Why do you need to do embryo pre-screening for something that’s not genetic? Or do you think it still is genetic despite also thinking you know the specific trigger in your case?

Edit: are you thinking it’s genetic, but exacerbated by weed?

Everything is at least partially genetic.

We have a friend whose sister has it and she went to genetics counselors before having kids.

They told her that because her sister has it that her kids had a 20% likelihood of developing it. Obviously 20% is way higher than normal.

Be sure you understand what this means. 20% higher chance (of a 1% baseline) is vastly different from a 20% chance.

I think its pretty clear which case is being discussed. 20% increase in chance is not something to generally worry about.

[jjallen]

This is through the grapevine. I thought they said 20% likelihood, not 20% higher likelihood. But this isn’t me and I don’t know the numbers well.

I do know that this woman chose to not use her own eggs for their child. And you would think that going from 1-1.2% would not make you do that. Perhaps there is another variable involved that I am unaware of. Her sister developed it after their parents divorce in her 30s fwiw.

That is much, much higher than I am aware of - and my mother's sister has schizophrenia so I did look this up a while ago. And the outcome so far is 0 cases in 25 nieces and nephews, all of us in our mid twenties or older.

From my understanding of the science, weed can trigger schizophrenia in the genetically predisposed. Schizophrenia can be triggered by other environmental factors, so the embryo screening makes sense to lower the risk of the child getting it as well.
