Alternative titles and symbols : Scianna blood group;
Description : The Scianna blood group system was originally represented by 2 blood group antigens:
the high-frequency Sc1 antigen (formerly Sm) and the low-frequency Sc2 antigen (formerly
Bu-a) (Lewis et al., 1974). Other members of the Scianna blood group system include
Sc3 (Nason et al., 1980), Sc4 (Rd), and Sc5 (Star). Wagner et al. (2003) determined
that Rd was part of the Scianna system, and the Star antigen was discovered by Hue-Roye
et al. (2005).;
