?3). The amount of DRB loci varies from two to six for each haplotype, as well as Twenty various DRB loci/lineages have already been identified. The majority of region configurations include no less than one DRB6 pseudo-gene, nevertheless various other lineages, or certain alleles regarding various other lineages too, is probably not transcribed (de Groot ainsi que 's. 04). Several loci/lineages,
