%X <B>BACKGROUND: </B>D antigen is one among the most immunogenic antigens and is the most common cause of Haemolytic Disease of Fetus and Newborn (HDFN). The D-phenotype is a rare Rh variant in which none of the RhCE antigens are expressed on the red cell surface. Individuals having D-phenotype are capable of producing a rare alloantibody named as anti-Rh17(Hr° ) in response to pregnancy or transfusion and has the potential to react with C/c and E/e antigens causing severe haemolytic transfusion reaction (HTR) and haemolytic disease of fetus and newborn (HDFN).<BR><B>METHODS: </B>We have encountered a case of severe HDFN with an accidental discovery of D- phenotype of the mother with anti-Rh-17 antibodies. D- phenotype has been confirmed with molecular typing along with genotyping of all family members.<BR><B>CONCLUSIONS: </B>Rare phenotypes like D- individuals especially if allo-immunised are of great concern at times of transfusion requirements. Hence, proper identification of these individuals are important to contribute them to the rare donor pool and to adopt adequate patient blood management strategies.
