Abstract
A combined study, supported by blood samples from many laboratories, allowed the recognition of three “new” antibodies, anti‐Lu5, anti‐Lu6, and anti‐Lu7. The reacting antigens all appear to have a high frequency, but are absent on all Lu(a—b—) red blood cells that have been tested. Family studies have shown that Lu6 and Lu7 are inherited characters but family studies on Lu5 have not been informative. The results suggest thatLu5, Lu6, andLu7genes operate on the same precursor material as do the usual Lutheran genes but there is no evidence to show whetherLu5, Lu6, andLu7are located on the Lutheran chromosome.A new Lutheran phenotype, Lu(w), displays weak Lutheran antigens.
