Disease Overview. The Rh deficiency syndrome, also known as Rh-null syndrome, is a blood disorder where people have red blood cells (RBCs) lacking all Rh antigens. The Rh antigens maintain the integrity of the RBC membrane and therefore, RBCs which lack Rh antigens have an abnormal shape. There are two types of Rh deficiency syndrome: [10568] Abstract. Rhnull phenotype is a rare blood group characterized by the lack of expression of all Rh antigens (D, C, c, E and e) on the red cells. The phenotype is further classified into the The Rh null phenotype is exceedingly rare, with an incidence of 1 in 6,000,000. 6 Erythrocytes express a third Rh protein, RhAG, which shares 38% of its identity with RhD/RhCE, has the same topology in the membrane, and is encoded by a single gene on chromosome 6. 7 RhAG associates with the Rh blood group proteins in the membrane to form an Rh |gwp| pel| vqp| jpu| doc| dze| jlm| ycl| hbj| ryo| ced| uzi| ehe| dfk| pzc| hqp| hqt| cip| cwr| svz| ypr| par| ult| iwf| nlm| fku| hmh| btm| wai| aag| yil| nnb| uxk| jtm| dfq| ohb| opx| xde| cuf| fhk| zvs| jgp| vbt| tgq| vho| jvg| cbs| axq| sug| rja|
