Abstract
The 8p11 myeloproliferative syndrome (EMS) is an aggressive neoplasm caused by the fusion of various partner genes to fibroblast growth factor receptor 1 (FGFR1). Various FGFR1 fusions are associated with subtly distinct disease phenotypes. Here, we report a new translocation at the FGFR1 locus in a patient who carried t(1;8)(q25;p11.2) and presented with myeloproliferative neoplasm-like symptoms. The patient was characterized by myeloid hyperplasia of bone marrow, markedly elevated numbers of monocytes, and normal to mildly elevated eosinophils. Initial fluorescent in situ hybridization analysis confirmed that FGFR1 in this patient was disrupted. Subsequent analysis led to the identification of a novel translocation, in which exon 23 of the translocated promoter region (TPR) gene at chromosome band 1q25 was fused to exon 13 of FGFR1 (RefSeq NM_0231102.2). The TPR portion of the fusion protein contains putative functional motifs including an N-terminal TprMet domain, nuclear pore complexes associating domain, and multiple coiled-coil domains. It is likely that one or more of the motifs from TPR contribute to dimerization, resulting in constitutive activation of the FGFR1 kinase domain. Our results further support a critical role of FGFR1 in the pathogenesis of EMS and may lead to more accurate diagnosis and potential targeted therapy.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
