Reportedly, when James Watson and Steven Pinker had their genome sequenced, they declined to know their risk for Alzheimer’s disease. Clearly this is not an option for life extensionists and cryonicists, who are better off knowing whether they have a copy or, worse, two copies of the ApoE4 gene.
Patri Friedman, son of the libertarian economist David Friedman (who in turn is the son of the Nobel laureate Milton Friedman), recently learned that he has two copies of the ApoE4 gene when 23andMe updated their reports. Caucasian and Japanese carriers of two E4 alleles have between 10 and 30 times the risk of developing Alzheimer’s by 75 years of age, as compared to those not carrying any E4 alleles. Patri is a life extensionist, practitioner of the paleo diet, and recently made cryonics arrangements with his whole family at Alcor – and is thus far more prone to a pro-active course of action.
When he realized that there was no good central resource for people with copies of the ApoE4 gene he started a new blog called ApoE4 – The Ancestral Allele, which aims to share practical information and research for health-conscious E4 carriers. The first posts discuss some of the benefits of having the E4 gene (better episodic memory) and what kind of diet is recommended for E4 carriers. He also encourages guest posts and other co-bloggers to help run the website.
