title: Blood group antigen deficiencies associated with abnormal red cell shape.
abstract: Rare individuals are known with erythrocytes which show an inherited deficiency of certain blood group antigens and also have abnormal red cell shape. Studies of these cells can give an insight into the functional role of blood group active components in maintaining the shape and membrane properties of the normal erythrocyte. The biochemical characterisation of the red cell membrane alterations occurring in two such rare erythrocyte phenotypes--the Leach phenotype and the Rhnull phenotype are reviewed here.
