DQ Wa gives rise to a DQ beta restriction fragment pattern indistinguishable from that of the DQw3.2 sub-type of DQw3.

DQ beta restriction fragment patterns have been obtained from five DRw8 cell lines homozygous for the null DQ allele, DQWa. The enzymes Bgl II, Bam HI and Pvu II generate DQ beta patterns which are indistinguishable from those obtained from cell lines homozygous for DQw3.2.
