Chris Hemsworth, famous for his role as the god Thor in Marvel Cinematic Universe movies, has announced he will be taking a break from acting after being told he has two copies of the APOE4 gene, increasing his risk of Alzheimer’s.
Having one copy of the APOE4 gene increases your risk for Alzheimer’s 2-3 times. Two copies increases your risk 10-15 times.
But the key here is “risk”. Having one or more copies of the gene doesn’t guarantee Chris or anyone else in a similar situation will go on to develop Alzheimer’s, the most common form of dementia.
