Variant Subtype B, C
Method Sequence
Note Variant LPPvVAKEI (I31V) is found in both clades B and C. For Clade C, the consensus 31I form is present in 68% B*51- subjects, but the variant 31V form is present in all 6/6 B*51+ subjects. The 31V form is stably transmitted from B*51+ donors to B*51- recipients. In B-clade, where HLA-B*51 is not rare (as in C-clade, South Africa), the 31V form has become the consensus.
