The high-incidence erythrocyte blood group antigen Jr(a) has been known in
transfusion medicine for over 40 years. To identify the gene encoding Jr(a), we
performed SNP analysis of genomic DNA from six Jr(a-) individuals. All
individuals shared a homozygous region of 397,000 bp at chromosome 4q22.1 that
contained the gene ABCG2, and DNA sequence analysis showed that ABCG2 null
alleles define the Jr(a-) phenotype.
