In particular this example:
- "Claiming credit for a proportion of work contributed to a group assessment item that is greater than that actually contributed;"
Academic Misconduct carries penalties. If a student is found guilty of academic misconduct, the penalties include warnings, remedial educative action, being failed in an assignment or excluded from the University for two years.
2011 Projects: Turner Syndrome | DiGeorge Syndrome | Klinefelter's Syndrome | Huntington's Disease | Fragile X Syndrome | Tetralogy of Fallot | Angelman Syndrome | Friedreich's Ataxia | Williams-Beuren Syndrome | Duchenne Muscular Dystrolphy | Cleft Palate and Lip
Duchenne Muscular Dystrophy - recessive X-linked form of muscular dystrophy, which results in muscle degeneration, difficulty walking, breathing, and death. It is caused by a mutation of the dystrophin gene at locus Xp21.
Osteogenesis Imperfecta - caused by defect in the gene that produces type 1 collagen, an important building block of bone. Most cases of OI are inherited from a parent, although some cases are the result of new genetic mutations. A person with OI has a 50% chance of passing on the gene and the disease to their children.
Congenital Adrenal Hyperplasia - refers to any of several autosomal recessive diseases resulting from mutations of genes for enzymes mediating the biochemical steps of production of cortisol from cholesterol by the adrenal glands (steroidogenesis).
DiGeorge Syndrome - congenital immunodeficiency. Di George syndrome is an inherited condition that lies at the more severe end of a spectrum of syndromes (also known as CATCH22 or 22q11.2 deletion syndrome) that occur when a part of the DNA on chromosome 22 is missing. Several different genes are lost, resulting in a collection of different features, including problems with the immune system, congenital heart defects and abnormalities of the parathyroid glands. z3332327 22:28, 7 August 2011 (EST)

Friedreich Ataxia – Is caused by defect/mutation of the gene FXN, the disorder is recessive. It is an inherited disease that causes nervous system damage and impaired muscle coordination (ataxia) through spinal cord, peripheral nerve and cerebellum degeneration.
Lesch-Nyhan Syndrome – Rare inherited disorder where there is a deficiency of the enzyme: hypoxanthine-guanine phosphoribosyl transferase (HPRT). This is caused by mutations of the HPRT gene located on the x-chromosome. This disorder is an x-linked recession disease, it causes kidney probems (building up of uric acid in all body fluids) and moderate mental retardation.
Farber's Disease – Is an inherited autosomal recessive lysosomal storage disease. The gene responsible making the enzyme ceramidase is mutated. This enzyme breaks down fatty material in the body’s cell. [not recommended to do, limited disease]
Mucopolysaccharidoses – Inherited metabolic disease where a defective or missing enzyme cause large amounts of complex sugar molecules to accumulate in harmful amounts in the bodies cells and tissues. They can’t break down these glycosaminoglycans into smaller chains. It ends up causing progressive cellular damage which affects appearance, physical abilities, organ and system functioning, and, in most cases, mental development.

Hey group 10 members! I've quickly done some research on the top 4 listed disorders. All of them had loads of info!! Let me know what you think and lets say by monday we should pick a topic?
Angelman syndrome - rare neuro-genetic disorder - characterised by severe intellectual disability, speech impediment, sleep disturbance, unstable jerky gait, seizures and usually a happy demeanour - occurs about one in 20,000 births - Severe intellectual disability and developmental delay - Profound speech impairment - Movement for balance disorder
Turner’s syndrome - affects about 1 in every 2,500 girls - usually short in height - born with only one X chromosome or they are missing part of one X chromosome - prevents the ovaries from developing properly - kidney problems, high blood pressure, heart problems, overweight, hearing difficulties, diabetes, and thyroid problems
Williams Syndrome - rare genetic disorder characterized by mild to moderate mental retardation or learning difficulties, a distinctive facial appearance, and a unique personality that combines over-friendliness and high levels of empathy with anxiety. - Common problem: cardiovascular disease caused by narrowed arteries - A random genetic mutation (deletion of a small piece of chromosome 7), rather than inheritance, most often causes the disorder - 50 percent chance of passing it on if they decide to have children
Cystic Fibrosis - Cystic fibrosis (CF) is a recessive genetic disease of the mucus and sweat glands, which affects the entire body. - affects mostly your lungs, pancreas, liver, intestines, sinuses and sex organs - makes it easy for bacteria to grow - Difficulty breathing - multitude of other symptoms, including sinus infections, poor growth, diarrhea, and infertility result from the effects of CF on other parts of the body

Hello! So my four diseases:
1. Fragile X Retardation: males mostly, the code CGG is repeated on a fragile area of the X chromosome. The more repeats, the more problems. See http://www.ncbi.nlm.nih.gov/pubmedhealth/PMH0002633/ for more details on symptoms etc.
2. Klinefelter Syndrome: extra X chromosome in males - XXY. Abnormal body proportions, infertility, less hair, big boobs, problems with their genitals (poor things). http://www.ncbi.nlm.nih.gov/pubmedhealth/PMH0001420/
3. Triple X: I think this is a trisomy and should be avoided? It is having XXX in females.
4. Thalassemia: blood disorder in which you have abnormal haemoglobin. Results lead to excessive destruction of RBC which leads to anaemia. Inherited from BOTH parents. Bone deformities in face, fatigue, growth failure, jaundice. See http://www.ncbi.nlm.nih.gov/pubmedhealth/PMH0001613/
Personally, out of my four I think either Fragile X or Thalassemia will be the most interesting. Angelman Syndrome and Duchenne Muscular Dystrophy also sound cool. I think we should avoid all ones that are really specific biochem disorders (or to that effect)- something like Mucopolysaccharidoses - because we might get bogged down in the details and have to spend ages figuring out what its actually doing.
What is everyone else's thoughts? See you tomorrow, Rhiannon.
I think we should do Duchenne Muscular Dystrophy. --Ashleigh Pontifex 11:03, 11 August 2011 (EST)
I agree ! Lisa Xiao 11:04, 11 August 2011 (EST)
Yes that sounds good, lets do it :) --Joanna Pak 11:38, 11 August 2011 (EST)
Yep, I'm all for it. I'm glad we can bags it before everyone else :D Rhiannon
