Thank you for this. I did read that abstract and I also saw something here as well in a different thread - "Here's some possible good news:
The original 2004 study that suggested an increased risk was done with only 148 people, all of whom came from a referral center for AD in Calabria, Italy. We don't know if those 148 people happen to be all DNA relatives or otherwise had common environmental or lifestyle risk factors. Finding that people who have Alzheimer's carry a particular SNP is much less conclusive proof of its risk association than a population-wide genomic analysis.".
I just wonder why sites include this snp when it is based on a single study of just 148 people. It is very scary to see such a thing. I do feel a greater sense of assurance and appreciate the help here. Thank you for your time.
