Abstract:An antibody, named anti-Lu 11, has been found that reacts with a highfrequency red-cell antigen related to the Lutheran blood group. The reacting antigen is absent from red cells that are Lu(a-b -) and is weakly active on the red cells of newborn infants.
“…Because all the other antigens were associated with single‐point mutations or small deletions, there is a possibility that LU11 was not a part of Lutheran system. Although there are at least three examples of LU:−11 individuals, there is no evidence that LU11 is inherited 18,19 …”

“…Lu11: Gralnick and colleagues 33 described the first example of anti-Lu11. Anti-Lu11 was present in the serum of a Caucasian woman who had four children and a history of transfusion.…”
At first sight, the Lutheran system would seem to have little interest to blood bankers. Lutheran antibodies are rarely, if ever, clinically relevant, although their identification has the potential to be enormously time-consuming. However, other complexities of this system are proving to be extraordinarily intricate. Genetically, the system appears to be composed of at least three closely linked loci, each with two alleles and, so far, 20 antigens, which have laid claim to at least an honorary affiliation.Two antigens, Lu10 and Lu15, have become obsolete.Three different interpretations of the genetic events leading to the Lu null phenotypes have been needed to accommodate the hereditary observations. The biochemistry of the cell membrane structures on which Lutheran antigenic activity resides is starting to be unravelled. Information about Lutheran has been accumulating for 50 years.This review will summarize what is known to date.
“…The three family members who are Lu(a-b -) are also Lu:-3, -4, -5, -6, -7, -8, -9, -11, -12, -13, while the remaining members are Lu: 3,4,5,6,7,8,11,12,13. None of the family possesses the uncommon antigen Lu9.…”
A family is described in which three members are of the recessive Lu(a-b-)
type. These individuals also lack the high-frequency Lutheran-related antigens Lu4, Lu5,
Lu6, Lu7, Lu8, Lu11, Lu12 and Lu13. There is no evidence that lack of Lutheran antigens
compromises red-cell membrane integrity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
