Did a genetic mutation lead to a woman being convicted of murdering her four children?

4. Given the totality of what you explained, I'd be quite a bit more amenable to the idea that it was

just a genetically-based occurrence ... if 1 or 2 or 3 of 4 her kids had died very young of similar causes, vs 4/4 of them.

An ex-girlfriend of mine just passed of Huntington's a couple weeks ago, at 50. Her mom and 2 older brothers had passed of the same genetic defect before her, clearly mom was the carrier, as dad is fine. But her other sibling, a sister, is unaffected.

3 of 4 seems to me like the limit for something like this before I'm not thinking to myself ... wow, that's some very bad luck, to the point where I wonder about 'other reasons'.

It's surely possible, akin to flipping heads 4 times in a row. But strikes me as pretty unlikely is all.
