Biochemical, serological and family studies in individuals with Cis AB phenotypes.
Pedigree studies and serological characterization of three cis AB families are presented. Serums of these persons exhibit strongly reduced activities of A gene-specified alpha-acetylgalactosaminyltransferase and only trace activities of B gene-dependent alpha-galactosyltransferase.
