Studies of 91 individuals in three families allowed a genetic-linkage analysis of the gene governing the production of the low-incidence red cell antigen Wra and provided evidence that Wra is not a member of the Scianna, Landsteiner-Wiener, Chido/Rodgers, or XK blood group systems, and that the "WR" locus is excluded from autosomal sites or regions 1p34-p22.1, 1p21-q23, 1q32, 2p25, 3q21, 4q28-q32, 6p24-q12, 9q34.1-q34.2, 13q14.1-q14.2, 14q24.3-q32.1, 14q32.33, 16p13, 16q22.1, and 21q21-q22.1. "WR" is also excluded from within specified genetic distances of chromosomes 8 (GPT), 18 (JK), 19 (C3), 20 (ADA), and 22 (P1) loci, which brings its exclusion to approximately 10 percent (320cM) of the total genetic map of the genome. The possibility that "WR" is pseudoautosomal is deemed to be highly unlikely.

UI MeSH Term Description Entries
D007519 Isoantigens Antigens that exist in alternative (allelic) forms in a single species. When an isoantigen is encountered by species members who lack it, an immune response is induced. Typical isoantigens are the BLOOD GROUP ANTIGENS. Alloantigens,Alloantigen,Isoantigen
D008126 Lod Score The total relative probability, expressed on a logarithmic scale, that a linkage relationship exists among selected loci. Lod is an acronym for "logarithmic odds." Lod Scores,Score, Lod,Scores, Lod
D008297 Male Males
D011995 Recombination, Genetic Production of new arrangements of DNA by various mechanisms such as assortment and segregation, CROSSING OVER; GENE CONVERSION; GENETIC TRANSFORMATION; GENETIC CONJUGATION; GENETIC TRANSDUCTION; or mixed infection of viruses.

D001789 Blood Group Antigens Sets of cell surface antigens located on BLOOD CELLS. They are usually membrane GLYCOPROTEINS or GLYCOLIPIDS that are antigenically distinguished by their carbohydrate moieties.
