Blood Group Systems
| ISBT № | System name | System symbol | Epitope or carrier, notes | Chromosome |
|---|---|---|---|---|
| 001 | ABO | ABO | Carbohydrate (N-Acetylgalactosamine, galactose). A, B and H antigens mainly elicit IgM antibody reactions, although anti-H is very rare, see the Hh antigen system (Bombay phenotype, ISBT #18). | 9 |
| 002 | MNS | MNS | GPA / GPB (glycophorins A and B). Main antigens M, N, S, s. | 4 |
| 003 | P | P1 | Glycolipid. Antigen P1. | 22 |
| 004 | Rh | RH | Protein. C, c, D, E, e antigens (there is no "d" antigen; lowercase "d" indicates the absence of D). | 1 |
| 005 | Lutheran | LU | Protein (member of the immunoglobulin superfamily). Set of 21 antigens. | 19 |
| 006 | Kell | KEL | Glycoprotein. K1 can cause hemolytic disease of the newborn (anti-Kell), which can be severe. | 7 |
| 007 | Lewis | LE | Carbohydrate (fucose residue). Main antigens Lea and Leb - associated with tissue ABH antigen secretion. | 19 |
| 008 | Duffy | FY | Protein (chemokine receptor). Main antigens Fya and Fyb. Individuals lacking Duffy antigens altogether are immune to malaria caused by Plasmodium vivax and Plasmodium knowlesi. | 1 |
| 009 | Kidd | dbMHC | Protein (urea transporter). Main antigens Jka and Jkb. | 18 |
| 010 | Diego | DI | Glycoprotein (band 3, AE 1, or anion exchange). Positive blood is found only among East Asians and Native Americans. | 17 |
| 011 | Yt or Cartwright | YT | Protein (AChE, acetylcholinesterase). | 7 |
| 012 | XG | XG | Glycoprotein. | X |
| 013 | Scianna | SC | Glycoprotein. | 1 |
| 014 | Dombrock | DO | Glycoprotein (fixed to cell membrane by GPI, or glycosyl-phosphatidyl-inositol). | 12 |
| 015 | Colton | CO | Aquaporin 1. Main antigens Co(a) and Co(b). | 7 |
| 016 | Landsteiner-Wiener | LW | Protein (member of the immunoglobulin superfamily). | 19 |
| 017 | Chido/Rodgers | CH/RG | C4A C4B (complement fractions). | 6 |
| 018 | Hh/Bombay | H | Carbohydrate (fucose residue). | 19 |
| 019 | Kx | XK | Glycoprotein. | X |
| 020 | Gerbich | GE | GPC / GPD (Glycophorins C and D). | 2 |
| 021 | Cromer | CROM | Glycoprotein (DAF or CD55, regulates complement fractions C3 and C5, attached to the membrane by GPI). | 1 |
| 022 | Knops | KN | Glycoprotein (CR1 or CD35, immune complex receptor). | 1 |
| 023 | Indian | IN | Glycoprotein (CD44 adhesion function?). | 11 |
| 024 | Ok | OK | Glycoprotein (CD147). | 19 |
| 025 | Raph | MER2 | Transmembrane glycoprotein. | 11 |
| 026 | JMH | JMH | Protein (fixed to cell membrane by GPI). | 6 |
| 027 | Ii | I | Branched (I) / unbranched (i) polysaccharide. | 6 |
| 028 | Globoside | GLOB | Glycolipid. Antigen P. | 3 |
| 029 | GIL | GIL | Aquaporin 3. | 9 |
| 030 | Rh-associated glycoprotein | RHAG | Rh-associated glycoprotein. | 6 |
| Langereis | LAN | ABCB6. Porphyrin transporter | 2 | |
| Junior | JR | ABCG2. Multi-drug transporter protein | 4 |

Famous quotes containing the words blood, group and/or systems:
“Later,
when blood and eggs and breasts
dropped onto me,
Daddy and his whiskey breath
made a long midnight visit
in a dream that is not a dream....”
—Anne Sexton (1928–1974)
“With a group of bankers I always had the feeling that success was measured by the extent one gave nothing away.”
—Francis Aungier, Pakenham, 7th Earl Longford (b. 1905)
“We have done scant justice to the reasonableness of cannibalism. There are in fact so many and such excellent motives possible to it that mankind has never been able to fit all of them into one universal scheme, and has accordingly contrived various diverse and contradictory systems the better to display its virtues.”
—Ruth Benedict (1887–1948)
