Although PDL copy-number variations are well characterized, a detailed and comprehensive analysis of structural rearrangements (SRs) and associated phenotypic consequences is largely lacking. Here, we used oligonucleotide capture sequencing of 67 formalin-fixed paraffin-embedded tissues derived from primary B-cell lymphomas and 1 cell line to detect and characterize, at base-pair resolution, SRs of the PDL locus (9p24.1; harboring PDL1/CD274 and PDL2/PDCD1LG2). We describe 36 novel PDL SRs, including 17 intrachromosomal events (inversions, duplications, deletions) and 19 translocations involving BZRAP-AS1, CD44, GET4, IL4R, KIAA0226L, MID1, RCC1, PTPN1 and segments of the immunoglobulin loci. Moreover, analysis of the precise chromosomal breakpoints reveals 2 distinct cluster breakpoint regions (CBRs) within either CD274 (CBR1) or PDCD1LG2 (CBR2). To determine the phenotypic consequences of these SRs, we performed immunohistochemistry for CD274 and PDCD1LG2 on primary pretreatment biopsies and found that PDL SRs are significantly associated with PDL protein expression. Finally, stable ectopic expression of wild-type PDCD1LG2 and the PDCD1LG2-IGHV7-81 fusion showed, in coculture, significantly reduced T-cell activation. Taken together, our data demonstrate the complementary utility of fluorescence in situ hybridization and capture sequencing approaches and provide a classification scheme for PDL SRs with implications for future studies using PDL immune-checkpoint inhibitors in B-cell lymphomas."xsd:string |
