Final answer:
Predictive testing for Huntington's disease (HD) has potential disadvantages including emotional distress, discrimination, and limited treatment options.
Step-by-step explanation:
Predictive testing for Huntington's disease (HD) involves identifying individuals who have a gene mutation that increases their risk of developing the disease later in life. While predictive testing can provide valuable information for individuals and their families, there are also several potential disadvantages to consider:
- Emotional Impact: Receiving a positive result can cause significant emotional distress, anxiety, and fear about the future.
- Discrimination: A positive result can result in discrimination, such as difficulty obtaining insurance coverage or employment.
- Limited Treatment Options: Currently, there is no cure for HD, so a positive result may not offer any immediate treatment options.
