Originally approved by IARC at Meeting 57 on July 7, 2020, where it was noted:

“The sequence was seen in 1.61% of all unmutated rearrangements, with 9,680 sequences including 1925 perfect alignments to the inferred allele. There was abundant variation in the CDR3 regions of the aligned sequences. A second IGLV3-21 allele, IGLV3-21*03, was also present in the genotype, at a higher frequency, but the inferred allele still accounted for 35% of all IGLV3-21 alignments. Haplotype data is unavailable. Plots of the final 3’ nucleotides were considered, but the variability seen made it impossible to consider the final two nucleotides of the sequence. These were not part of the Genbank submission. The sequence, up to and including nucleotide 339, was affirmed as the Level 1 sequence, IGLV3-21*i01. Uncertainty regarding nucleotides 340-341 will be indicated in IARC and OGRDB publications by two dots at the end of the affirmed sequence.”
