Bombay Blood Group and Pregnancy

Molecular basis for H blood group deficiency in Bombay (Oh) and para-Bombay individuals.

The penultimate step in the biosynthesis of the human ABO blood group oligosaccharide antigens is catalyzed by alpha-(1,2)-fucosyltransferase(s) (GDP-L-fucose: beta-D-galactoside 2-alpha-L-fucosyltransferase, EC 2.4.1.69), whose expression is determined by the H and Secretor (SE) blood group loci (also known as FUT1 and FUT2, respectively). These enzymes construct Fuc alpha 1-->2Gal beta-linkag...

Emergency dilatation and curettage in a patient with Bombay blood group.

Bombay blood group is a rare autosomal recessive phenotype within the ABO blood group. It represents genetically suppressed A, B and H genes. When considering such patients for transfusion, only blood of identical Bombay type can be safely transfused. We are reporting a patient having Bombay phenotypic blood, underwent emergency dilatation and curettage with active per vaginal bleeding due to r...

Identification of a rare blood group, “Bombay (Oh) phenotype,” in Bhuyan tribe of Northwestern Orissa, India

BACKGROUND Blood group serology plays a vital role in transfusion medicine. The Bombay (Oh) phenotype is characterized by the absence of A, B, and H antigens on red cells and occurs rarely, especially in tribal populations of India. AIMS AND OBJECTIVES This is a field-based random population study in the Bhuyan tribal community. The study reports three cases of the rare Bombay (Oh) phenotype ...
