Gene Summary

[ - ] NCBI Entrez Gene

Gene ID 28 Official Symbol ABO
Locus N/A Gene Type protein-coding
Full Name ABO blood group (transferase A, alpha 1-3-N-acetylgalactosaminyltransferase; transferase B, alpha 1-3-galactosyltransferase)
Description ABO blood group (transferase A, alpha 1-3-N-acetylgalactosaminyltransferase; transferase B, alpha 1-3-galactosyltransferase)
Chromosome 9q34.1-q34.2
Also Known As ABO blood group (alpha 1-3-N-acetylgalactosaminyltransferase, alpha 1-3-galactosyltransferase); ABO glycosyltransferase; B(A) alpha-1,3-galactosyltransferase; histo-blood group A2 transferase
Summary This gene encodes proteins related to the first discovered blood group system, ABO. Which allele is present in an individual determines the blood group. The 'O' blood group is caused by a deletion of guanine-258 near the N-terminus of the protein which results in a frameshift and translation of an almost entirely different protein. Individuals with the A, B, and AB alleles express glycosyltransferase activities that convert the H antigen into the A or B antigen. Other minor alleles have been found for this gene.
