Newly developed genetic tests make it possible to determine if individuals have the genes for diseases such as Huntington's disease. Because Marsha and Ray know that the disease runs in their families, they had their newborn daughter tested. If the genetic test reveals that the baby has the gene for Huntington's disease, what is the likely outcome?

Question

Quizplus · Accepted Answer

If the genetic test reveals that the baby has the gene for Huntington's disease, it means that she has inherited the mutated gene from one or both of her parents. This gene causes the progressive deterioration of brain cells, leading to the onset of symptoms such as loss of motor control, cognitive decline, and emotional disturbances. There is currently no cure or treatment for Huntington's disease, and individuals who have the gene are certain to develop the disease at some point in their lives. The age of onset may vary, but it usually occurs between the ages of 30 and 50. Therefore, if the baby has the gene for Huntington's disease, she will inevitably develop the disease at some point in her life.
