Hereditary mutations also cause cancer, hence familial cancer syndromes.
Yes, I know, but they're not relevant to the present discussion. We're talking about Crashfrog's statement
quote:
Remember you're born with all the mutations you'll ever have - in terms of the ones you can pass on to your progeny.
I pedantically pointed out that some germ-line mutations occur after you're born. (This wasn't really relevant, since Crashfrog meant mutations that affect your phenotype, but at least it was correct.) Germ-line mutations that cause cancer, whether they're old mutations you inherit from your family or de novo mutations that occurred in forming you, are included in the set of mutations you're born with, so they've already been mentioned. Somatic mutations that cause cancer are not part of what we're talking about because you don't pass them on to your progeny.
None of this seems to have anything to do with much of anything, so I'm sorry I raised the issue.
