OMIM® : ⁵⁷ Radin is a rare red cell antigen discovered by Rausen et al. (1967) in 5 families with varying ethnic backgrounds. It has been shown to cause mild to moderate hemolytic disease of the newborn in some cases. The Radin antigen is determined by a polymorphism in the ERMAP gene (609017.0003) and thus is a member of the blood group Scianna (Wagner et al., 2003). Radin has alternatively been labeled Sc4 to reflect this relationship. Harvey et al. (1983) estimated the frequency of the Radin antigen among Europeans to be 0.04% to 0.66% with the highest frequencies occurring among Swedes and Danes. (111620) (Updated 05-Mar-2021)
