Rhnull.

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. This study described the molecular genetic analysis of a Chinese Rh(null) family and identified a novel mutation in the RHAG gene.
