Rh null
The RH-null phenotype designates rare individuals whose red blood cells lack all Rh antigens. Two RH-null types, the regulator type (RHNR; 268150) and the amorph type (RHNA), arising from independent genetic mechanisms have been distinguished. The regulator type is caused by mutation in the RHAG gene (180297). Theo quy định của Hiệp hội Truyền máu Quốc tế, nhóm máu có tỷ lệ < 0,1% trong cộng đồng được gọi là nhóm máu hiếm. Loài người đa số có Rh dương, người da trắng có tới 85% Rh (+) và 15% có Rh (-). Ở Việt nam, tỷ lệ người có Rh (+) là 99,92%, Rh ( …

The rarest blood type is actually Rh-null, which is the lack of antigens in the Rh system. Less than 1 in 1,000 people have this blood type. However, individuals of this type can donate blood to just about every blood type. Before we proceed to understanding more about Rh-null being the most rare blood type along with various reasons for its ...This has led to speculation that Rh-Negative blood is related to Cro-Magnon ancestry going back to the upper Paleolithic period in Europe. Among the more exotic theories is the idea that the Rh …Rh null disease, which includes the amorph and regulator types, is a rare genetic disorder characterized by stomatocytosis and chronic hemolytic anemia. We studied here a German family transmitting a putative amorph Rh null disease gene and identified a rare mutation causing the loss-of-function phenotype. We analyzed the genomic and …
Each of the common blood types—A, B, AB, and O—comes in negative and positive versions (depending on whether or not red blood cells have a protein called an Rh antigen on their surface). Of these eight main categories, O positive is the most common, according to the Red Cross. AB negative is the rarest blood type in the U.S.So far Rh null has been reported in individuals of Caucasian, African, and Asian origin. Here, we report individuals from two families of Indian origin representing such a rare phenotype. Study design and methods: Serologic analysis was carried out by testing with anti-D, -C, -c, -E, and -e in Rh null individuals and their family members.

The ABO+Rh blood typing system is simplistic and handles only the three most relevant antigens. Accurate blood typing goes into way more detail with far more antigens and as a result there are a huge amount of categories.

The Rh system. Red blood cells sometimes have another antigen, a protein known as the RhD antigen. If this is present, your blood group is RhD positive. If it's absent, your blood group is RhD negative. This means you can be 1 of 8 blood groups: A RhD positive (A+) A RhD negative (A-) B RhD positive (B+) B RhD negative (B-) O RhD positive (O+)The RH-null phenotype designates rare individuals whose red blood cells lack all Rh antigens.

Nearly a century after the first publications which would lead to the recognition of the Rh blood group system (1,2), and 40 years after the molecular basis of the Rh antigens (Ag) were discovered (3,4), 55 Rh Ag, over 400 RHD and over 150 RHCE alleles are recognized by the International Society of Blood Transfusion (ISBT) ().
ua1871 A blood type is considered rare if fewer than 1 in 1,000 people have it. One of the rarest blood types in the world is Rh-null, which lacks any antigens in the Rh system.

Rh-null, which is the rarest blood group, is considered a “universal blood ...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.
