The Red Cell Antigen JAL in the Swiss Population: Family Studies Showing That JAL Is an Rh Antigen (RH48)

Abstract
The JAL antigen was found to have an overall frequency of 0.004% in the Swiss population and 0.06% in French‐speaking Swiss. Family studies of 5 JAL+ individuals have shown that the JAL antigen is not part of the ABO, MNSs, Fy, Jk and Co blood group systems, or the Se system, nor is it X‐ or Y‐linked. JAL is encoded by the RH locus or by a very closely linked locus. The number RH48 (4.48) has been assigned for JAL by the International Society of Blood Transfusion Working Party on Terminology for Red Cell Surface Antigens.
