You're probably right.
It might be useful to flag those with a pre-disposition, some of whom might even make the changes necessary to avoid their genetic fate. But yeah they'd need lots of data. I suspect at least some it exists, could still have been done the old fashioned way, although it would get annoying for long-term with multiple daily samples.
