The gene-allele representation of the haplotype is:

HLA A*0301Cw*0702 : B*0702 : DRB1*1501 : DQA1*0102 : DQB1*0602

This is considered now the longest of the widely distributed ancestral haplotypes, its length is 4.8 million nucleotides and extends from TRIM27 gene . . . .The haplotype is nodal in Ireland but is also at high frequency in Switzerland, it has a subnode in the Pasiegos of northern Spain. There is some variance in the distribution of A3::DQ6 relative to A1::DQ2 in that there is more of a bias toward central and eastern Europe. Parts of the haplotype are spread into East Asia and even appear within the New world's indigeonous populations. DR15:DQ6 frequencies peak in central Asia, and it is suspect that this may be a point of Eurasian spread westward into Europe.

While there are some diseases associated with the haplotype, the frequency of association is less compared to A1::B8.
