Table 4.

Comparison of part of the sequences of DQA1*01:01:01:01, DQA1*01:06, and DQA1*01:02:01:04/14 illustrating the DQA1*01:06 may have arisen by a gene conversion event with double cross over, recombining DQA1*01:01:01:01 and DQA1*01:02:01:04/14, and an additional mutation at position 3974

Heterozygous positions that are identical for DQA1*01:01:01:01 and DQA1*01:06 are in light grey, heterozygous positions identical for DQA1*01:02:01:04/14 and DQA1*01:06 are in dark grey

For intron 1, only the first and last 3 heterozygous positions are shown

I intron, E exon, UTR untranslated region, number indicates the position of the genomic sequence according to the IPD-IMGT/HLA database, “.” = deletion, “*” = unknown sequence
