how the love of a mother and father can be given to a child with such a disability, the individual needs to gain an understanding of what Down syndrome is. The reader of this paper will learn how Down syndrome got the name, what Down syndrome is, the case for this disorder, the facts that are known of Down syndrome. The methods used to test and find DS before the birth of a child. Statistical facts, the medical conditions which are present, how parents and teachers work with those born with DS. How the eating habits, sexuality habits of males and females with Down syndrome are viewed. The length of the life expectancy for someone who is challenged with DS compared to someone that is not mentally challenged. The last thing that I will cover within this paper is that of foundations that have been created to conduct research and treatment for those with Down syndrome and to answer the question that many may have as to there being a cure for Down syndrome.

Metabolic Syndrome and Cardiovascular Disease

...Metabolic Syndrome and Cardiovascular Disease According to ‘Metabolic syndrome’ (also called dysmetabolic syndrome or syndrome X) is defined as ‘a cluster of conditions — increased blood pressure, a high blood sugar level, excess body fat around the waist and abnormal cholesterol levels — that occur together, increasing your risk of heart disease, stroke and diabetes.1’ Metabolic syndrome is becoming increasingly common and is now recognised as a major causal factor in cardiovascular disease. Cardiovascular diseases (CVD’s) are any illnesses that involve the blood vessels (veins, arteries and capillaries) or the heart, or both - diseases that affect the cardiovascular system.2 Cardiovascular diseases are said to be the number 1 cause of death globally: more people die annually from CVDs than from any other cause.3 Cardiovascular diseases include blood vessel diseases, such as coronary artery disease; heart rhythm problems (arrhythmias); and heart defects one may be born with (congenital heart defects), among others.4 Most cardiovascular diseases can be prevented by addressing behavioural risk factors such as tobacco use, unhealthy diet and obesity, physical inactivity and harmful use of alcohol using population-wide strategies.3 As mentioned in the definition, hypertension and hyperglycaemia are 2 main features of metabolic syndrome that can lead to cardiovascular disease. Hypertension, or high blood pressure, is a blood pressure reading of 140/90 or......

Survivor Syndrome

The barrier may either be overt (outward, or physical) or covert (inward, or mental-socio-psychological). Overt acts might include strikes, work slowdowns, grievances, or lawsuits. Covert acts would include sabotage, secret withholding of output and stealing of organisational property. A smooth progression of the need-driven incentive motivational cycle and fulfilment of one’s expectations do not always occur in reality. There are some difficulties and barriers that do not let a person achieve his goals and so they lead to frustration. The frustration model can be useful in the analysis of not only behaviour in general but also specific aspects of on-the-job behaviour as illustrated by. 12e in the model below F.
