APOE4 Gene Testing: Understanding Genetic Alzheimer’s Risk
What is the APOE4 Gene?
The APOE4 genetic variant Chris Hemsworth carries is the strongest known genetic risk factor for late-onset Alzheimer’s disease:
APOE4 gene statistics:
- 25% of population carries one APOE4 copy
- 2-3% of people carry two copies (like Hemsworth)
- Two copies increase risk by 8-15 times
- Not a guarantee of developing Alzheimer’s
- Other factors influence disease development
Genetic Testing for Alzheimer’s Disease
Alzheimer’s genetic testing options include:
- Direct-to-consumer tests (23andMe, ApoE genotyping)
- Clinical genetic counseling through National Society of Genetic Counselors
- Comprehensive risk assessment
- Family history analysis
