WebJun 10, 2013 · Conversion of i antigen into an I-active structure requires the activity of the I-branching enzyme, beta-1,6-N-acetylglucosaminyltransferase (GCNT2; 600429), which adds the decisive GlcNAc-beta-1-6 branch onto the straight poly-LacNAc chains. Expression of the i and I antigens on red blood cells (RBCs) is reciprocal and developmentally regulated. WebMolecular testing to predict the red blood cell phenotype does not always reflect the phenotypic expression of the blood group antigen. This may occur in cases where the individual has genetic variation that silences or alters the blood group antigen expression that is not included in the target region of the test, and also may occur with RhD ...
