Researchers have successfully located the gene and DNA sequence for
Huntington's Disease on Chromosome 4 and have created a genetic test to
determine if a person carries this gene. "The child of a person with
Huntington's has a 50% chance of inheriting the gene, which inevitably leads to
the disease... displayed 300 characters

Because the medical costs of treating
such persons in terminal illnesses are extremely high, insurance companies who
want to stay in business see this genetic test, and others like it, as an
opportunity to screen prospective clients for the probability of such diseases.
Some people feel that this information gives insurance companies unfair
advantage over those covered by medical insurance and point out that release of
genetic information to insurance companies puts a severe disadvantage on the
person who is screened, as well as violates the patients right to privacy... displayed next 300 characters
Medical conditions related to gene mutations are called genetic disorders.
There is a project currently going on called the Human Genome Project.
This international project is mapping a complete and accurate DNA sequence representing the genetic blueprint and evolutionary history of the human species...
High levels of
lactic acid have been detected in patients of Huntington's disease as a bi-
product of the brain cells working too hard. Also, up to six times above the
normal level of an important brain brain protein, bFGF (or basic fibroblast
growth factor) in areas of the brain effected by the chorea...
Typically, the abnormal movements begin at the extremities and then later progress to involve the trunk. Other symptoms exhibited by hd patients eventually include slurred speech, speech volume control issue, swallowing disorders frequently resulting in gagging and or choking, behavior problems, depression, loss of cognitive abilities, changes in personalities, and eventually develop mental deterioration leading to dementia...

souly our decision to whether or not we wanted to have a child, but he warned us
that the child could have a 50% chance of having the disease...
In an average
person, the number of repeats is between 9 and 37. But is a sufferer of HD, the
repeat count is from 37 to 86. While nobody has found a direct correlation
between the number of repeats and the age when symptoms appear, there is
evidence that people with very high numbers of repeats contract the rarer early-
onset Huntington's disease, which usually affects people under the age of 20...
