We analyzed the TCRβ clones in the repertoires of the cord blood samples, healthy donors in different age groups, and cancer patients by their commonalities (times a given CDR3 clone type that appears in a subgroup, divided by the sample size of the subgroup) and average counts (count summary of TCRβ sequences relevant to a given CDR3 clone type in a subgroup, divided by the times the clone type appears in the subgroup). Here, TRBV16 is linked to cancer.
