Genes affected

RHCE (HGNC:10008): (Rh blood group CcEe antigens) The Rh blood group system is the second most clinically significant of the blood groups, second only to ABO. It is also the most polymorphic of the blood groups, with variations due to deletions, gene conversions, and missense mutations. The Rh blood group includes this gene which encodes both the RhC and RhE antigens on a single polypeptide and a second gene which encodes the RhD protein. The classification of Rh-positive and Rh-negative individuals is determined by the presence or absence of the highly immunogenic RhD protein on the surface of erythrocytes. A mutation in this gene results in amorph-type Rh-null disease. Alternative splicing of this gene results in multiple transcript variants encoding several different isoforms.

Ambry Genetics

Nov 09, 2021

The c.919G>A (p.G307R) alteration is located in exon 6 (coding exon 6) of the RHCE gene. This alteration results from a G to A substitution at nucleotide position 919, causing the glycine (G) at amino acid position 307 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
