(a) Shared V3J clonotypes from sequenced Ig heavy chains.
(b) (Left panel) Shared V3DJ clonotypes from
sequenced Ig heavy chains with HCDR3 lengths from 3 to 28 amino acids.
(Right panel) Shared V3DJ clonotypes from synthetic HIP
repertoires with HCDR3 lengths from 3 to 28 amino acids. The percentage overlaps
were based on the average of 1,000 comparisons from bootstrap testing involving
synthetic HIP repertoires. The average and standard error of the mean (s.e.m.)
for the percentage overlaps was 0.03% (5.0 × 10−5)
between simHIP1 and simHIP2, 0.03% (4.9 × 10−5) between
simHIP1 and simHIP3, and 0.02% (6.0 × 10−5) between
simHIP2 and simHIP3. The average and s.e.m. for the percentage overlap between
simHIP1 and simHIP2 and simHIP3 was 0.0004% (6.9 ×
10−6). The V3DJ overlap count between all three sequenced
repertoires (n = 3,641 common clonotypes) ranked highest in the
1,000 comparisons giving a P = 1.0 ×
10−4 (see Extended Data Fig.
2e for normalized histogram of common clonotypes between synthetic
sets). (c) Fold change in VH+JH usage between
Shared HIP1+2+3 (n = 29,062 unique
clonotypes) and all HIP subjects (designated: All HIP1+2+3,
n = 36,064,712 unique clonotypes). (d) Common
motifs in Shared V3J clonotypes with long CDR3s shown as a
WebLogo22.
(e) Somatic variant count for V3J clonotypes from the
Shared HIP1+2+3 collection whose somatic variants had
identical CDR1 and CDR2 amino acid sequences plotted in order of decreasing
frequency. Numbers in parenthesis denote V3J clonotypes having the largest
number of somatic variant counts.
