Originally assessed by IARC on May 11, 2018.

“The sequence is present at a moderate frequency (0.5%), in the IgDiscover analysis. No information was provided by the submitter regarding analysis with partis or TIgGER. Haplotype analysis could not be performed. Analysis for chimerism did not provide evidence against the existence of the sequence.
Extensive analysis was submitted, including four additional IgDiscover analyses using modified germline gene reference datasets. Although IARC were strongly persuaded by the submitted data, it was agreed that the sequence should be moved to Level 0. Issues relating to the end nucleotides deserve wider discussion by the Working Group before IMGT is notified of such a potentially controversial decision. This will be raised by AC at the forthcoming WG meeting.”

It has been noted that neither partis not TIgGER had been able to infer IGHV3-7*02 or any variant thereof while these tools inferred IGHV3-7*01 (see supplementary information privided with the submission ).

(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.
