Getting SZA/SZ from older parents?

Is it possible that genetically even though my parents don’t have it nor my grandparents (that I know of only 1 grandparent was alive when I was born) can pass down the gene from old age. I know it is possible for a child to be born with downs or autism with parents of that age but what about SZ. My parents had me at 44 (mother) and 46 (father) which for the mother is older to have a child. It’s very easy to see environmentally how it was triggered because of school but I just can’t find any links genetically unless my parents are lying or also unaware of any illness in the family.

Found this. Any thoughts?

There is a slight increase in risk - a few percent increase in risk with an older father. See here:
