 It is commonly found in linkage disequilibration within the A*3301-Cw*0802-B*1402 haplotype which can be extended to DRB1 and DQB1 in certain instances(See Below).The source of its general expansion appears to be the middle east or the levant, as it is found in the Palestinian population.B14 splits into B64 (B*1401) and B65 (B*1402) but the only Arabian people which show both antigens are the United Arab Emirates.
