Do genetic diseases that don't show up until later in life get passed on more frequently?

It seems like they would. Because if a diseases that showed up earlier in life, say while you were still fertile, then there's more of a chance of you dying/becoming incapacitated and not being able to reproduce and therefore not able to pass on the disease.

Yes. Huntington's ~~~chorea~~~ disease usually starts after 30, which is a major factor in its continuing existence. You've already reproduced by the time it starts. When it starts before 20 (juvenile HD), there's much more strictly limited reproduction.
