PRDM11 (PR/SET domain 11) is a transcriptional regulator belonging to the PR-domain family that acquired its subfamily identity during early vertebrate evolution 1. The gene functions as a putative tumor suppressor that binds to transcriptional start sites of target genes and regulates key oncogenes including FOS and JUN 2. Overexpression of PRDM11 inhibits cell proliferation and induces apoptosis 2, while loss of PRDM11 promotes MYC-driven B-cell lymphomagenesis, with PRDM11-deficient diffuse large B-cell lymphoma patients showing poor overall survival 2. Beyond hematologic malignancies, PRDM11 variants are associated with pulmonary function, having been identified in genome-wide association studies for forced vital capacity 3, and with thyroid function regulation, where PRDM11 variants influence serum TSH levels 4. Recent multi-omics analyses identified PRDM11 as a high-priority immune cell target with potential involvement in migraine pathogenesis through shared causal variants with migraine GWAS signals, with proposed therapeutic potential 5. These findings establish PRDM11 as a pleiotropic gene with critical roles in transcriptional regulation, cell cycle control, and immune-mediated processes.
