The LW blood group-transient LW(-) case report.

Characterization of the gene encoding the human LW blood group protein in LW+ and LW- phenotypes.

The LW blood group is carried by a 42-kD glycoprotein that belongs to the family of intercellular adhesion molecules. The LW gene is organized into three exons spanning an HindIII fragment of approximately 2.65 kb. The exon/intron architecture correlates to the structural domains of the protein and resembles that of other Ig superfamily members except that the signal peptide and the first Ig-li...

The LW blood group system: a review.

The Rh blood group system is one of the most polymorphic and immunogenic systems known in humans. In the past decade, intense investigation has yielded considerable knowledge of the molecular background of this system. The genes encoding 2 distinct Rh proteins that carry C or c together with either E or e antigens, and the D antigen, have been cloned, and the molecular bases of many of the anti...

Rh and LW blood group antigens

History and nomenclature The Rh system is second only to the ABO system in importance in transfusion medicine because Rh antigens, especially D, are highly immunogenic and cause hemolytic disease of the fetus and newborn (HDFN) and hemolytic transfusion reactions (HTRs). HDFN was first described by a French midwife in 1609 in a set of twins, one of whom was hydropic and stillborn, whereas the o...

Lw Me

The LW blood group glycoprotein is homologous to intercellular adhesion molecules.

The LW blood group antigens reside on a 42-kDa erythrocyte membrane glycoprotein that was purified by immunoaffinity and partially sequenced. From this information, a specific PCR-amplified DNA fragment was used to screen a lambda gt11 human bone marrow cDNA library. Two forms of cDNA were isolated; the first encoded a single spanning transmembrane protein of 270 amino acids, including a 29-ami...
