Humans have two different Rh genes: RHD ...It’s called Rh-null blood, or much more dramatically, “golden blood.” For years, scientists believed that no one could survive with the Rh-null blood type, since it can lead to serious complications. Finding the woman in Australia, and subsequent people with what they believe is a similarly mutated gene, dispelled the myth.

Background: Rh(null) is a rare autosomal recessive disorder, and Rh(null) of the regulator type may result from mutation of the RHAG gene, which encodes RhAG glycoprotein and modulates Rh antigen expression.
