A CFS study on genetic risks found flawed


Senior Member
Looks like the take-home message is that if you are trying to determine whether a given SNP mutation is more common in ME/CFS patients compared to healthy people, you have to compare it to 23andMe's own database of healthy control data, rather than any other genetic reference databases.
