Scientists Discover , New Set of Blood Types.<br />The most commonly known blood type <br />groups include A, B, O and Rh.<br />But 'The Hill' reports that there are dozens more.<br />A group of scientists, who published their study in the journal 'Blood,' have discovered <br />a new blood group called Er.<br />'The Hill' reports that it is the <br />44th blood group to have been found.<br />The blood group consists of five Er antigens that stem from genetic variations in the Piezo1 protein.<br />When antibodies match Er antigens, they can attach to them, which can cause immune cells to attack mismatched cells. .<br />'The Hill' reports that while the Er antigen had already <br />been discovered, this is the first time that different <br />mutations of the antigen have been detailed.<br />'The Hill' reports that being aware of possible differences in Er group compatibility may help health care workers to properly diagnose a patient. .<br />Discovering a new blood group system is like discovering a new planet. It enlarges the landscape of our reality, Daniela Hermelin, Saint Louis University School of Medicine, via 'The Hill'
