Researchers have identified a particular gene defect (PHOX2B) associated with congenital central hypoventilation syndrome.

I spoke to Rush Hospital in Chicago. They told me to draw blood normally, send it regular mail ... with a check for $670, or money order.

They are the only, only lab I found that does this test. I called several places on the internet, places doctors suggested and so on.

Anyone know of a "better" place?
