In findings that were published in the February issue of Nature Genetics, the team identified the molecules responsible for the two blood types as specialized transport proteins named ABCB6 and ABCG2.Īlthough the antigens for the Junior and Langereis (or Lan) blood types were identified decades ago, and have been known to cause complications in pregnant women carrying babies with incompatible blood types, the genetic basis of these antigens has been unknown until now. ![]() “More than 50,000 Japanese are thought to be Junior negative and may encounter blood transfusion problems or mother-fetus incompatibility,” said University of Vermont biologist Bryan Ballif. ![]() While these are rare worldwide, several ethnic populations are at risk for not carrying the Langereis and Junior blood type proteins, such as the Japanese and European Gypsies. Researchers from the University of Vermont, together with their French counterparts, have discovered two new blood types: Langereis and Junior. Although these 30 blood types are uncommon, they can potentially complicate blood transfusions. 5, 2012) – In addition to the major blood types A, B, AB and O, our red cells contain other antigens (membrane proteins or carbohydrates) such as Rhesus, Kell, and Duffy. ![]()
