Paper
Mutated FGFR1 is an oncogenic driver and therapeutic target in high-risk neuroblastomaThe Journal of clinical investigation · 2026
Summary (written by the submitters)
Fibroblast growth factor receptor 1 (FGFR1) is recurrently mutated at p.N546 in neuroblastoma. We here sought to examine whether mutant FGFR1 is an oncogenic driver, a predictive biomarker, and an actionable vulnerability in this malignancy. FGFR1 mutations at p.N546 were associated with high-risk disease and rapid tumor progression, resulting in dismal outcome of neuroblastoma patients bearing this alteration.

Ectopic expression of FGFR1N546K induced constitutive down-stream signaling and interleukin-3-independent growth in Ba/F3 cells, indicating oncogene addicted proliferation. In FGFR1N546K;MYCN transgenic mice, neuroblastoma developed within the first days of life with fatal outcome within 3 weeks, reflecting the devastating clinical phenotypes of FGFR1 mutant high-risk neuroblastoma patients. Treatment with FGFR inhibitors impaired proliferation and pathway activation in FGFR1N546K-expressing Ba/F3 and patient-derived FGFR1N546K mutant neuroblastoma cells, and inhibited tumor growth in FGFR1N546K;MYCN transgenic mice and in a chemotherapy-resistant patient-derived xenograft mouse model. In addition, partial regression of FGFR1N546K mutant tumor lesions occurred upon treatment with the FGFR inhibitor futibatinib and low-intensity chemotherapy in a patient with refractory neuroblastoma. Together, our data demonstrate that FGFR1N546K is a strong oncogenic driver in neuroblastoma that is associated with failure of current standard chemotherapy, and suggest potential clinical benefit of FGFR-directed therapies in FGFR1 mutant high-risk patients.

Direct links to NCBI and ENA, no account and no request form. Pick by what you want to do: take the small processed table to look, the supplementary files to re-analyse, or the original raw data to start over.

1 · Just have a look

Processed table

The series matrix: one table of values per sample as the submitters processed it. The smallest download, and it opens in Excel or R. Start here to see what the data look like.

2 · Re-analyse it

Supplementary files

The count tables and other files the authors uploaded. Take only the samples you need, or the whole study as GSE313168_RAW.tar (it can run to tens of gigabytes).

3 · Start from the raw reads

Raw sequencing reads

The original FASTQ files, straight from the sequencer, held at ENA. Large, and you align them yourself, so only choose this if you need to re-process the study from scratch.

Raw reads on ENA ↗

What the files usually look like: For RNA-seq the counts are usually a table among the supplementary files (look for 'counts', 'expression', 'FPKM' or 'TPM' in the file name). The series matrix of a sequencing study is sometimes nearly empty.

Also filed as BioProject PRJNA1378732 and SRA study SRP654006. Searching any of these in the dataset finder brings you back here.
