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]

This sequence change falls in intron 7 of the RHAG gene. It does not directly change the encoded amino acid sequence of the RHAG protein. It affects a nucleotide within the consensus splice site. This variant is present in population databases (rs200874223, gnomAD 0.009%). This variant has not been reported in the literature in individuals affected with RHAG-related conditions. ClinVar contains an entry for this variant (Variation ID: 1354370). Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant is not likely to affect RNA splicing. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
