Just curious, but how do you know that you are a "holder of the slow gene"?

a) personal experience, also my mom carries it. b) I had my exome sequenced in 2018, and Promethease generated a report from it that showed slow metabolizer in cyp1a2

Probably though 23andMe and the CYP450 enzyme CYP1A2.

Actually went through fullgenomes.com - they apparently don't offer exome sequencing any more but for under $1200 getting your genome sequenced is interesting.

If you ask anyone who works in genetics, though, they'll advise you never to do it. It can be bad news, but there's virtually no good news there.
