Heritance percentage of schizophrenia?

[fawk3s]

Hi

I can't find the exact answer anywhere. What is the heritance percentage of the disease for children or grandchildren from a male person?
So let's say "granddad" has the disease, what are the chances his grandson will inherit it?

Yes, my grandfather had it, but I am not afraid of the inheritance. I am just interested.
I would also like to know the chances for me being a carrier.

Thanks in advance,
fawk3s

I, too, have an interest in this subject...my great-grandmother very likely had it.
