title: A1 weak B phenotypes found in two generations of a Romanian family: A1Bx versus cis AB complex.
abstract: Three 'A1 weak B' blood groups found in two generations of a Romanian family were studied with quantitative and thermodynamic assays in order to determine if they derive from 'A1Bx' or from 'cis AB' genotypes, what cannot be achieved by the genetics.
