Molecular basis of the JAHK (RH53) antigen

BACKGROUND: The JAHK antigen was first described in 1995 as a low‐frequency red blood cell antigen. Family studies confirmed the association of the antigen with the rare rG phenotype of the Rh blood group system, which is associated with weak expression of C and e, but normal G expression. JAHK was allocated the Rh number RH53. The serologic findings indicated the location of the antigen on the RhCE protein, although the molecular basis for JAHK has not been known.
