If 23&Me checked for the specific marker, then sure. But they focus on family lineage and not exactly unique mutations. Mutations are also rare, you could have it while neither of your parents do as well. So they wouldn’t be exactly incentivized to run the test I’d bet. It’d be more logical for a company who assess cancer likelihoods to be willing to run this test though.
Could one potentially look if they have the mutation from a 23&me export or something?
