“The sequence is present at relatively high frequency (0.6%), in the IgDiscover analysis. It was inferred by IgDiscover, TIger and Partis. Haplotype analysis showed two IGHV4-4-like sequences associated with the IGHJ6*02 haplotype – this inference and a second inference that is most similar to IGHV4-4*08. The likely major duplication of B16 is associated with the IGHJ6*03 haplotype. Given the similarities between IGHV4-4*08 and IGHV4-61, and given that this haplotype does not include an IGHV4-61 sequence, the committee concluded that this sequence could be accepted as Level 1. Although in this analysis the sequence was shown to be most similar to IGHV4-4*01, the committee believes that this inference extends the partial sequence IGHV4-4*03.”

(April 12, 2019) In line with IARC policy, the submitted sequence was recognized up to and including nucleotide 319. A trailing “.” indicates IARC’s opinion that the sequences likely to contain an additional/additional 3’ nucleotide(s) for which there is insufficient evidence to make an affirmation.
