This is anecdotal, but relative to the US and Russia, in Spain you see far more twins and far more kids with Down's Syndrome. Both of those cases are made more common by parents having kids at a later age. I don't know that those would pass on any mutations permanently, though, to future generations. For obvious reasons Down's Syndrome patients rarely (ever?) reproduce, and as far as I know twins aren't any likelier to bear twins themselves.
