50% of all disease genes found, really?

I have been reading now many times in nature genetics that a few newly found SNPs explain about half of the attributable risk by genes while I fear that this probably mixes up different epidemiological concepts.
The population attributable risk is usually defined as the reduction in incidence that would be observed if the population were entirely unexposed. This cannot be meant as I don’t know of any genetic study examining incidence so far. Continue reading 50% of all disease genes found, really?
