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 RHAG p.Leu383Ile variant was not identified in the literature nor was it identified in ClinVar. The variant was identified in dbSNP (ID: rs141051794) and in control databases in 85 of 282380 chromosomes at a frequency of 0.000301 (Genome Aggregation Database March 6, 2019, v2.1.1). The variant was observed in the following populations: European (non-Finnish) in 77 of 128868 chromosomes (freq: 0.000598), European (Finnish) in 5 of 25096 chromosomes (freq: 0.000199), Other in 1 of 7204 chromosomes (freq: 0.000139) and African in 2 of 24960 chromosomes (freq: 0.00008), but was not observed in the Latino, Ashkenazi Jewish, East Asian, or South Asian populations. The p.Leu383 residue is conserved in mammals and computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) provide inconsistent predictions regarding the impact to the protein; this information is not very predictive of pathogenicity. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) do not predict a difference in splicing. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance. -

The c.1147C>A (p.L383I) alteration is located in exon 9 (coding exon 9) of the RHAG gene. This alteration results from a C to A substitution at nucleotide position 1147, causing the leucine (L) at amino acid position 383 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
