Originally approved by IARC on March 9, 2018.

“The sequence was inferred [..] using IgDiscover, and [..] using both Partis and TIgGER. The number of unique CDR3 used by sequences with exact matches to the inferred germline allele represents 1.3% of all unique CDR3 [unmutated frequency: 1.17%] associated to exact IGHV matches in the genotype, according to IgDiscover. There were at least 775 unique rearrangements, utilizing 22 D genes and 7 J genes. The allele was the more frequently utilized allele, with an expression ratio of 56:44 with the *01 allele. The inference was supported by haplotype analysis using IGHJ6*02/*03.”
