Step by step
Solved in 2 steps
- Describe the effect of aging?Huntington chorea is an inherited disorder, with children of a parent with the disorder having a 50% chance of developing the disease. An individual with the disease usually does not manifest symptoms until he or she is between 30 and 45 years of age. The disease then progresses to death over the next 10 to 15 years. If a child of an affected parent has not developed symptoms by the age of 45, it is not likely that the symptoms will ever develop. Discuss your thinking process when deciding whether you would or would not choose to have the testing to know if you will develop Huntington chorea.define aging, and describe the mechanisms thought to cause it?
