1:1,000 doesn’t sound that rare to me either.
That’s much higher odds that I’d feel comfortable with.
Our second son Douglas was born with one of the rarest genetic disorders an idiopathic disorder called CHARGE Syndrome. It is a 1 in 10,000 live births situation and so rare that there are literally only dozens per year in this country. That is a couple dozen in 4 million births in a country of 300 millions.
So the fact is that we know several local people who have a CHARGE Syndrome child in a Metro area of Cleveland/Akron/Canton of around four million. This is a significantly rarer occurrence for a live birth.
