12 genes recurrently implicated in rhabdomyosarcoma — PAX3, FOXO1, MYOD1, FGFR4, NRAS, KRAS, HRAS, TP53, CDK4, IGF1R, MYCN, MDM2 — triaged for what can actually be aimed at them, alongside the trials, public datasets, literature and funding around the disease. Every figure below carries its source and retrieval date in the section it comes from.

1
drugs carry an FDA label naming rhabdomyosarcoma: Dactinomycin. This counts labels, not treatment — the disease is also treated with agents approved under broader indications
0
of the 12 genes above carries a drug approved in rhabdomyosarcoma — 72 drug entries reach them, 68 distinct once salt forms are merged, and 14 of those are approved for other indications. A statement about these gene targets, not about the disease
3
registered PD-1 cell-therapy trials in rhabdomyosarcoma, 2 active. Counted from ClinicalTrials.gov across 3 synonyms, deduplicated by NCT id, interventional studies only — the query is published in the JSON beside this page so the number can be re-derived
8
targets carry an Open Targets tractability signal and have no clinical programme of any kind: FOXO1, MYOD1, NRAS, KRAS, HRAS, TP53, MYCN, MDM2. FGFR4 has cell-therapy trials, so it is undrugged rather than untouched
374
human GEO series match the disease; 160 survive on-topic filtering, and only 5 are patient cohorts of 100+ samples
31
Europe PMC full-text papers name GSE108022 — the highest accession-mention count in the set. A mention is not proof of reanalysis, so read it as reach rather than reuse
$17.6M
NIH obligations in FY2025, up 171% since 2013 — while distinct core projects went 17 to 32. Both more projects (+88%) and larger awards, the latter carrying more of the growth; core projects are not the same unit as laboratories

Target landscape

Open Targets · retrieved 2026-09-16 · weekly

12 genes recurrently implicated in rhabdomyosarcoma, triaged for whether anything can actually be aimed at them. The zeros are the informative rows.

Of 12 recurrently implicated genes, 8 carry any drug at all. That is a statement about these 12 gene targets, not about the disease: Rhabdomyosarcoma does have labelled therapy — 1 drugs, listed in the next section.

Two different questions

The table below asks what can be aimed at 12 recurrently implicated genes. That is narrower than what is approved for the disease, and narrower again than what rhabdomyosarcoma is actually treated with, which includes agents approved under broader indications. All three are on this page and they are kept apart deliberately.

Cell therapy against PD-1

ClinicalTrials.gov · retrieved 2026-09-16 · weekly

PD-1 is the busiest cell-therapy antigen in rhabdomyosarcoma: 3 registered trials, 2 still active. It has no gene entry of its own and is reached through PDCD1: a form or product of that gene.

Public datasets, ranked

NCBI GEO + Europe PMC + iCite · weekly

374 human GEO series match rhabdomyosarcoma. Keyword relevance cannot tell a 159-sample patient cohort from a six-well cell-line experiment, so this ranking scores four things GEO does not expose: how often the accession is named in full-text papers, field-normalised citation impact, clinical annotation, and cohort type.

Of 374 series retrieved, 18 were dropped by the profile’s exclusion rules and 123 named the disease only in passing. The ranked set is a relevance-ranked sample, not a census, so the composition figures describe the sample only.

Where the gaps are

Derived from the sections above · recomputed on every refresh

Each card below is a disagreement between two of the tables on this page — a drug that exists but was never tried here, a target that looks tested and was not, a gene with no drug whose product has a busy clinical programme. They are computed from the same facts as the tables, so they cannot contradict them.

PAX3

No drug, no trial, no clinical programme of any kind. Whatever the biology says, nothing has been built.

FOXO1

No drug, no trial, no clinical programme of any kind. Whatever the biology says, nothing has been built.

MYOD1

No drug, no trial, no clinical programme of any kind. Whatever the biology says, nothing has been built.

KRAS

2 approved drugs (Adagrasib, Sotorasib) and no registered trial in rhabdomyosarcoma. The molecules exist; nobody has tested them here.

MYCN

No drug, no trial, no clinical programme of any kind. Whatever the biology says, nothing has been built.

How a machine reads this page

Static

This page is written to be quoted correctly by a model as much as read by a person. The same facts are available as JSON at the sibling URL below, which is what to cite. The cross-disease layer — burden, genes, drugs and antigens across every briefing — is described at /disease/api.json.

Fully server-rendered

Every figure is in the HTML at first byte. No JavaScript runs, no figure is fetched after load, and nothing on this page requires a renderer to see.

Every number carries a source

Each section names the API it came from and the date it was retrieved: Open Targets (2026-09-16), ClinicalTrials.gov (2026-09-16), openFDA (2026-09-16), NCBI GEO (2026-09-16), PubMed (2026-09-16), NIH RePORTER (2026-09-16).

Negatives stated explicitly

Where nothing exists for rhabdomyosarcoma — no drug, no trial, no approval — the page says so in those words rather than omitting the row. An absent row is unquotable; a stated negative is the finding.

Denominators, not just percentages

Every share is printed with the count and the total it came from, so a figure can be checked rather than taken.

The filters are published

5 exclusion patterns are applied to free text before anything is ranked, because RD (unlistable) and RH30 is used as a model system in RD is used as a myogenic and enterovirus host line; RH30 is used for the disease. What was removed and why is stated in each section rather than silently applied.
