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]

Variant summary: RHAG c.1108G>A (p.Gly370Arg) results in a non-conservative amino acid change located in the Ammonium transporter AmtB-like domain (IPR024041) of the encoded protein sequence. Three of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 8e-06 in 250452 control chromosomes. c.1108G>A has been reported in the literature in homozygous individuals affected with Rh-Null, Regulator Type (e.g. dePaulaVendrame_2022). These data indicate that the variant is likely to be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publication has been ascertained in the context of this evaluation (PMID: 36093570). ClinVar contains an entry for this variant (Variation ID: 2244914). Based on the evidence outlined above, the variant was classified as likely pathogenic. -

The c.1108G>A (p.G370R) alteration is located in exon 8 (coding exon 8) of the RHAG gene. This alteration results from a G to A substitution at nucleotide position 1108, causing the glycine (G) at amino acid position 370 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
