IARC Meeting 61 (October 13th 2020): The meeting considered the inference of the variant IGHV3-2101_a184g_t190a_a191c in the VDJbase dataset of sample P1_I80_S1. The sequence was seen in 2.73% of all unmutated rearrangements, with 1207 sequences including 1054 perfect matches to the inferred allele. There was abundant variation in the CDR3 regions of the aligned sequences. IGHV3-2101 was also present in the genotype, at a similar frequency (2.37% of all unmutated sequences, 1066 sequences, 917 unmutated sequences). Plots of the final 3’ nucleotides were unavailable, and no haplotyping data was available. The sequence was tentatively affirmed as a Level 1 sequence, and the final 3’ nucleotides will be considered at a later date, when terminal nucleotide plots become available, at which time the affirmed sequence will be noted in the IARC minutes. IARC meeting 80 (September 27th, 2021): IGHV3-2101_A184G_T190A_A191C was inferred in the genotype of subject S76 (VDJbase: P1_I80). This inference has previously been pre-assessed at IARC meeting 61 (https://www.antibodysociety.org/wordpress/wp-content/uploads/2020/12/Meeting-61-13_10_20-minutes.pdf). The genotype also carried IGHV3-2101. Both alleles were represented in high numbers (2.9% and 2.5% of the total unmutated population). IGHV3-2101_A184G_T190A_A191 was represented by 1306 sequences, 1092 unmutated sequences, an allelic frequency of 53%, and 1069 unique CDR3s in the unmutated sequence set. Haplotyping based on differences in IGHJ6 alleles was not possible for this dataset. >IGHV3-2101_A184G_T190A_A191C GAGGTGCAGCTGGTGGAGTCTGGGGGAGGCCTGGTCAAGCCTGGGGGGTCCCTGAGACTCTCCTGTGCAGCCTCTGGATTCACCTTCAGTAGCTATAGCATGAACTGGGTCCGCCAGGCTCCAGGGAAGGGGCTGGAGTGGGTCTCATCCATTAGTAGTAGTGGTAGTACCATATACTACGCAGACTCAGTGAAGGGCCGATTCACCATCTCCAGAGACAACGCCAAGAACTCACTGTATCTGCAAATGAACAGCCTGAGAGCCGAGGACACGGCTGTGTATTACTGTGCGAGAGA The sequence is inferred at Level 1.
