Test results have shown high levels of sodium and chloride in her sweat. Patient A has Cystic Fibrosis‚ which is shown by her respiratory and digestive system symptoms. Cystic Fibrosis is a genetic mutation that mutates the cystic fibrosis transmembrane conductance regulator protein(CFTR). When CFTR is working properly‚ it allows chloride to leave the cell

Huntington’s disease (HD) is an autosomal dominant neurodegenerative disease for which there are currently no treatments that slow or halt its progression(1) The cardinal early features of the disease are movement disorders‚ including chorea and incoordination‚ and later on‚ dystonia‚rigidity‚ and bradykinesia become more prominent.Patients die usually between 15 and 25 years after development of the first symptoms.(2‚3‚4) Brains from patients with HD show neuronal degeneration‚most prominently in

Is anti-social behaviour a result of genetic inheritance or your environment and upbringing? The debate of the cause of anti-social behaviour has been ongoing for many years between scientist’s‚ professionals and the general public. Experts disagree over whether genetics‚ environment or home life plays the greater role in anti-social behaviour. The general opinion over all of why people turn to violence and anti-social behaviour focuses on family breakdown‚ drug and alcohol abuse‚ poverty‚ unemployment

Huntington’s disease is the degeneration‚ or breakdown‚ of neurons within the structures of the brain. The structures affected are responsible for thought‚ perception‚ emotions‚ and memory. The basal ganglia‚ which controls movement and coordination‚ is also affected by the disease. Huntington’s disease is usually developed between the ages of 30 and 50‚ but can still develop earlier or later depending on the person. Juvenile Huntington’s disease is when it is developed in people under 20 years

Huntington’s disease Anna Richards 4th period 12/7/16 Page Break In 1872‚ the American physician George Huntington wrote about an illness that he called "an heirloom from generations away back in the dim past." One of its earliest names was chorea. Until recently‚ scientists understood very little about HD and could only watch as the disease continued to pass from generation to generation. Families saw the disease destroy their loved ones’ ability to feel‚ think‚ and

Since science developed and genetics became known‚ scientists discovered that HD is inherited from one generation to another which have put the scientists with a big challenge to find cure for such disease. In addition‚ this paper provides information about causes‚ symptoms‚ inheritance‚ treatments & a test for Huntington’s disease. My aim from

In 1872‚ George Huntington wrote about a disease that he and his family was suffering from. Symptoms included slurred speech‚ involuntary or slowed movement‚ and compulsive emotions and feelings. Today‚ it is known that this disease is a genetic disease affecting the brain‚ caused by the mutation of chromosome number 4‚ in which the codon CAG repeats over 40 times‚ contrary to the normal 10 to 26 times. Though it is unknown as to why this repetition causes such effect on the brain‚ scientists have
