Inherited 'mosaicism' within the ABO blood group system
Journal of Immunogenetics
|August 1, 1978
Abstract:
A family with examples of the rare condition known as 'inherited mosaicism affecting the ABO blood groups' has been studied. In this family there were five examples of Bmos:O mosaicism. Blood group gene-specified transferase estimations were studied in this condition for the first time. In 'affected' members, levels of B gene-specified transferase were low, and amounted to only 7--10% of the activity of a normal control. It is proposed that Bmos is correctly classified as a new form of weak B.
