At the IARC meeting on July 20th 2020, the following features of the inference in the S000028 submission were noted:

The sequence was seen in 1.49% of all unmutated rearrangements, with 14,472 sequences including 1776 perfect alignments to the inferred allele. There was abundant variation in the CDR3 regions of the aligned sequences. The IGLV6-57*01 allele was also present in the genotype, at a somewhat lower frequency. Haplotype data is unavailable. Plots of the final 3’ nucleotides were considered, but the variability seen made it impossible to be certain of the final two nucleotides of the germline sequence. The sequence, up to and including nucleotide 333, was affirmed as the Level 1 sequence, IGLV6-57*i01. Uncertainty regarding nucleotides 334-335 will be indicated in IARC and OGRDB publications by two dots at the end of the affirmed sequence.
