Objective To study genetic characteristics of two individuals with para-Bombay phenotypes and their family members. Methods ABO and H antigens were detected with routine serological techniques. The entire coding region of FUT1 and FUT2 gene was amplified by polymerase chain reaction( PCR). Afterwards,PCR products were directly sequenced. Results The RBCs of both probands did not agglutinate with H antibody,therefore they were confirmed as paraBombay phenotype Amh and Bmh respectively. Direct sequencing indi...
