HLA-A and nonpapillary renal cell carcinoma: GLIPH2 clustering of pooled TRB-CDR3 sequences from the most frequent HLA-A (HLA-A*02:01, 6 tumors) or -B alleles (HLA-B*35:01, three tumors) among the 10 ccRCC tumors revealed only rare TRB specificity grouping with sequences from more than one patient (Supplementary Figures 2C, D) and no clusters with sequences from more than two patients.
