Genes affected
RHAG (HGNC:10006): (Rh associated glycoprotein) The protein encoded by this gene is erythrocyte-specific and is thought to be part of a membrane channel that transports ammonium and carbon dioxide across the blood cell membrane. The encoded protein appears to interact with Rh blood group antigens and Rh30 polypeptides. Defects in this gene are a cause of regulator type Rh-null hemolytic anemia (RHN), or Rh-deficiency syndrome.[provided by RefSeq, Mar 2009]

The homozygous p.Val270Ile variant in RHAG has been reported in an individual with cosanguineous parents and Rh-null syndrome (PMID: 10467273). Of note, this variant was found in cis with p.Gly280Arg in RHAG in this individual (PMID: 10467273). This variant has also been identified in >10% of South Asian chromosomes and 176 homozygotes by ExAC (http://gnomad.broadinstitute.org/). In summary, this variant meets criteria to be classified as benign for Rh-null syndrome. -
