Question Answered step-by-step Question 2 background: Using GD when Huntington’s Disease runs in… Question 2 background: Using GD when Huntington’s Disease runs in the familyHuntington’s disease (HD) is a genetic disorder in which nerve cells in certain parts of the brain waste away. It is caused by amutation in the Huntingtin gene. Most people affected by this disease develop symptoms in their 30s or 40s and die about 15-20years later. As the disease is passed down from one generation to the next, symptoms develop at younger and younger ages.There is currently no cure for HD. HD is a devastating disease. Symptoms include behavioral disturbances, hallucinations,irritability, paranoia, psychosis and loss of motor control. Abnormal and unusual movements include grimaces and wild jerking ofthe arms, legs, face as well as other body parts. Affected individuals also suffer from personality changes and dementia,including disorientation, confusion and loss of judgment and memoryIf one of your parents has HD, you have a 50% chance of inheriting the mutation in the Huntingtin gene. If you inherit thismutation, you will develop the disease at some point in your life, and each of your children will have a 50% chance of inheriting itfrom you. If you do not inherit this mutation, you will not develop HD and will not pass it on to your children. It is possible forpeople who know they carry a mutation in the Huntingtin gene to avoid passing it to their children. By using invitrofertilization (IVF),in which eggs are fertilized with sperm outside the womb, it is possible to test embryos for genetic mutations prior to transfer tothe uterus. This strategy enables parents to select only embryos that are free from the mutation in the Huntingtin gene.Question 2: If you knew that you carried a mutation in the Huntingtin gene but wanted to have children, what are your options? What do you think you would do in this situation? Science Chemistry CHEM 299 Share QuestionEmailCopy link Comments (0)
